Evening Primrose Oil (EPO) is a rich source of Omega-6 Essential Fatty Acids, Linoleic Acid and Gamma-linolenic Acid (GLA), which the body can only get through diet or supplements. The body converts GLA to a hormone-like substance called Prostaglandin, which keeps the normal body metabolism functioning efficiently and effectively. HealthAid Evening Primrose Oil is the ideal supplement that contributes to the maintenance of healthy skin, flexible joints and all metabolic functions. HealthAid EPO with vitamin E is cold pressed and hermetically sealed in soft gelatin capsules to maintain freshness and purity.
