The whole methyl mercury, methylcobalamin, methylation, etc., thing is pretty complex. I'm not surprised there's confusion.

If I were attempting to cope with a metal or other toxin, I would take the methylcobalamin for that reason alone. And, of course, if one still is suspicious, the methylcobalamin can be swallowed.

And, mercury can interfere with methylcobalamin. Makes it even more necessary.

If anyone has anything credible to the contrary, I would love to see it. Always willing to learn.
