Omega-3: Fish, Krill or Algae? Source Decides

Omega-3 status turns entirely on the source. Fish oil and krill oil are animal-derived, placing them outside vegan and, as marine-animal products, outside vegetarian claims. Algal oil, grown from microalgae, and ALA from flax or chia are plant- and microbe-based and compatible with both. The finished supplement label states EPA and DHA content but not always the source, which is what a review confirms.
