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)

Mechanism

Curcumin modulates over 100 molecular targets. Primary mechanisms include direct inhibition of NF-kB nuclear translocation (master inflammatory transcription factor), suppression of COX-2 and iNOS expression, inhibition of STAT3 and AP-1 signaling, and activation of Nrf2-ARE pathway upregulating Phase II detoxification enzymes (glutathione S-transferase, heme oxygenase-1). It also inhibits mTOR signaling and modulates epigenetic enzymes (HATs, HDACs, DNMTs).

Standard Dosing

500-1000mg curcuminoids daily (enhanced bioavailability form)

Timing

With meals containing fat. Piperine enhances absorption 2000% but also affects drug metabolism.

Cycle Duration

ongoing

Side Effects

  • GI upset/diarrhea at high doses
  • Yellow staining of teeth/skin
  • Rare: contact dermatitis
  • Potential iron depletion with chronic high-dose use

Contraindications

  • Gallbladder obstruction/gallstones (stimulates bile flow)
  • Iron-deficiency anemia (chelates iron)
  • Scheduled surgery (discontinue 2 weeks prior)
  • Pregnancy at therapeutic doses
