    Vitamin B12 Methylcobalamin - 5,000 MCG (60 Chewable

    Natural Factors® Methylcobalamin B12 is active immediately upon absorption, while other forms (e.g. cyanocobalamin) must be converted to methylcobalamin in a two step process. Methylcobalamin demonstrates exceptional activity in areas where other forms are simply not active.

    For people with B12 deficiencies it is popular to have injectable vitamin B12, however, research supports that oral administration of an appropriate dosage has been shown to produce as good of results as injectable preparations in treating vitamin B12 deficiency.

    In people with low levels of B12, supplementation is very effective in improving energy levels and restoring mental function. B12 supplementation is recommended for vegetarians and those suffering from B12 deficiency. Check with your doctor of health professional on what is the best form and potency for you.
