Flax Seed-Primrose Oil provides both omega-6 and omega-3 essential fatty acids EFA?s . EFA?s act as precursors to molecules such as prostaglandins, thromboxanes and leukotrienes which help regulate cellular function. EFA?s have been shown to play a role in blood pressure maintenance, immune system balance, sustaining healthy skin and providing nutritional support during women?s cycles. Flaxseed oil, a rich vegetable source of alpha linolenic acid ALA , and evening primrose oil, a natural source of gamma linolenic acid GLA , provide a potent combination of EFA?s.
