You may be wondering how we make our algae omega-3 supplements. At iwi, we talk a lot about creating supplements that are sustainably sourced and have little impact on the environment.
If you’re a fan of algae supplements, chances are you’ve already heard about the wonders of Spirulina and Chlorella. Today, we will discuss Nannochloropsis algae, which we use in our algae omega-3 supplements.
Not only do we care about creating environmentally-friendly products that are suited for your health needs, but we also care about nutritional transparency. That means being honest and transparent about the ingredients we incorporate into our products.
If you’re interested in learning more about the algae we use and how we sustainably make our products to benefit you and the global community, then keep reading!
What Is Nannochloropsis Algae?
Nannochloropsis algae is a type of marine microalgae that is similar in some respects to chlorella. Interestingly enough, even though it closely resembles chlorella, the two tiny plants have some important differences.
It is incredibly small, only measuring up to 2 to 5 microns, so a single Nannochloropsis alga is not visible to the naked eye. Nannochloropsis is native to the North Atlantic ocean. Since its habitat is high-salt and high-mineral sea water, this tiny organism adapts easily to the salty underground water found in natural aquifers under certain desert areas. This makes it ideal for large-scale cultivation for food and supplements!
One of our favorite things about Nannochloropsis is how abundant it is.n outdoor farming settings, Nannochloropsis can be harvested up to two times a week, all year long! Contrast that with other vegetables like broccoli which can be harvested once.
What Are Its Benefits and Uses?
In addition to the nutrients present in fresh, brackish, and salt water microalgae like Spirulina and Chlorella, certain marine microalgae such as Nannochloropsis provide EPA and DHA that are key for use in dietary supplements such as iwi's algae omega-3 supplements.
Research shows that Nannochloropsis contains vitamins and antioxidants, along with high levels of the omega-3 fatty acid EPA, which has numerous health benefits.
Other advantages of Nannochloropsis involve high oil yield, short generation times, no agricultural land requirements, reduced freshwater needs, and reduced greenhouse gas emissions during cultivation.
How Is Nannochloropsis Algae Grown?
There are many ways that algae in general can be cultivated. Open ponds, closed bioreactors, with sunlight, with artificial light...let's take a look at the different ways algae can grow:
- Photoautotrophically: From the Greek words "phos" (light), "auto" (self) and "trophe" (food), photoautotrophs are organisms which can make their own energy using sunlight via photosynthesis. This means they always contain chlorophyll, the deep green plant compound needed to produce energy from the sun.
- Heterotrophically: "Hetero" in Greek means "another" or "different," so heterotrophs have to consume something different (like sugars) to obtain their energy vs. creating it themselves.
- Mixotrophically: You may be able to guess now that you've learned the other two types — mixotrophs can consume a "mixed" diet of energy they synthesize themselves from sunlight or from eating other things around them.
Microalgae like Nannochloropsis grow quickly in open ponds or labs. They can also grow in seawater with high yields of lipids. It grows fast which means we can get a great amount of Nannochloropsis without harming the environment.
The best news is that Nannochloropsis algae mainly requires salty water (check — no precious fresh water required), abundant sunlight (check — no energy spent on grow lights), and a few key nutrients in the mix. Compared to other crops, the environmental impact of farming algae is incredibly low.
Because of Nannochloropsis'ability to create its own food through photosynthesis, growing it in open ponds with plenty of sunlight makes great sense. No grow lights are needed, and the algae makes its own energy, so the environmental impact is extremely low.
One type of open-air pond is called a "raceway pond" because the long channels curve at the ends to form a raceway shape. This style of pond can also use just a single, simple paddlewheel (like the kind that would power a boat in Mark Twain's era) to keep the water flowing, which again uses very little energy resources. Ponds of this nature can also be harvested by gravity — no electric pumps required.
Some microalgae can grow heterotrophically with an organic carbon source instead of light. This gets around the issue of light limitation or photoinhibition. The downside is that nutrients and environmental factors often impact cell growth.
One of the problems when cultivating microalgae for lipid production is light intensity reduction in a closed system like a bioreactor. This issue can be partially solved in a mixotrophic operation.Algae which can grow mixotrophically can grow with both an organic carbon source, like glucose, and light. By being able to use light and sugar for growth can lead to better growth and higher cell densities.
All of those methods are suitable for various strains of the more than 70,000 types of algae, but as you read, outdoor pond farming works best for Nannochloropsis, and results in benefits for humans and the planet. This is how we find inspiration: learning about how even the smallest of cells has the power to restructure our way of thinking about sustainability and farming.
How Is Nannochloropsis Algae Harvested?
Now that you have a better understanding of how Nannochloropsis algae are grown, you may be wondering how it is harvested.
When most of us think of harvesting a crop, we may imagine old-fashioned scenes of wheat being cut by hand, or corn being collected by a massive combine with a spinning thresher, shooting corn kernels into a grain bin. Harvesting microalgae looks pretty different, as you might expect!
iwi's algae is harvested by gravity, which allows for the lowest energy requirement. The deep green water is collected, filtered, and concentrated.
Just as traditional farming has evolved from the days of scythes and horse-drawn carts, the world of algae aquaculture is always evolving, too.
And that’s where our core value comes into play: innovation. While there are roadblocks that come from different farming techniques, we also realize that there are more discoveries to be made. The future requires it, so we provide it.
Why Do We Use Nannochloropsis Algae?
We don’t mean to repeat ourselves, but we take time and effort to find ways to make products without harming the environment.
To begin with, algae is immediately more inclusive than fish oil. Many people simply don't enjoy the taste of fish — and especially when it "repeats" (read: burps back) after taking a fish oil supplement.
Far more people choose not to eat fish because they are vegan, or are committed environmentalists. We want everyone to have access to the highest-quality omega-3s!
We also knew algae would be more sustainable since we wouldn’t be contributing to overfishing or using harmful farming techniques.
Specifically, we chose Nannochloropsis algae because it could still provide the benefits in our supplements without having to compromise our morals. This 2018 study shows that marine microalgae like Nannochloropsis provide a far more sustainable solution than fish or krill oil.
