Hi all,

B12 has been shown safe, even in the cyanocobalamin (least efficient) form, in 2000-mcg-per-day doses for many decades.

Methylcobalamin is even better, and will help some who cannot be helped by cyanocobalamin. I would have no qualms about taking several 5000 mcg methylcobalamin tablets at once. In fact, there is evidence that a small minority of people need that.

I hope everyone, who has not already, will read my website. It is non-commercial and will not take a long time to explore completely.
