Alpha-Lipoic Acid: The Complete Guide

600 mg trials, glucose caveats, and why this is not a master-antioxidant personality

ALA is a mitochondrial cofactor that can recycle vitamins C and E and shows up in diabetic neuropathy and glucose conversations. Longevity evidence in healthy people is thin. This guide covers the 600 mg NOW bottle and the hypoglycemia warning if you already take diabetes drugs.

Alpha-Lipoic Acid: The Complete Guide

What It Is

Moderate Evidence

Lipoic acid works in water and fat. That brochure line is true and overused. The interesting literature is glucose handling and neuropathy, not immortality.

Glucose

Moderate Evidence

ALA can add to diabetes medications. That is a safety issue, not a feature you chase without a clinician. See Bikman and berberine if insulin is the actual project.

Stack Position

Emerging Research

Vitamin C, NAC, and food antioxidants already exist on this site. ALA is optional adjunct, not the foundation stack.
