The B vitamins are fundamental for whole body health. They are involved in a number of basic cell repair processes, detoxification pathways, and production of neurotransmitters. B6 is especially important for brain health because of it’s co-factor role in converting a number of molecules to their respective neurotransmitters (serotonin, GABA, dopamine, norepinephrine, and epinephrin). B12, also known as cobalamin, is a vitamin that is important in metabolism, DNA synthesis and regulation, and overall energy production. High B12 levels have shown to have neuroprotective affects against brain atrophy associated with Alzheimers. Vitamin B12 deficiencies can cause symptoms such as fatigue, depression, poor memory and even cause symptoms of mania and psychosis. Folic acid, also known as B9, is fundamental for numerous processes in the body. It cannot be synthesized by the body so adequate intake through food is essential. Folic acid is needed for cell reproduction and synthesis, repair and methylation of DNA. There is a complex relationship between B12, folic acid and Iron. If proper ratios of the 3 aren’t maintained, one can mask a deficiency in another. Niacin (B3) and Riboflavin (B2) are also important B vitamins. Deficiencies in any of the B vitamins can result in fatigue, cognitive impairment and a number of mood disorders and mental illness symptoms.
