Commonly Found In

Dietary supplements, some fortified plant milks, infant formula, some fortified cereals.

Vegan Alternative

Algal oil-based DHA/EPA supplements. Look for 'algae-derived' or brands like Testa, Nuzest, and Nordic Naturals Algae Omega.

Additional Notes

ALA (found in flaxseed, chia seeds, walnuts) is always vegan but converts to DHA/EPA inefficiently. For direct DHA/EPA, algal oil is the only vegan source. Most fish oil supplements can be replaced with algal oil. Some brands specifically market vegan omega-3 using algal oil.
