excellent question jinx.
I was told I had a b12 deficiency and was given a prescription for b12 injections and am suppose to give myself shots but I haven't done it yet because all of the people saying b12 methylates mercury so I haven't done it. I'm afraid it would make me worse.
It would be great if someone could explain this in laymen terms so I can understand better. Cutler's book is very confusing to me.
Thanks
