Hi Folks. i've posted on here before & got helpful advice. i have ME/CFS & responded very well to Hydroxy/C & Folate when i 'first' supplemented with b12. however, after about 6 months, the response from the b12 rapidly declined. presently it's doing v. little & my symptoms are piling up and dragging me down. it's possibly a case of ''diminishing returns'' or i have developed an auto-immune response to transcobalamine 11. i would, therefore, like to try out one of the 'active' forms of b12: either
1) Adenosylcobalamin or 2)Methylcobalamin. could anyone comment on 1)which one might best suit me. and where i can source it from. i'm in a very low state presently.
