What meds are available for B12 deficiency? What are side affect of each? (injectible meds my B12 levels were 169). Thanks
Methylcobalamin. Injectable B12 is the surest way to increase your B12 levels. Injections are usually administered weekly, but I occasionally prescribe them on a daily basis. Methylcobalamin is the most bio-available form of b12, but is slightly more expensive than the traditional cyancobalamin form. Sublingual methylcobalamin is the next most effective way to restore tissue B12 levels. No adverse effects.
