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

Best Stacking Partners

Omega-3QuercetinBoswelliaGingerBlack pepper (piperine)

Mechanism

Odd-chain saturated fatty acid identified as essential. Strengthens cell membranes by integrating into phospholipid bilayer, activates AMPK and PPAR-alpha/delta, and inhibits mTOR. Repairs mitochondrial function. Epidemiologically associated with reduced cardiometabolic disease.

Contraindications

  • None established
