    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.

    Methylcobalamin (vitamin 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. B12 supplementation is recommended for vegetarians and those with B12 deficiency. It helps form red blood cells, prevents vitamin B12 deficiency and helps maintain good health.

    In people with low levels of B12, supplementation is very effective in improving energy levels and restoring mental function.

    Check with your doctor or health professional on what is the best form and potency for you.

    Good Stuff

    Posted by iHerb Customer on Jan 08, 2018 | Verified Purchase

    We love our B 12 , We take it daily

    Thanks for your feedback!

    I feel better!

    Posted by iHerb Customer on Nov 22, 2017 | Verified Purchase

    I think this product helps with energy levels and overall brilliance. I figure as long as I'm taking B12 and it is water-soluble, I should take the highest strength (5000). Tablets dissolve easily and no taste.

    Thanks for your feedback!

    Better than injections

    Posted by iHerb Customer on Nov 17, 2017 | Verified Purchase

    My girlfriend had very low B12 levels on her blood tests, and after a week of taking these daily, her levels were up to mid- normal. I thought only injections could do that, but these really work. Now I will stick to these, no more injections.

    Thanks for your feedback!

    dissolves fast and very effective

    Cant buy this strength in Australian Chemist. Much more convenient than having injections weekly.
