Frequently asked

FAQ

Is there a vegan source of EPA and DHA?

Yes, algal oil is a direct vegan source of both EPA and DHA. It is derived from marine microalgae, which is the original source of these fatty acids that fish consume in their food chain.

Why can't I just take flaxseed oil for EPA/DHA?

Flaxseed oil contains the omega-3 fatty acid ALA (alpha-linolenic acid). While the body can convert ALA into EPA and DHA, the conversion rate is often very low and inefficient, making a direct source like algal oil more reliable for vegans.
