GLA
There has been interest in a particular fatty acid that is found in evening primrose oil, GLA (gamma-linoleic-acid). Some women report relief from PMS symptoms when they take GLA, while others perceive no benefit. Because of the lack of consistent information from scientific studies, the efficacy of evening primrose is uncertain. Source: British Nutrition Foundation

Lycopene

Several studies have been conducted and women have been encouraged to act on the results. Some take large doses which can lead to nerve damage. Recently the Food Standards Agency’s Expert Committee on Vitamins & Minerals advised people to limit intake of B6 from dietary supplements to 10mg/day, unless on medical advice.
