- Its 400 mg of alpha-lipoic acid (filed by NIH under alpha lipoic acid) is higher than 93% of the 2,407 alpha lipoic acid products that print an amount; 137 list more.
The NIH database records one serving a day from the label's directions; its % Daily Values are for adults and children 4 or more years of age. The directions as printed are further down this page.
