R Alpha Lipoic Acid
R-alpha lipoic acid (R-ALA) is the naturally occurring, more bioactive form of alpha-lipoic acid with antioxidant and mitochondrial roles. Evidence supports use for diabetic neuropathy and possible modest effects on insulin sensitivity; claims about stroke prevention or routine metal detox are not proven. Typical supplemental doses range 100-600 mg/day; consult a clinician if you have diabetes or take medications.
