According to Japanese scientists frequent mood swings characteristic for women appear as a result of inadequate zinc intake.
Scientists insist it is necessary to take 7 milligrams of zinc gluconate daily as a dietary supplement, which is enough to reduce psychological problems manifested through frequent mood swings after a certain period of time.
Japanese scientists came to this conclusion after a 10-week researching program which involved 30 young women. During that time respondents regularly consumed zinc gluconate, and after 10 weeks scientists noted increased zinc level in their blood, which positively affected their mood. Respondents showed decreased feeling of anger, bad mood and depression.
