Flax Seed

Flaxseed is a rich source of the omega-3 fatty acid alpha-linolenic acid (ALA) and is high in a class of phytoestrogens known as lignans.

Linseed oil, derived from the seeds, is used in the production of paints, printing inks, linoleum, varnish, and oilcloth. It has the highest level of ALA of any vegetable oil, and food-grade linseed oil is sometimes taken as a nutritional supplement.
