Vitamin B12 and Depression

Dr Kathi J. Kemper has reported in her book "Mental Health, Naturally" that Vitamin B12 is essential for healthy function of nerve cells. Without enough B12 homocysteine levels can build up and contribute to heart disease and mood problems. Vitamin B12 is vital for making many of the chemicals which the brain uses for internal communication, neurotransmitters. Vitamin B12 deficiency causes memory loss, disorientation, dementia, psychosis, and mood problems. There is a strong link between low B12 levels and depression. Good dietary sorces of B12 are fish, shellfish, meats, and dairy products.
