How does fish oil differ from flax seed oil?
Flax seed oil belongs to a family of unsaturated fats called Omega-3 fatty acids. Flax seed oil is an excellent source of alpha-linolenic acid. Alpha-linolenic aid is one of the two essential fatty acids our bodies need and therefore must be obtained through either diet or supplementation. The American diet tends to lack in this essential nutrient because it is not widely available in the food supply (good sources include the oil derived from flax seeds and walnuts).
