Mechanism

ALA is a dithiol compound that functions as a cofactor for mitochondrial alpha-keto acid dehydrogenases (pyruvate dehydrogenase, alpha-ketoglutarate dehydrogenase). Both ALA and its reduced form DHLA are potent antioxidants capable of regenerating other antioxidants including vitamin C, vitamin E, and glutathione. ALA activates AMPK, improving glucose uptake via GLUT4 translocation, and modulates NF-kB-mediated inflammatory signaling. It chelates redox-active metals (Fe2+, Cu2+).

Standard Dosing

300-600mg R-ALA daily

Timing

On empty stomach, 30-60 min before meals. Split doses for higher amounts.

ongoing or cycle 12 weeks on, 4 weeks off

Side Effects

  • GI upset/nausea
  • Skin rash
  • Hypoglycemia symptoms
  • Body odor changes

Contraindications

  • Thiamine (B1) deficiency (ALA increases thiamine demand)
