Strong B-12

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

Thanks for your feedback!

More brain food

This is easy to take. And they now think one of causes of alzheimer is the lack of B-12 in our brains. This is the maximum daily dose. I also read in my researching that too much B-12 causes brain cancer. TWM
