There is little difference between them as they are both converted to cob(II)alamin once they enter the cell. From that point on, they are identical. b12science.com/B12Science/D...

Some people (including me) have a bad reaction to methylcobalamin.

Okay thanks.

What us the bad reaction some have (including you) please to Merhylcobalamin

I've tried injecting methylcobalamin once. Quite quickly I just started to feel 'wrong'. It's difficult to describe exactly why I felt wrong. I was agitated, irritable, twitchy. It felt a bit like nicotine withdrawal (but 100 times worse) and a bit like the time I took an antipsychotic (as a volunteer in a trial).

Both of those involve dopamine and I suspect that there may be some interaction between methylcobalamin, dopamine and the enzyme catechol O-methyl transferase (COMT).

Okay Thank you. You described it well.

At the time I bought theses tablets I didnt even know there were different sorts.

I'll definitely stick to hydroxocobalamin injections.
