What is GLA?
Gamma-Linolenic acid is an omega-6 fatty acid that exists primarily in plant fats.GLA is a precursor of prostaglandin E1, which has a role in regulation of immune system function. It should not be confused with alpha-linolenic acid which is the omega-3 fatty acid found in flax seed. It is essential to human health but cannot be made in the body. For this reason, they must be obtained from food.GLA is found in primrose oil, blackcurrant seed oil, borage oil, hemp seed oil, fungal oils and spirulina. Each contains varying amounts of the fatty acid, with borage oil usually being the most heavily concentrated form. All are widely available in pharmacies, health food stores, or online shops.
