Omega-3 from algae – what you can learn from fish


Fish have always known: algae are healthy. They have been feeding on aquatic plants for millions of years. Why? Because they contain valuable omega-3.

In the beginning there were algae

Billions of years ago, microalgae and sea plankton were among the first living things on Earth. It developed itself lives underwater and on land. Even today, the blue whale – after all the largest living organism on earth – feeds on microalgae, among other things. Algae contain many nutrients to grow big and strong. Some microalgae are particularly convincing due to their high content of vegan omega-3 fatty acids.

Omega-3 from algae

Microalgae are not only the well-known Spirulina and Chlorella algae, but also the Schizochytrium algae. This algae is produced without light and feeds on plant residues. To ensure that it does grow, the algae itself synthesizes large amounts of the vegetable omega-3 fatty acids DHA and EPA .

Omega 3 algae provide food for fish

Most of the fish mainly live on (micro) algae. The omega-3 from algae is essential for the fish to survive . And the reason for their premature death. Because its high omega-3 content makes fatty fish a favorite dish of athletes and health-conscious people.

Essential for health

Humans need omega-3. Omega-3 fats belong to the healthy polyunsaturated fats . We can only produce DHA and EPA ourselves if we have enough of the essential alpha linolenic acid. But even then, the synthesized amounts of DHA and EPA are often so small that they cannot develop their health-promoting effects.

DHA and EPA are essential for the heart, brain and eyes. And that is why it is important to consume enough of these fatty acids in the long term. Omega-3 straight from algae is vegan, environmentally friendly and provides you with reliable DHA and EPA.

Omega-3 from algae – an ethical question

Environmental crisis

Overfishing of the seas is just as well known as the harsh conditions under which farmed fish are often kept. But that doesn’t mean you can’t eat fish. There are plenty of certified and sustainably caught fish.

But dealing responsibly with the environmental challenges of our time requires careful consumption. This means that you choose high-quality foods, that you make conscious choices and that you do not eat fish every day . With this in mind, omega-3 fish oil based capsules are also not a sensible solution.

Of course. Environmentally friendly. Vegan.

Omega-3 from algae is environmentally friendly and vegan. The value chain is shortened by removing the intermediate step “fish”. With omega-3 from algae you protect sustainable ecosystems and – almost by accident – you also do something good for yourself, because omega-3 from algae is the most natural way to take in DHA and EPA.

Without additions

Algae, which provide omega-3, are usually grown in aquaculture. Here, the water quality can be naturally optimized so that the nutritional content of the vegan omega-3 fats is optimal. The quality of omega-3 from sustainable algae is therefore easier to control than that of fish.

For vegan omega-3 from algae, the oil is usually extracted from the algae and packed in – in the best case vegetable – capsules.

Edible algae and microalgae

And then there are also algae to eat. Nori, wakame, dulse and sea spaghetti are probably the best known algae-based food items. They are green, bluish or dark, look like you think algae look like, and are increasingly part of the top gastronomy . Their nutritional values ​​impress with the high protein and fiber content and the low calorie count .


  • Algae are the most natural and oldest sources of omega-3 in the world.
  • Algae oil in capsule form is the most sustainable way to take in DHA and EPA.
  • With vegan omega-3 from algae you are doing yourself, the environment and the fish a great favor.
