Health News: Vitamin B6 and B12 Levels Linked to Depression

A new epidemiological study showed that low levels of vitamin B12 are linked to the increased risk of depression. While the findings are a connection, the study did not show that increased levels of the vitamin would reduce the likelihood of depression.

Researchers also did not find any association between depression scores when they considered a specific form of the gene that codes for the methylenetetrahydrofolate reductase (MTHFR), an enzyme involved in folate metabolism.

Other studies, such as the one published in International Journal of Geriatric Psychiatry, found that vitamins B6 and B12 supplements, taken daily, are associated with a 30-percent reduction in levels of the amino acid homocysteine, and improved mental tests including global cognition and episodic memory.
