Hello everyone. My b12 was low so I starting taking Methyl b12 . Every time I take it I get the following symptoms; depression, very irritable, hopeless and depressed, and I don't know how to exactly to explain this, but a general feeling of 'heaviness,' as if gravity is pulling on me twice as hard (weird I know).

The higher the dose, the quicker the symptoms will appear and the more severe.

I have only read of a handful of others reacting this way to Methyl b12 but I have yet to hear an explanation as to what is going on.

I do not have this issue when taking cynacobalamin, even with large doses.

I am not taking any other medications or herbs.

I would greatly appreciate any help on solving this riddle as well as some good advice.

Thanks,

Shane
