Omega-3 Fatty Acids 2 articles

Omega-3 Fatty Acids are a family of polyunsaturated fats that includes ALA, EPA, and DHA. The family name therefore does not specify one fatty acid: food and supplement comparisons should distinguish the individual omega-3 forms, their source, and the amount of EPA, DHA, or ALA rather than relying on a single total-omega-3 label. Flax, chia, and walnuts are notable sources of the plant omega-3 ALA, while fatty fish, fish oil, and algal oils supply long-chain EPA or DHA in varying proportions.
