Essential fatty acids (EFAs)

unsaturated fatty acids which cannot be synthesized by the body and are used as the starting point for the biosynthesis of necessary metabolic and hormonal chemicals.

Fats our bodies can't make, so we must obtain them through our diets. These fats (which include linoleic and linolenic acid) are very important to hormone production, as well as cellular synthesis and integrity. Good sources of these fats arc flaxseed oil and safflower oil
