α-Linolenic acid, also known as alpha-linolenic acid (ALA) (from Greek alpha meaning "first" and linon meaning flax), is an n−3, or omega-3, essential fatty acid.ALA is found in many seeds and oils, including flaxseed, walnuts, chia, hemp, and many common vegetable oils.

Omega 3 is an essential fatty acid that is known to improve heart health, reduce inflammation, and boost cognitive function in dogs. One of the best sources of omega-3 for dogs is through a diet ...
The effect of krill oil, at a lower dose of EPA + DHA (62.8%), was demonstrated to be similar to that of fish oil on blood lipid levels and markers of inflammation in healthy humans. [73] While not an endangered species , krill are a mainstay of the diets of many ocean-based species including whales, causing environmental and scientific ...
The seed oil of Oenothera biennis (evening primrose) is a source of GLA. From GLA, the body forms dihomo-γ-linolenic acid (DGLA). This is one of the body's three sources of eicosanoids (along with AA and EPA.) DGLA is the precursor of the prostaglandin PGH 1, which in turn forms PGE 1 and the thromboxane TXA 1.
Flax seeds produce a vegetable oil known as flax seed oil or linseed oil, which is one of the oldest commercial oils. It is an edible oil obtained by expeller pressing and sometimes followed by solvent extraction. Solvent-processed flax seed oil has been used for many centuries as a drying oil in painting and varnishing. [29]
Linseed oil is an edible oil in demand as a dietary supplement, as a source of α-linolenic acid, an omega-3 fatty acid. In parts of Europe, it is traditionally eaten with potatoes and quark. [citation needed] Food-grade flaxseed oil is cold-pressed, obtained without solvent extraction, in the absence of oxygen, and marketed as edible flaxseed oil.
It has been claimed that among hunter-gatherer populations, omega-6 fats and omega-3 fats are typically consumed in roughly a 1:1 ratio. [3] [4] [better source needed] At one extreme of the spectrum of hunter-gatherer diets, the Greenland Inuit, prior to the late Twentieth Century, consumed a diet in which omega-6s and omega-3s were consumed in a 1:2 ratio, thanks to a diet rich in cold-water ...
