I am super happy with this

Super happy with this! I chose it because it’s vegan — and leaving the fish alone is a win-win. Delivery was on time, customer service is fast and friendly, and I’ve now added the plankton capsules to my subscription. Very excited about those!

Product works well

filled star filled star filled star filled star filled star

The product works well and I haven’t had any side effects, similar to another algae-based vegan product I used before. I switched to this brand because it’s grown in the Netherlands rather than harvested from nature. It’s also a bit more affordable than my previous brand.

"More people and too few fish"

Seventy percent of the world’s population doesn’t get the omega-3 they need. And if everyone were to rely on fish as their source, there simply wouldn’t be enough fish in the ocean. According to scientists at NTNU — the Norwegian University of Science and Technology.

Omega-3, good for your heart, eyes and brain.

The Health Council recommends 200 mg of omega-3 daily, but research shows that only 11.4% of Dutch people achieve this.

The dark side of omega-3 from fish

Every year, around 17 billion kilos of fish are caught for omega-3, mainly for fish oil capsules. Did you know that a single fish oil capsule can contain up to 30 anchovies? This puts enormous pressure on our oceans, while fish are just the middleman. Algae are the original source of omega-3: 100% plant-based and fish-free.

30 anchovies for one capsule

For one jar of omega-3, around 30 anchovies are used, a direct contribution to overfishing.

Heated, pressed, deodorized

Anchovies are ground and heated, resulting in an oil with a strong odor and loss of purity.

Not only anchovies die

Alongside anchovies, plankton, juvenile fish and many other marine organisms are impacted by industrial fishing practices.

Why fish? Omega-3 comes from algae.

Fish don't make omega-3—they get it from algae, so you might as well go straight to the source, farmed on the mainland.

Collapsible content

Why omega-3 fatty acids?

Omega-3 fats are polyunsaturated fatty acids. Scientific research shows that at least 250mg omega-3 is good for your heart, brain and eyes (health claims approved by the EFSA).

Why algae oil instead of fish oil?

Algal oil is a plant-based alternative to fish oil. Fish get their omega-3 from algae. By using algal oil, you get omega-3 straight from the source, without the need for fish. Good for you and better for the oceans.

How much omega-3 do I need per day?

The Health Council recommends that adults consume 200 mg of omega-3 per day from fish. If you eat little or no oily fish, one capsule of our algae oil contains 250 mg DHA and 125 mg EPA, making it a practical plant-based option.

When is the best time to take omega-3?

We recommend 1 capsule per day during or just after a meal.

Is the omega-3 free from allergens?

Yes, it is free from allergens.

Is omega-3 safe to take during pregnancy/breastfeeding?

Yes, it is safe to take during pregnancy and breastfeeding.

What is the Totox value of the algae oil?

Our algae oil has consistently shown a Totox value below 5. This very low value indicates freshness and minimal oxidation.

What are the ingredients of our omega-3?

Oil from the microalgae Schizochytrium sp., high oleic sunflower oil,
d-alpha-tocopherol, antioxidants: rosemary extract, mixed tocopherols, ascorbyl palmitate. Capsule: hydroxypropyl starch; humectant: glycerol; gelling agent: carrageenan; purified water.

Here is some more context on the ingredients:

  • Oil from the microalgae Schizochytrium sp: This is the active ingredient: the source of DHA and EPA, the omega-3 fatty acids that the supplement is all about.
  • Sunflower oil: Present as a carrier oil, in the minimum required amount of approximately 10%. Its contribution to your total omega-6 intake is therefore small, especially in proportion to the amount of omega-3 you get from the supplement.
  • D-alpha-tocopherol, rosemary extract, mixed tocopherols, and ascorbyl palmitate: Omega-3 fatty acids are susceptible to oxidation, which can quickly degrade quality and shelf life. These four ingredients are antioxidants that protect the oil. D-alpha-tocopherol is simply a natural form of vitamin E, and ascorbyl palmitate is a fat-soluble form of vitamin C. Without this protection, the omega-3 would quickly degrade.
  • Hydroxypropyl starch, glycerol, carrageenan, and purified water: These are the four ingredients of the capsule itself. They make the softgel possible, not the supplement.

Does omega-3 have side effects?

Omega 3 is generally well-tolerated. Some people experience mild stomach or intestinal complaints at higher doses, such as bloating, nausea, or belching.

What foods contain omega-3?

Omega-3 is found in fatty fish, among other things, but also in algae. Algae are the original source of EPA and DHA. Fish consume these fatty acids through their diet, which is why they contain omega-3.

What does omega-3 do to your body?

Omega-3 fatty acids play a role in various processes in the body. With a daily intake of 250mg EPA and DHA, these fatty acids contribute to the normal function of the heart. DHA also contributes to the maintenance of normal brain function and normal vision.
