I was amazed to discover that zinc deficiency affects almost 1 in 3 persons globally. Mood swings are one of the most commonly occurring symptoms of mild zinc deficiency.

Japanese researchers at Daiguku Junior College and Seitoku University seeking to test the impact zinc supplements could have on mood, 30 young women and placed them randomly into 2 different groups-to receive either multi-vitamins and zinc plus multivitamins for ten weeks. The women were given 7 milligrams of zinc gluconate.

The multivitamins were given to prevent other vitamin deficiencies. It provided half of the recommended dietary allowances of vitamins A, D, B1, B2, B6, B12, folic acid and niacin by the Japanese government.

Upon the study's completion, only the women taking zinc gluconate demonstrated reductions in depression and anger. Their blood levels also increased significantly.

Interestingly animal studies have found that only zinc deficient female animals experienced increased aggression, and this new research seems to support the anger reducing impact in women proceeding zinc supplementations noted the researchers.

"Our results suggest that zinc supplementation may be effective in reducing anger and depression," they concluded.

This study was reported in the European Journal of Clinical Nutrition. "Although our findings are preliminary and should be interpreted with caution, they may prompt further investigations to evaluate the relationship between zinc nutrition and mood states, in women.
