Some Dietary Fats May Ease Premenstrual Syndrome

Taking supplements containing gamma-linolenic acid and a mix of other healthy dietary fats can significantly reduce symptoms of premenstrual syndrome (PMS), according to a study by Brazilian researchers.


Edilberto A. Rocha Filho, MD, of the Federal University of Penambuco School of Medicine, and his colleagues treated 120 women who had experienced a variety of PMS symptoms. The supplements contained either 1 or 2 grams of fats or placebos, and they were taken daily for six months.


Each 1-gram capsule provided 210 mg of gamma-linolenic acid, 175 mg of oleic acid, 250 mg of other polyunsaturated fats, and 20 mg of vitamin E. The 2-gram dosage had twice these amounts.


Women in the study recorded the intensity of 23 PMS symptoms, including anxiety, depression, headache, and water retention. The 1- and 2-gram supplements led to significant improvements after three and six months, with the 2-gram supplement providing the greatest benefits. The placebos led to improvements after three months, but their benefits wore off after six months.


Gamma-linolenic acid is obtained from plant oils, and it is the precursor to prostaglandin E1, a hormone-like substance that has analgesic properties.
