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 the diet or supplements. The body converts GLA to a hormone-like substance called Prostaglandin. This helps maintain the body?s metabolism, to keep it functioning efficiently and effectively. EPO is the ideal supplement to help maintain healthy skin, flexible joints and all metabolic functions. HealthAid EPO with Vitamin E is cold pressed and hermetically sealed in a soft vegetarian capsule to maintain freshness and purity.
