The microscopic organism grows easily in salt water without any trouble.

Eneko Ganuza grew up in Spain’s Basque country, not far from the sea. As a student studying oceanography, he fell in love with a seemingly unlikely specimen: microalgae. He was captivated by the way the microscopic plant-like organisms transformed miles of ocean into brilliant algal blooms, giving life to countless other marine creatures.
“Algal blooms are like a rainforest of life in the desert of the ocean” he says now.
Ganuza went on to become a leading microalgae scientist. As vice president of research and development at iWi, a Texas-based nutrition company that produces algal-based products on one of the world’s largest algae farms, he now applies his knowledge of one of the world’s smallest plants to solving global problems. Ganuza and his colleagues at iWi firmly believe that marine microalgae could help alleviate many of our most pressing environmental problems—foremost among them, freshwater shortage.

“It’s fair to say that water has been the underlying reasons for a lot of wars,” Ganuza says. “As the climate changes, this is becoming a more and more critical issue.” And indeed, according to the Pacific Institute, a non-profit group dedicated to protecting and preserving global fresh water, water has been at the heart of over 600 known conflicts around the world. Competition for that life-giving resource is only set to increase in the future, as fresh water becomes scarcer in much of the world due to drought and saltwater encroachment in coastal areas. A report released by the United Nations’ Intergovernmental Panel on Climate Change (IPCC) in September warns that sea levels are very likely to rise between 2- and 3.6-feet by 2100 (but the rise could be much higher, to as much as 6.5 feet, should the Antarctic ice melt faster than predicted).
Despite these strains on our planet’s freshwater supply, the demand for that resource is increasing, including for water-hungry crops and livestock, not to mention hydropower development and other human needs. By some estimates, as the human population continues to balloon, the world will suffer a freshwater shortage of 40 percent by 2050. “That’s tomorrow, by the way!” says Miguel Calatayud, chief executive officer of iWi. “My son will be 36, then, and probably fighting in the third world war—for water.”
Another IPCC report, published in August, warns that humans are exploiting the world’s water resources at an “unprecedented rate.” Central to this problem, the authors write, is our food production system. A breathtaking 70 percent of the world’s freshwater is currently used for producing crops and raising livestock. According to a 2010 UNESCO report, soybeans require 1,000 gallons of fresh water for every single pound of produce, chicken requires 4,300 gallons, and beef requires 17,700 gallons. And a single pound of almonds requires a whopping 23,700 gallons of fresh water.
If the cultivation of microalgae continues to spread around the world, it may help lighten the strain on our precious freshwater resources. Nannochloropsis, the type of microalgae that iWi grows, is a marine species. It thrives in brackish or salt water — not fresh water. This means the iWi system requires three orders of magnitude less water (5 gallons of fresh water per pound) to produce food than any other terrestrial crop.
While water for growing Nannochloropsis could come in the form of fresh water enhanced with salt and nutrients, it could just as easily come from the ocean. It could also come from vast underground salt and brackish water reservoirs found all over the world—including in many deserts and arid places where traditional agriculture is hardly viable. iWi currently relies on such aquifers at its Texas and New Mexico farms.
iWi’s algae farms in the desert.
“Many arid areas on the planet are full of groundwater, but the problem is, it can’t be used because of its high salinity,” Calatayud says. “We can grow our algae in that salt water, which otherwise couldn’t be utilized to produce any other crop.”
Another boon for Nannochloropsis’ attractiveness as a sustainable, hardy crop is that it’s not overly picky about the salt content of the water it’s grown in. It’s equally happy in water that has about half the salinity of seawater, or in water that has nearly twice the salinity—or anything in between. “That means we can account for much of the evaporation, while the salinity of the cultures keeps building up in the ponds,” Ganuza says. That’s helpful, because the iWi tanks are completely exposed to the open, dry air. Their tanks in Imperial, Texas, don’t even have artificial lining, but instead just rely on the nearly impermeable clay-heavy soil that naturally occurs there.
Open-air cultivation of this sort is completely normal in the farming world, and iWi has demonstrated that microalgae can be grown like any other crop. “Industrial microbiology is very much based on running closed systems under sterile conditions,” Ganuza says. “But this is the simplest way of producing microalgae that you can imagine—we are farming.”

Recycled water returning to the farm.
Perhaps most importantly of all, iWi is able to recycle about 95-97 percent of the water used to grow its Nannochloropsis (product recovery and processing account for the lost three percent). At the Columbus, New Mexico, farm, for example, iWi harvests roughly 30,000 gallons of pond culture to make 300 gallons of concentrated algae, and then returns just under 29,000 gallons of water to the pond for reuse. To recycle the water, the algae is micro-filtered out using a hollow fiber membrane system, which is a low-energy, chemical-free technology. Only crystal-clear water is left behind, and that’s put right back into the pond.
Calatayud imagines eventually democratizing algal farming by bringing similar systems to remote areas in Africa, Asia and beyond—to the types of places that have plenty of saltwater reservoirs and open space, but not enough fresh water to grow crops. “The world is full of areas like this that nobody uses,” he says. Nannochloropsis could be a source of export income, he believes, as well as a local source of food. “In addition to alleviating the global pressure on fresh water resources,” Calatayud says, “we could really make a positive difference for families and communities around the world.”

Massive Science : The second big wave of crop domestication is happening within our lifetimes

"The first steps towards microbial agronomy are being taken in an oasis in the desert."
Microalgae are invisible to the human eye, and yet under certain circumstances, they can achieve densities visible from space. In keeping, we often overlook their vast influence on our most valuable ecosystems. These microscopic plants contribute at least half of the world’s primary oxygen production. They sustain the marine food chain as we know it. And yet, their current influence is only a fraction of their inherent potential. Just as the domestication of terrestrial plants in the Neolithic period was a necessary precondition for feeding humanity as we know it today, domesticating microalgae may be the key to sustainably feeding our ever-growing population in the future. If we harness and concentrate their power, these tiny mainstays of the marine food chain may soon become a pillar of our diets.

The Power of Microalgal Blooms
Microalgal blooms occur in upwelling waters, when nutrient-rich, deep water rises to the upper illuminated layers of the ocean. Not coincidentally, this is the 1% of the ocean where more than half of the world’s commercial fishing occurs. The open ocean is a desert by comparison, making these spaces small oases, which happen to have the primary productivity of terrestrial rainforests. Microalgae bloom under very specific conditions, nesting the marine food web, and triggering atmospheric carbon capture. And their blooming is a far more transient phenomena than in terrestrial plants. Their organic matter turnover time (2-6 days) is three orders of magnitude faster than terrestrial plants (19 years). They produce half of the world’s primary oxygen using only 0.2 % of the plant global biomass. If only we could harvest those microscopic plants quickly enough before they sink forever into their depths!
An unlikely interaction of biology, physics, and chemistry produces this rare event in nature: the proliferation of a single, dominant, microbial species. In nature, most microbes (such as yeast, bacteria, fungi) bloom in a complex community, much in the same way wilderness areas are formed in a consortium of plant species. These naturally-occurring microalgal blooms should be regarded with the same awe as a cornfield spontaneously growing in the middle of the jungle. They pose a challenge: what if we could select a microalga with the right nutritional profile from the dizzying array in our oceans, and artificially mimic the “blooming” of a nutritional algae species?
Harnessing Microalgae
A growing community of scientists and farmers has been working towards mastering and reproducing microalgal blooms in an agricultural setting. They are working on the assumption that this diverse and valuable resource can be domesticated like any other terrestrial crop. Microalgae domestication is a broad and evolving concept, which draws on many different technologies, some of which are common to the cultivation of other microbes in industrial microbiology, but ultimately are applied with the simplicity of a farming operation.
As Vice-President of R&D of the microalgae company iWi, I have focused my efforts on the Nannochloropsis species, because of its capacity to produce a nutritionally important omega-3 fatty acid that terrestrial plants are unable to make. This species produces eicosapentaenoic acid (EPA 20:5 n-3) attached to glycolipids and phospholipids, which is likely the most bioavailable form of omega-3. We have studied how, why, and under what conditions they express this product of interest, and we are continuously devising strategies to express as much of it as possible.

We selected this strain of Nannochloropsis for its capacity to thrive under our target environmental conditions, using techniques such as high throughput screening and directed evolution. While those initial approaches to finding better strains are common to industrial microbiology, our goal is to grow algae using a simpler and more sustainable farming approach. We reproduce a microalgal bloom using open ponds all year-round in a consistent and repeatable way, while amplifying the intensity of those blooms beyond what we typically observe in nature. This is a new type of agronomy: instead of growing fields full of wheat or corn, we are farming microbes.
Microbial Agronomy
This new concept of “microbial agronomy” operates at the intersection of agriculture and industrial microbiology. We seek to reproduce and enhance monoalgal blooms like those that spontaneously occur in nature by studying the biology of not just our target microalga, but also the microbiome associated with the algal bloom.
Producing commodity products from microbes may require a technology that can address microbial control in a manner different from what is common in industrial microbiology. Instead of physically separating our culture from contaminants using costly stainless steel fermenters and steam sterilization, our use of open ponds is an attempt to create an artificial microbiome that helps support the microalgal bloom. That means harnessing the natural capacity of microalgae and their hosts to thrive under exposed conditions. Growing microbes in open ponds is a farming practice rather than an industrial operation. In doing so, we are democratizing industrial microbiology into something that is closer to agriculture.
There are a wide range of techniques and biotechnological strategies that allow us to safely grow microalgae consistently throughout the year. We monitor our cultures, optimizing them for each season and geographical location. Fortunately, our algae like to grow in conditions that a lot of other microbes don’t like, which makes it a bit easier to protect from bad players. When necessary, we apply the same integrated pest control strategies one would apply to any other crop. We use techniques such as adjusting the pH or salinity of our cultures when needed, but we never use herbicides or pesticides.
Transforming the role algae play in our society
Microbial agronomy fills an economic niche that no other food production process can, and does so in a highly sustainable way. Algae can take resources once seen as waste and turn them into plant-based food such as omega-3 and protein. At iWi, rather than drawing omega-3 from caught fish and krill, we “skip the middle fish” and go straight to the original source of this nutrient. Algae grown in shallow open ponds in geographical locations that receive a lot of sunshine (such as our site in the Chihuahua desert in New Mexico) can achieve much higher cell densities than in nature.
This process utilizes arid land that can’t be used for other farming purposes, brackish water that eliminates our reliance on the planets already strained fresh water supply, and sunlight which is in ample supply on our farms. These are the first steps towards the domestication of microalgae in our lifetime. Just last year algae were included for the first time as a crop in the US Farm Bill. These steps are opening the door for new agricultural processes that will eventually transform the role microbes like microalgae play in our society.

"High in protein and low in carbon footprint, algae is a breakthrough for feeding the world in a changing climate."
“Algae? But... isn’t that gross?” That’s what Rebecca White commonly hears from surprised people at her booth at trade shows, after the unsuspecting visitors find out the snack bar they just ate, and actually really liked, contains algae.
White is a research scientist at iWi, a nutrition company that runs one of the largest algae farms. She isn’t offering snacks filled with algae just to show people that the mossy greens can be added to food without making it taste or smell like pond water. The real mission is to discuss algae’s potential as a solution for a much bigger problem: the food security of our planet.
We will soon be running out of food. The projected population of the world in 2050 will require a 70 percent increase in food production, but we are already stretching our resources with the way we grow food today, a new United Nations report warned yesterday. Land is turning into desert, rising temperatures are cutting crop yields, and soil is becoming lifeless due to overuse. Seventy percent of the world’s available freshwater is used for agriculture and raising livestock. Livestock and the food they consume generate 14 percent of all greenhouse gas emissions from human-related activity, contributing to climate change, more droughts and land erosions. It’s a vicious cycle that experts say we are running out of time to break. “We need a farming revolution,” says Miguel Calatayud, the CEO of iWi.
Algae can be grown in areas where other crops won’t survive. They don’t need soil or freshwater. What they do need is a lot of CO2, which has led some to consider them for sequestering emissions from power plants. The algae’s excellent nutritional profile is another appeal. They have all essential amino acids, the building blocks of proteins, plus vitamins, minerals and essential fatty acids like omega-3.
Algae might not replace animal protein entirely but could help reduce our reliance on conventional sources of protein and reduce our carbon footprint. iWi wants to make it an everyday food by turning it into a protein shake, a powder you sprinkle over pasta, or to be mixed in anywhere else. “It can be a supplement. Or it can be an ingredient in basically anything,” White says.

It’s an ambition that has become sensible only after a long run of trial and error. After all, the US government recognized algae as a crop for the first time in the 2018 farm bill, and the agricultural know-how that exists for growing other crops is still in the making for this ocean dwelling plant. Scaling algae production is no easy task but iWi is employing a few creative tricks to make it happen. “We’ve been able to crack the code,” Calatayud says. Here’s how:
From the bottom of the food chain to a future food
iWi grows its algae in 48 ponds built in the deserts of New Mexico and Texas. Each bigger than a football field, the ponds are filled with the well water pumped from salty aquifers underneath. Farms previously on that land left after the aquifers became too salty. The watery green soup brewing in the ponds contains a million liters of a strain of algae called Nannochloropsis, with microscopic cells smaller than 5 microns.
To grow algae there are several concerns to address — first is to protect the crop from being eaten by other organisms before we get to it. “It is literally the bottom of the food chain in the ocean. Lots of things in the world eat it,” White says. “And so to be able to grow it, you have to be able to protect it from all the things that eat it without introducing anything harmful into the system.”
Algae farming is so new that there are no pesticides, insecticides or herbicides developed to protect algae (there are, however, lots of algaecides for killing it). That limitation, plus sustainability considerations, led the iWi team to turn to integrated pest management, which focuses on early detection and prevention of problems rather than fixing them after they’ve already happened. “We have figured out how to grow the algae in such a way that the ponds are an optimized environment for the algae to grow, and not much else,” White says. For example, when microscopic rotifers start to eat the algae, she controls them by introducing a sudden pH swing or tweaking the nitrogen source in favor of the algae and to the detriment of rotifers. “These little tricks around operational parameters allow us to grow the algae in open systems at very large scale,” she says.
iWi
Then comes harvesting, which has to be sustainable and energy efficient for algae to be considered an attractive food alternative. iWi uses a Zobi Harvester, a device recently developed under a grant from the Department of Energy. Touted as a breakthrough for the algae industry, this filtration-based system extracts algae from the water using low energy and no chemicals. The crystal clear water coming out the other end is then put back in the pond. “That’s what significantly reduces our water footprint,” White says.
Harvesting comes in precise cycles so to not disturb the micro-ecosystem of the algae and halt their growth. Every time the density of the algae reaches a certain point, about 25 percent of the pond water is run through filtration to extract the algae. The remaining algae continue to replicate in the diluted water and the cycle repeats — it’s just like what you do with sourdough starter.
iWi then processes the algae to extract oil, which has high levels of omega-3 and is sold as supplements. What’s left is proteins and carbohydrates, which the team is working on bringing to the market as protein products. “We’re trying to make it as flavorless as possible,” White says. So far the extracted protein is good enough that White herself can’t detect it in foods, but the product still needs to clear the high bar of supertasters.
With the inclusion of algae in the farm bill, White and other algae farmers hope that federal grants will fuel progress in algae technology and elevate algae to a mainstream crop. It may take a few years, but the tiny green cells seem finally on a steady track towards the top of the food chain.

"It's something to really consider—especially if you're not a fan of fish."

Those bright blue smoothies and puddings that have taken over your Instagram feed aren’t just pretty to look at. They also pack a serious health punch, thanks to the same superfood: algae.
The term algae actually refers to a family of aquatic plants that's estimated to include anywhere from 30,000 to more than 1 million species. You've likely heard of some of the more popular varieties, such as spirulina, chlorella, nannochloropsis, and seaweed, and for good reason. Not only are they tasty—and turn ho-hum drinks a vibrant blue hue— but a growing body of evidence suggests they're also very good for you.
Here’s a look at the proven benefits of algae and why you might want to add it to your diet—especially if you don't eat a ton of fatty fish. (More on that in a sec!) Plus, some creative and easy ways to get your fill.
The health benefits of algae
It promotes heart health.

Let’s start by talking about the incredible benefits of the omega-3s found in fatty fish like salmon and tuna. (Fun fact: Fish get omega-3s from the algae and seaweed they eat.) These essential fatty acids are thought to promote heart health, help protect against breast and colorectal cancer, fight cognitive decline, ease rheumatoid arthritis symptoms, and even reduce the risk for depression, according to the National Institutes of Health.
The body can only use about 15% of the omega-3s found in most plants, but algae is the exception.
If you’re not a fan of fish (or only eat it once in a while), you might aim to get your omega-3s from plant-based sources like walnuts or flaxseeds. The only problem? The omega-3s found in most plants, while good for you, aren’t nearly as potent as the ones found in fish, explains registered dietitian Isabel Smith. In fact, the body can only use about 15 percent of the omega-3s found in most plants, notes the NIH.
But algae is the exception. It’s a plant-based source of omega-3s, and unlike nuts and seeds, the fatty acids within it are easy for the body to absorb. In fact, research has shown that the omega-3s found in certain species of algae, such as nannochloropsis and spirulina, have the same bioavailability as those found in salmon.
That’s why Smith is such a big fan. “I often recommend algae-based omega-3s for people who are vegetarian or vegan, for those with fish allergies, or anyone who has trouble getting enough omega-3s,” she says.
It can help lower your risk for certain diseases.

If you’re looking for ways to boost your heart health, consider algae your ally. Early research shows that taking 4.5 grams per day of blue-green algae by mouth for six weeks reduces high blood pressure in some people with hypertension. Research also suggests that consuming nannochloropsis may boast antioxidant properties that could help lower cholesterol and triglycerides, which could reduce the risk of heart disease.
Algae can play a role in protecting and managing diabetes, too. One study found that obese adults who took 2,000 milligrams of spirulina daily for three months showed an improvement in insulin sensitivity. Further, a daily chlorella supplement was found to improve the fasting blood sugar levels of adults in just four months. (A poor fasting blood sugar level is typically an indication of prediabtes or diabetes.)
It might fortify your immune system.

Research suggests that spirulina contains compounds that act as anti-inflammatory immunomodulators, which could help make your seasonal allergy symptoms a little more bearable. Another study found that healthy adults showed an increase in immune system activity after taking chlorella for eight weeks.
It could give you an energy boost.

In addition to being loaded with minerals, algae is also a good source of B-vitamin. Those nutrients play a key role in turning food into energy, giving you the fuel you need to get through your day with a little bounce in your step.
It can help ward off nutritional deficiencies.

Omega-3s and B-vitamins aren’t the only reason you might want to add algae to your diet. Algae like spirulina, chlorella, and nannochloropsis are rich in minerals like iron, magnesium, zinc, and potassium, which can be tough to get enough of on a given day.
And get this: Algae is also surprisingly high in protein. You’ll get 4 grams from just one tablespoon of spirulina—the same as what you’d find in half a cup of low-fat milk.
Easy ways to add algae to your diet
Up for giving algae a try, but aren’t quite sure how to get started? We get it. Chlorella and spirulina are usually found in powdered form, and they can be a little intimidating if you’ve never used them before.
But there are a bunch of other tasty ways to get your fill of these powerful sea veggies. (Just be sure to get the green light with your doctor first. As with all supplements, algae has the potential to interact with certain medications.)
Here are a few of Smith’s favorite ideas:
Add it to a smoothie: Despite its in-your-face color, algae has a mild flavor that works well with most fruits and veggies. Try adding one or two tablespoons to your other ingredients before blending, Smith recommends.
Mix it into salad dressings: Turn any vinaigrette into a nutritional powerhouse by whisking one to two tablespoons of algae into your favorite homemade dressing.
Sprinkle it over popcorn: Try swapping your usual grated Parmesan for a teaspoon or two of algae.
Rather not use a powered algae? Ask your doctor if an algae capsule or soft gel is right for you. One to consider: iWi's Algae-Based Omega-3 Daily Support, which contains a proprietary strain of nannochloropsis.

And how to easily incorporate it into your diet.
Here’s the deal: Omega-3 fatty acids are an umbrella term used to describe a type of oil that’s rich in polyunsaturated fats (one of the healthy fats) and linked to reduced risk of chronic disease.
There are three types of omega-3s: eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and alpha-linolenic acid (ALA). DHA and EPA come predominantly from algae and, therefore, the fish and seafood that eats the algae. Meanwhile alpha-linolenic acid (ALA) is found in plants and plant-based oils, like flaxseed, canola, and soybean.
Why do I need omega-3s?
Higher levels of DHA and EPA are linked to a reduced risk of chronic disease—including heart disease, diabetes, and some cancers—as well as anxiety and depression (especially in women), and may also help alleviate joint pain and stiffness associated with arthritis. Since omega-3 fatty acids play various roles in cell function and immunity, they contribute in a huge way to virtually all organ systems in your body. The top three benefits include:

ANTI-INFLAMMATORY BENEFITS
Omega-3 fatty acids may help reduce inflammation by increasing cell membrane fluidity, which helps to inhibit proinflammatory pathways that ultimately damage cells, leading to increased chronic disease risk over time.
Research shows that having adequate daily amounts (250mg) of EPA and DHA can be particularly beneficial for those who suffer from rheumatoid arthritis, as they can help with stiffness and pain.

PRENATAL BENEFITS
During pregnancy, women have a higher conversion rate of ALA, EPA, and DHA to meet the demands of fetal brain development. EPA and DHA are crucial for proper development and function, especially for neurological and immune systems as well as the development of fetal retina. They can also help reduce your risk of post-partum depression and depression throughout your lifespan.
Meanwhile, DHA is a major structural component of the central nervous system and the retina.

HEART HEALTH BENEFITS
Recent research found that overweight men and women who were assigned a diet including omega-3 rich salmon twice per week had lower serum cholesterol, which is a key indicator for lowered cardiovascular disease risk.
But while adequate intake of EPA and DHA is shown to help with specific biomarkers linked to heart disease, keep in mind that one piece of salmon won’t “cancel out” heart disease risk if your diet is otherwise filled with loads of sugary beverages, deep-fried and fast-foods, processed meats, sugary cereals, pastries, ice cream…you get the point.
How many omega-3s do I actually need?
The National Academy of Medicine recommends a Dietary Reference Intake for ALA of 1.1g per day for women, while the 2015-2020 Dietary Guidelines for Americans recommends that the general population consume a combined 250mg of EPA and DHA per day.
Your body converts small amounts of ALA to DHA and EPA, but it’s not enough to actually raise blood levels of these fatty acids if you’re not also consuming them in some other form (i.e. via food or supplement).
In fact, a 2018 study found that 100% of the American population aren’t meeting the recommended servings of seafood per week (8-12 oz), while 95% of women between the ages of 15 and 44) don’t meet the recommended 250mg requirement.
That’s why it’s so important to add these crucial nutrients to your diet ASAP. Since your body needs about three weeks to build up a supply of DHA and EPA, adding more food sources and considering supplementation can help you to meet your needs sooner, putting you on the right track to better health.
Where can I find omega-3s?
SEAFOOD
Fish is the most popular source of omega-3s, but as an R.D., I’m often asked whether or not it’s “safe to eat fish” or “how can I get omega-3’s without eating seafood?!” To the former, I say this: Eating a mixed variety of seafood is important for general health and wellbeing, thanks to its vitamin D, lean protein, antioxidants, and differing levels of EPA and DHA.
It’s also (IMO) delicious, but fish isn’t for everyone: It’s gotten a murky rep over the years, due to a prevailing stigma about seafood containing mercury and the impact it has to your health. Some people just simply don’t like the taste or texture of it, and others follow a vegan/vegetarian diet.
Choose seafood that's highest in DHA and EPA, such as:
- Salmon
- Arctic Char
- Sardines
- Sea bass
- Oysters
- Rainbow trout
- Herring
- Mussels
PLANT-BASED FOODS
Regardless of where you fall on the seafood-loving scale, it's still essential that you fill your grocery cart with plant-based sources of omega-3 filled foods.
The highest plant-based sources of ALA are walnuts, chia, flax, and hemp seeds, brussels sprouts, cauliflower, and soybeans. But you should also throw the following foods into the cart, too:
- Nuts and seeds
- Veggies
- Legumes
- Polyunsaturated oils derived from nuts and seeds, like canola, corn, peanut, walnut, avocado, olive, sesame, flaxseed, and chia seeds
SUPPLEMENTS
If you’ve ever heard the term, “You are what you eat,” well, then you may already be familiar with this one! Fish and krill get their omega-3s from the food that they eat—marine plants including various types of algae and seaweed. You can find omega-3 supplements that contain both EPA and DHA as well as ALA in the form of algal, fish, or krill oil.
Never heard of algal oil? It’s the type of vegetarian DHA and EPA derived from—you guessed it—algae. One of the world’s most nutrient-dense plants and the source of long chain omega-3s, certain algae species are now being specifically cultivated for the purpose of creating dietary supplements.
To meet your needs, you'll need to aim for about 1g of total omega-3s (and particularly, 250mg of combined DHA and EPA). Much of the research out there to-date has shown that these levels are beneficial regardless of your current life stage, while consuming seafood in addition to an omega-3 supplement may be an added bonus for long-term heart health and chronic disease risk.
Which omega-3 supplement is right for me?
There’s a good chance you’ve taken fish oil for a spin before, but—like most people— abandoned it the second you experienced that very specific aftertaste or were left feeling nauseated. The beauty of algal oil, on the other hand, is that it’s tasteless, so you’re much less likely to experience that discomfort and nausea-inducing fishy taste.
Another benefit of choosing algal oil-based supplements is that they’re considered vegan, which means that if you are choosing to opt out of seafood (or even if you aren't), you can still meet your needs. Plus, using this DHA/EPA source to make supplements shows promising sustainability benefits and may help to decrease overfishing in the U.S.
While research on algal oil is still ongoing (and more is needed to determine its long-term benefits in decreasing chronic disease risk and for their impact on specific populations) there have been some promising early studies that link the microalga to improved health parameters and biomarkers.

You’ll want to do some research before taking any dietary supplement, but for anyone looking to start, iWi’s Algae Omega-3 is a good option. It’s made from a type of algae called Nannochloropsis, which some small, early research has linked to improving digestion, absorption, and blood levels of EPA. Since it’s made from a plant-based source (and farmed in the U.S. using sustainable growing practices), the supplement provides up to 280mg of EPA and DHA, so you can meet your needs ASAP and mitigate environmental concerns.
Keep in mind that supplements are not evaluated for safety and efficacy by the FDA. So, no matter the supplement source (plant vs. animal/marine), you should always check ingredient labels and speak with your physician before starting a supplement regimen.

I have commitment issues -- with my diet.
Name the diet, and I've tried it. I'm currently a pescatarian with fish as my main protein source. But I've been a carnivore, vegetarian and vegan, too.
Oh, and I dabble in "menu of the future" items such as algae and bugs.
In the last month, I've had algae smoothies, algae protein bars and algae chips. It's not because I'm a particularly adventurous eater or that I love the taste. I actually loathe the mossy flavor of algae.
I eat it because I'm a worry wart when it comes to our environment. We've gotten ourselves into some trouble. Our dining habits are a big part of the problem.
The average American male consumes 100 grams of protein daily -- almost double the necessary amount. This overconsumption isn't sustainable. The United Nations projects food production will need to increase as much as 70% by 2050 to feed an extra 2.5 billion people.
To survive, we need to reinvent the way we farm and eat. Experts say algae could be a possible solution. Unlike most crops, it doesn't require fresh water to flourish. That's a big deal. About 70% of the planet's available fresh water goes toward crops and raising livestock.
Meat uses up a lot of our finite resources, like water and land, not just for the animals but to grow their food, too. But the green slimy stuff that lives in oceans, ponds and aquariums can grow fast, is packed with nutrition and needs next to nothing to grow. It can even grow in a desert.

Several weeks ago, I visited algae farm Green Stream Farms in the sleepy town of Columbus, New Mexico, a stone's throw away from the Mexican border. With a location that feels like you're in the middle of nowhere and a population of 1,600, you'd never expect this is where the food of the future comes from.
But that's where wellness company iWi is growing a strain of algae on a massive scale. The farm has green seas as far as the eye could see. The entire farm is 900 acres -- 98 of which are currently being cultivated -- and operates all year round.
At the farm, I got my hands dirty. I wadded thigh-high in a sea of green algae and reached my hand into a vat of the harvested "green gold," coating it in cold, verdant goop. Feeling bold, I licked the dripping algae off my finger.
It was a far cry from the gross-tasting algae I've had in the past. That's because not all strains of algae smell or taste like pond scum. Some algae I've tried before even turned my tongue black-green. But the farm's fresh algae simply tasted salty and gave me hope people would willingly eat this.

"There are hundreds of thousands of strains of algae in the world and there is a subgroup of those that are stinky and slimy and gross, but there are lots that are not," said Rebecca White, iWi's VP of Operations.
IWi is betting their strain, nannochloropsis, will be next big food trend. The company already sells algae as omega-3 and EPA supplements at the The Vitamin Shoppe and on Amazon. It's now developing algae-based snacks and protein powders.
"The protein we're producing is not going to be green," said CEO Miguel Calatayud, adding its protein powders will be virtually imperceptible when added to other foods. It is "not going to change the flavor."
"[It will be] in every single food that you take on an everyday basis," he added. "Algae is going to be part of a regular food chain for us. It's going to be great thing for all of us and for our planet."
Calatayud said if the world's population grows from 7.5 billion to 10 billion as expected, we'll need to think more seriously about protein alternatives like algae.
"There will not be enough animal protein or other vegetable protein," he said. "There won't be enough arable land, and what's even more important, there won't be enough fresh water."

IWi's strain of algae takes what would otherwise be wasted -- saltwater, desert land and CO2 -- and turns it into something special. Made up of 40% protein, it can produce about seven times the amount of protein as soybeans on the same amount of land. The plant also releases oxygen into the air. (About 50% of the world's oxygen comes from algae).
"There are tons of desert areas all over the world and most of them have brackish water underneath," he said. "What we are building it's 100% sustainable and 100% scalable."
When it comes to actually growing algae, the approach falls into two classes: an open method in an environment like a pond exposed to the elements, or a closed system in a photobioreactor with a more controlled environment. IWi uses an open method by harnessing the power of the sun to feed its algae.
Algae at the farm is grown in long ponds called "raceways," and an engine constantly churns water to make sure the algae is exposed to the sunlight. CO2 and a tiny bit of fertilizer is then pumped into the water to help the algae bloom.

Algae isn't the only protein alternative scientists are tinkering with. Lab-grown meat companies such as Memphis Meats, Beyond Meats and Impossible Foods are working to popularize cultured meats and plant-based meat substitutes. Their products are currently on supermarket shelves and have a sizable following with vegetarians and vegans.
Other meat alternatives include bugs -- especially crickets, largely considered the tastiest insects. I've popped them into my mouth like potato chips. The hardest part is wrapping your brain around eating something you'd usually spray with Raid or squash with a book.
But they don't taste that bad. I've even had some bug-based dishes that were truly delicious. When crickets are ground into flour for protein powder, it's unrecognizable. Form factor matters.
More than 2,000 edible bug species are eaten by 2 billion people worldwide, and for good reason.
"Insects are rich in protein and essential micronutrients, such as iron and zinc," said Dr Matthias Halwart of the United Nations' Food and Agriculture Organization. "They don't need as much space as livestock, emit less greenhouse gases, and have an excellent feed conversion rate."
For example, a pound of feed yields 12 times more edible cricket protein than beef protein, he said.
Perhaps it's only a matter of time before Western countries stop turning up our noses at plated insects and start chowing down.
And algae for dinner may be a long shot for now, but the powerful potential of this tiny super crop can't be ignored.

We had a fascinating conversation with Miguel Calatayud, CEO of Qualitas Health, joins us in a mind-blowing segment about algae. This supercrop can be the solution to one of the biggest problems our world is facing.
Please excuse any typos in this hasty transcript.
Matt Register: Welcome back to Texas Business Radio. Texasbusinessradio.com is the website. 844-814-8144 is our 24 hour call line. Get your calls in, we’re going to get the experts in here to get you the answers to those questions. Jay Curry had to step out for a minute. He’s going to join us here shortly. I’m your host Matt Register and we’re talking about food. Everybody loves food, everybody needs food. Food is a big industry. Food has, drives a lot of the economy and especially here in Texas. There’s some really exciting stuff going on around our food and this segment is no different. You’re really going to enjoy this. We have Miguel Calatayud…
Miguel Calatayud: Calatayud.
Matt Register: Calatayud, I got that correct. Wonderful. Miguel is the CEO of Qualitas Health, with an absolutely fascinating story about a brand new industry that is here in Texas. I think you’re really going to enjoy. Miguel Welcome to the show, Sir.
Miguel Calatayud: Thank you very much Matt. And thank you very much for everybody to give me the chance to talk a little bit about us.
Matt Register: Well, I tell you what, tell me a little bit about Qualitas Health. Because and I got to be honest with you, we started talking and you were telling me about some of the algae that you guys were growing. It certainly didn’t make me hungry but this is going to change the food business as we know it in the world. Right?
Miguel Calatayud: So, very quickly about me and just for everybody to understand why this is so exciting. I was born in Spain and I was lucky to run a food company with my mentor, Javier Viertel, the owner of Viertel. And then I came to the states to do the same thing here. By the time I left, everyday we were growing about 650 million pounds of vegetables. So I’m very familiar with agriculture, worldwide, global company and I really wanted to do something different. I really wanted to participate in a project that would be a breakthrough in the food and nutrition industry. I’m very involved in the health and wellness. And I’m really excited about helping people to eat better and solve some of their nutrition problems that is in the world. And Qualitas was the way to do it. What we do is we grow algae in the desert of Texas; Millennium, Imperial and also in New Mexico and we will keep expanding this all over the world. And what we are basically doing is we are extracting omega 3 and we are attracting protein out of the algae. Which is, after knowing crops, I used to grow peas, for example. Which is what people take as a protein substitute to meat.
Matt Register: Sure.
Miguel Calatayud: And our productivity is about 300 times more than peas, in terms of production of essential amino acids. Which means that our hundred and fifty acres that we currently have on production. We are probably the biggest algae producers in the world. But our 150 acres, which doesn’t sound much.
Matt Register: Sure.
Miguel Calatayud: In, you know, in terms of beans or corn, equals to 45,000 acres of peas in production of essential amino acid. So it is really a breakthrough in the agricultural business, in the food business.
Matt Register: Well, I tell you what, there’s a few, several things in that statement that are quite amazing. OK. One of them is, you’re able to grow this algae in lamd that is otherwise unfarmable. Right?
Miguel Calatayud: Yes.
Matt Register: In the middle of the desert. Correct?
Miguel Calatayud: Absolutely.
Matt Register: You’re able to use brackish water that is unusable for agriculture any way outside of this. Correct?
Miguel Calatayud: Absolutely.
Matt Register: And we were talking during the break. Tell me a little bit about the omega 3. Because, you know, I know people that take the omega 3 oils and there’s a lot of benefits to it. But the fish and shrimp and things that, that most omega 3 is extracted from. Their not the ones that make it. Correct?
Miguel Calatayud: So, this is absolutely right. Many people are familiar with fish oil and krill oil. Which is the, you know, natural source for many people of Omega 3’s. What people don’t know is that fish and krill do not generate omega 3. It is the algae that they eat through their lives. What provides them with the omega 3. So we go directly to the source and we keep the middle fish literally. Right?
Matt Register: I got it. So, so, the omega 3 is being produced by the algae. Right?
Miguel Calatayud: Yes. And the advantage of us is, you know we have an amazing value proposition because we are a hundred percent vegan. Which is, very few can say that. We have full traceability because we are vertically integrated and we control the whole, the whole process. We have the highest bio-availability, which is the absorption rate by the human body, in the whole Omega 3 industry. Because we go directly to the source and we are born and raised in Texas. That is a value proposition. But in addition to that, we have a beautiful, noble cause. We are the new farmers of Texas. We grow algae in the desert. We use nonfarmable land. We use brackish water. We use the sun as the main source of energy and we are 100 percent sustainable and scale-able. Which is, business wise, very interesting to me.
Matt Register: It’s all very interesting. Right? One of the things that we spoke about a minute ago was the, the growth in the human population and the need to increase the amount of protein we produce and essentially the amount of calories. I mean you have more people, you have to produce more calories. Right?
Miguel Calatayud: Yes.
Matt Register: And at some point we’re running out of prime farmland. Right?
Miguel Calatayud: Yes.
Matt Register: Talk to me a little bit about the byproduct. After, after you get done extracting the omega 3’s. That leaves you with a great big pile of protein. Right?
Miguel Calatayud: So, our strain is very unique and our technology also. We have a very unique team, our, I will talk later about the team. We have the best team in the industry, in my opinion. I’m really blessed to be able to work with this group of professionals. But what we do is, over 40 percent of our biomass is pure protein and this protein is very unique also. Because if you compare it with pea protein or other proteins, our protein has the whole essential amino acid chain on it. Which is a very balanced and very high quality protein, comparable to meat or anything else. In addition to that our productivity, as I mentioned before we are 300 times more productive than peas, for example. So that is something that is necessary in this world. We are going to go from seven and a half billion people to 10 billion people by 2050. That means that we need to produce about… because we are eating more and better. We need to produce about 70, 7 0, 70 percent more protein and nutrients in the next 30 years. The seas are hurting, there’s not enough farmable land, there’s not enough fresh water. If you have to choose between a conventional crop and our super crop, you would choose our super crop. Right? But you don’t need to choose, because you can keep growing your normal crop in the farmable land. And we will be able to use non-farmable land and the brackish as water to do this. So this is a breakthrough.
Matt Register: It’s an addition, not a replacement…
Miguel Calatayud: Absolutely
Matt Register: Of that. This is, it sounds to me like this solves a whole lot of problems. Now, you guys have some unique challenges ahead of you. Right? This is, your supplement has gone through all the FDA process and everything else. You have an education to do with people. Right? I mean, this is going to take some time to take off.
Miguel Calatayud: So, we are really, well, it’s already taking, taking off. We are really launching brand with HEB. Almega PL is exclusively in HEB. You can find it in older stores of HEB. HEB is an amazing partner, by the way.
Matt Register: Sure.
Miguel Calatayud: Texas, very well handle company and very professional. So we like this brand. The customers are responding amazingly to that. Because, as we said, it’s the perfect quality product. It’s the best omega 3’s, that you can buy in the market. It is fully sustainable and is coming from Texas. So people are very excited. What we are planning to do is, we will go national by the end of this year with different brands. We are launching a live brand and we are planning to also go international in Q4 or Q1, starting in Australia and Japan. So we have a lot to do, a lot of work to do.
Matt Register: Sure.
Miguel Calatayud: Education awareness, it’s a very important part of what we need to do in the coming months. But we have, as I said, the best partners and the best team in order to make it happen.
Matt Register: Well, it’s remarkable and there’s a tremendous amount of science behind this. This is, you’re going to be hearing a lot more about algae. If, if you haven’t yet, you’re going to get to know this because it certainly solves a lot of problems. And with our problem of figuring out how to feed the world. This, while it may not be the perfect, you know, the one solution. It is certainly going to be a solution. Right? And all done right here out of Texas. We have Miguel Calatayud, who is a CEO of Qualitas Health. Miguel, thank you very much for joining us. This has been fascinating. We are going to have you back by the way. We’ve got a whole lot more to talk about. Miguel what is the easiest way for somebody to learn more about this.
Miguel Calatayud: So, the easiest ways is go online and just click www.Qualitas-health.com. Or go to any of your HEB’s and ask about our algae omega 3. And I do believe that you are going to be surprised about what algae can do for you and for the whole world.
Matt Register: Yeah.
Miguel Calatayud: Thank you very much.
Miguel Calatayud: No doubt. Miguel, thank you very much. Again guys, we got to go take a break. We got to pay some of our own bills. We’ll be back right after this. Talking about food. Don’t go anywhere.
