ALA (alpha-linolenic acid) is a basic omega-3 fat that can be converted in the body to the other omega-3s the body needs. ALA occurs in small amounts in beans, vegetables and fruits, and this should be all the body needs. If more is desired, it is also found in walnuts, soy products and, in high concentration, flax seeds and flax oil. If these are used, there is no need for more than minimal amounts. If you are looking for more, for whatever reason, health food stores sell vegan omega-3 supplements.
