Beneficial effects of melatonin-magnesium supplementation in women with polycystic ovary syndrome (PCOS)

This randomized double-blind, placebo-controlled trial was conducted on 84 women (age 18-40 years) with polycystic ovary syndrome (PCOS) receiving magnesium (250 mg), melatonin (6 mg), magnesium plus melatonin, or placebo for 8 weeks.

Results show that magnesium-melatonin co-supplementation resulted in more reductions in hirsutism (stiff or dark body hair, appearing on the body where women don’t commonly have hair [face, chest, abdomen…]) compared with other groups (p < 0.001). Serum levels of TNF-alpha declined significantly in the melatonin and co-supplementation groups compared to baseline (p < 0.05). Also, magnesium plus melatonin was associated with higher increase in total antioxidant capacity levels, as compared to the other treatment groups (p = 0.001).

In conclusion there is a favorable effect of co-supplementation of magnesium and melatonin in women with PCOS on hirsutism, inflammation and oxidative stress levels.
