Efamarine is a unique mixture of Efamol Evening Primrose Oil & fish body oil from cold salt water fish. It also contains Vitamin E as an antioxidant. The unique combination of Evening Primrose Oil & fish oil provides a specific ratio of Omega-6 & Omega-3 fatty acids. That optimizes the bodies ability to make a potent & highly beneficial substance called Prostaglandin E1 (PGE1). PGE1 improves cardiovascular function & is a strong anti-inflammatory making it useful to reduce symptoms of rheumatoid arthritis. As well there is a close relationship between fatty acid metabolism & the immune response. Fatty acids help the bodys natural defense mechanisms effectively combat viral infections & have been used to help manage symptoms of immunological conditions such as Chronic Fatigue Syndrome & Multiple Sclerosis.
