Most of the studies used 600mg a day or more of ALA.(alpha lipoic acid) ALA is 1/2 inert and that inert portion doesn't work. The r-lipoic is the concentrated active portion of ALA. R-lipoic is newer, improved. It is not that expensive either.
Most combo products with ALA and carnitine have much lower milligrams of both.
Look up iherb.com for savings.
