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.

Cycle Duration

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)
  • Hypoglycemia-prone individuals without monitoring
  • Autoimmune thyroid conditions (monitor thyroid function)

Resveratrol

Supplements

Mechanism

Resveratrol activates SIRT1 (the longevity sirtuin) via allosteric binding, promoting deacetylation of PGC-1alpha (mitochondrial biogenesis), FOXO3 (stress resistance), and p53 (DNA repair). It inhibits NF-kB and COX-2, reducing chronic inflammation. Resveratrol also activates AMPK independently of SIRT1 and inhibits phosphodiesterases (PDEs), raising cAMP levels. It improves endothelial function via eNOS upregulation and NO production.

Standard Dosing

250-500mg trans-resveratrol daily

Timing

Morning with a fat-containing meal. Often taken alongside NMN for synergistic sirtuin activation.

Cycle Duration

ongoing

Side Effects

  • GI upset/diarrhea at high doses
  • Headache
  • Joint pain (rare)
  • Insomnia (if taken late)

Contraindications

  • Estrogen-sensitive cancers (theoretical ER agonism)
  • Bleeding disorders
  • Pregnancy/lactation
