Gamma Linolenic Acid, GLA
Gamma Linolenic Acid is an omega-6 essential fatty acid found primarily in plant-based oils, including evening primrose oil (EPO), black currant seed oil, and borage oil.
For optimum health, the ratio of omega-6 to omega-3 fatty acids should be between 1:1 and 4:1. The typical North American and Israeli diets are usually in the range of 11:1 to 30:1. This imbalance contributes to the development of long-term diseases such as heart disease, cancer, asthma, arthritis, and depression as well as, possibly, increased risk of infection.
