Algal DHA (vegan omega-3)

Brain health · Pregnancy · Vegan omega-3

Tier 2 — Promising

What it is

The primary structural omega-3 fat in the brain and retina, sourced from microalgae — the same organisms fish obtain it from. Molecularly identical to DHA from fish oil but suitable for vegans, and typically free of mercury, PCBs, and other marine contaminants. Standard doses are 200–500 mg DHA per day, with 300 mg recommended during pregnancy for fetal neural and retinal development. Some algal products also deliver modest EPA; vegans relying on ALA from flax or chia cannot count on meaningful EPA/DHA conversion.
