it depends on why you are taking it. if it is for b12 deficiency then you take vitamin b12 but with a doctor's guidance to monitor blood levels. if you are taking it for high blood levels of homocysteine or to prevent age-related macular degeneration then you take a combination of b12 folic acid and pyridoxine. for more information on dosing side effects and interactions see this link.
is frolic acid necessary when taking vitamin b12 1000 methylcobalamin daily. i currently take 1000 mcg b12 methylcobalamin daily now i'm reading you should combine it w/ frolic acid? is it necessary to add?
