I have been looking at everything I can see about methylcobalamin for years. I know of absolutely no reason to fear harm if you took dozens of those 1000 mcg methylcobalamins every day. A possibility of help, yes. Danger, no.

It's amazing how ill, even near death, some can be and have a good lab report. I was literally dying for lack of B12, and my CBC results were smack down the middle.
