After reading this yesterday I bought some "Super Vitamin B complex w/ b-12" from Schiff.
It has niacinamide, 50mg per tablet, as well as many other B's, biotin, pantothenic acid, dicalcium phosphate, d-calcium pantothenate, phosphorus, choline Bitartrate, inositol, paba, & L-Methionine!
Wow, what a suppliment, half off, I paid $8.00. It's yeast free. Anyways, so far I've taken 2 tablets and I can feel the candida melt away quickly in my mouth/tongue. It's not completely gone, but there's a big difference. I just ate some pasta, which should stir up the candida, but instead, my mouth feels protected. The reaction is far lessened. I'm going to take much more after looking up toxicities & see what happens, but the main thing is that SO FAR, the niacimanide sure seems to have made a big difference.
