Protect Your Heart

Vitamin B12 plays an essential role with folic acid and other B vitamins in a series of biochemical reactions called methylation. Methylation is needed to replicate genes and regulate their activity, protect against cardiovascular diseases, and make neurotransmitters and phospholipids. Low levels of vitamin B12 lead to increases in blood levels of methylmalonic acid, which may boost the risk of heart disease, stroke, and Alzheimer's disease. To protect yourself, take a supplement containing vitamin B12, vitamin B6, and folic acid.
