An oil pressed from flaxseeds, rich in alpha-linolenic acid (ALA), a plant-based omega-3 fatty acid.
Why it’s used
Taken to add omega-3 fatty acids to the diet, particularly by people who don't eat fish, and sometimes for general cardiovascular support.
What the evidence is for
contributing omega-3 (ALA) intake.
What the evidence says
NIH ODS notes that ALA is an essential fatty acid the body needs from diet, but it converts to the longer-chain omega-3s EPA and DHA only in small amounts. Evidence for cardiovascular benefit from ALA specifically (as opposed to fish-derived EPA/DHA) is weaker and less consistent than for fish oil.
Dose studied
1.1–1.6 g — adequate intake (AI) for ALA, adults, per NIH ODS.
Context
NIH ODS lists an adequate intake (not an RDA) for ALA of about 1.6 g/day for adult men and 1.1 g/day for adult women, based on typical dietary patterns rather than a treatment dose.
Rumors
