Very powerful.

Thanks for your feedback!

Great value

Posted by iHerb Customer on Aug 10, 2017 | Verified Purchase

This is a very large dose, which I need at 72 years old. Fantastic value for the price and super fast posting to Australia. We have very high taxes on supplements here and iHerb prices in the US are so much better. Very happy with product and service.

Thanks for your feedback!

Strong B-12

I like the small tablets that dissolve quickly. Affordable, strong and bioavailable methylcobalamin.

Thanks for your feedback!
