Your body doesn't store vitamin B so make sure you are getting your daily intake.
B-complex vitamins (folic acid, B-6 and B-12) in general, help promote healthy skin , eye, hair, nerve, liver and muscle tone in the gastrointestinal tract. The body cannot store B vitamins and washes them out of the body daily via the kidneys and perspiration. B vitamins work best together. Recently, research has focused on the use of vitamins B-6, B-12 and folic acid and their relationship to homocysteine levels. Homocysteine is an intermediate compound in the conversion of the amino acid methionine to cysteine. Researchers are evaluating the adverse effects that elevated homocysteine levels have on the cardiovascular system.
