Gamma-linolenic acid is an essential polyunsaturated fatty acid. Polyunsaturated fatty acids (PUFA's) perform diverse biochemistry in most of the cells in our bodies. One group of PUFA's, the omega 6 fatty acids, play a role in the modulation of membrane structure and the formation of prostaglandins. They also control the water impermeability of our skin and possibly the gastro-intestinal tract coupled with the regulation of cholesterol transport and synthesis.

High GLA supplementation may be of use when there is a requirement for higher levels of gamma linolenic acid. One capsule of High GLA (sourced from borage/starflower oil) contains nearly three times as much GLA as that found in an equivalent supplement containing evening primrose oil only.

High GLA is an ideal supplement where a high GLA intake is required, for example, during periods of rapid growth or when the diet is high in saturated fatty acids.
