Could someone elaborate, wiki version? I've read this thread and vitamin thread as well. Confused a little, sorry.
Should you take Benfotiamine AND a B-complex AND B-12?

Currently taking - Krill oil, Mutli-vitamin, and diet improvements with juicing. Would like to maximize with adding:
Benfotiamine
R-lipoic acid or alpha lipoic (maybe)
Vit D supplement

Thanks!
