Essential fatty acids are extremely important nutrients for health. EFAs are present in every healthy cell in the body, and are critical for the normal growth and functioning of the cells, muscles, nerves, and organs. Deficiencies of EFAs are linked to a variety of health problems.  Omega 3 EFAs are involved in many different body processes, including their role in maintaining cardiovascular system health, joint health, immune and nervous system health.  Omega 6 EFAs are generally necessary for skin and hair growth, regulating metabolism, promoting transport of fatty acids from the liver to the tissues and maintaining reproductive performance. Omega 9 EFAs are known to be essential for normal metabolism.
