GLA 130 Primrose Oil provides a highly-concentrated amount of gamma-linolenic acid and linoleic acid which are necessary for the support of normal cell structure and body function. Essential fatty acids are precursors for the series 1 prostaglandins which are needed for T-lymphocyte function and for improving kidney function. Deficiency in essential fatty acids may cause hardening of the arteries and heart, leading to cardiovascular disease. GLA 130 Primrose Oil is indicated for conditions associated with the cardiovascular system, including arteriosclerosis, high and low blood pressure, elevated cholesterol levels and vascular fragility; for premenstrual symptoms, and rheumatoid arthritis; and for skin disorders such as acne, psoriasis and eczema.
