Sotya Evening Primrose is a dietary supplement primarily used to control various allergies and improve blood circulation. It is notable for its high concentration of essential fatty acids, particularly gamma-linolenic acid (GLA), which is essential for the proper production of prostaglandins. A lack of GLA can lead to several issues, including dry skin. Moreover, evening primrose oil helps regulate estrogen and progesterone levels, relieving symptoms of premenstrual syndrome. It is recommended to take between 2 and 4 capsules daily.
