QUICK ANSWER

Algae Omega-3 EPA/DHA: Heart · brain · inflammation (vegan). Plant-based EPA/DHA from algae, the same omega-3s as fish oil, since fish get them from algae in the first place. Standard dose 500 mg EPA+DHA, taken in the morning, about $28/month. Evidence rating: strong evidence.

What is Algae Omega-3 EPA/DHA?

Algae oil is the original source of EPA and DHA, fish only contain these long-chain omega-3s because they eat algae or other fish that ate algae. Direct algae supplements provide the same omega-3s without involving fish, making them the cleanest option for vegans, vegetarians, and people with fish or shellfish allergies. They are also typically free of the heavy-metal and PCB contamination concerns associated with ocean-sourced products. Ovega-3 and Nordic Naturals' algae line each provide 500-700 mg of combined EPA+DHA per serving. Daily intake of at least 500 mg of EPA+DHA is associated with cardiovascular and cognitive benefits.
