B vitamins play important roles in nearly all of the physiological systems in the body. Some of the key supportive roles include nutrient and energy metabolism; as well as the production of DNA, hemoglobin, neurotransmitters, and hormones. Optimal levels of B vitamins have been associated with cellular, cardiovascular, neurological, and psychological health. B vitamins are essential to basal mitochondrial function as metabolic coenzymes, playing a key role in energy production and nutrient metabolism. B vitamins also play a critical role in promoting DNA synthesis and healthy methylation. Methylation is a key regulator of genetic expression and cellular function. Healthy methylation is vital for cellular health, DNA synthesis, hormone, neurotransmitter production, and energy metabolism. B vitamins act as cofactors and methyl donors in a variety of key biochemical reactions occurring in blood cells, neurons, the vasculature, and many other tissues.
