Ah yes. Thank you for the validation.

When I was here some time back, I was shot down for mentioning this B12 cohort in PN therapy. Remember? I was told "B1 and only B1 all the way, baby." No. I also did my research, as I have no plans of being a cripple. Now everybody and every snake oiler is selling the B12 hypothesis. Haha. No loneliness is there, in being avant garde.

However, B12 will be of limited use, unless it is specifically indicated. I mean, get homocysteine (HCY) level and methylmalonic acid (MMA) levels checked, else false Puck the Phlebotomist is proven to be.

Also, if you are taking high B9, (folate/folic acid) you will mask B12 deficiency - it wont show. BUT you will continue to worsen your condition -- IFF B12 is indicated as a reason for it.

But, please allow me to post about my recent findings elsewhere, for the good of whoever may benefit.
