Flaxseed and flaxseed oil
By Mayo Clinic Staff
Flaxseed (Linum usitatissimum) and flaxseed oil, which comes from flaxseed, are rich sources of the essential fatty acid alpha-linolenic acid — a heart-healthy omega-3 fatty acid. Flaxseed is high in soluble fiber and in lignans, which contain phytoestrogens. Similar to the hormone estrogen, phytoestrogens might have anti-cancer properties. Flaxseed oil doesn't have these phytoestrogens.
Flaxseed can be used whole or crushed, or in a powder form as meal or flour. Flaxseed oil is available in liquid and capsule form.
People use flaxseed and flaxseed oil to reduce cholesterol and blood sugar and treat digestive conditions. Some people also take flaxseed to treat inflammatory diseases.
