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

Mechanism

Quercetin is a flavonoid that inhibits mast cell degranulation and histamine release, functions as a potent senolytic (selectively clearing senescent cells) when combined with dasatinib or fisetin, and activates AMPK and SIRT1 pathways. It inhibits PI3K/Akt/mTOR signaling, suppresses NF-kB, and modulates JAK-STAT inflammatory cascades. As a zinc ionophore, it facilitates zinc entry into cells, which may inhibit viral RNA-dependent RNA polymerase.

Standard Dosing

500-1000mg daily

Timing

With meals for absorption. For senolytic effect: 3-day pulse monthly on empty stomach.

Cycle Duration

ongoing for general use; pulsed monthly for senolytic protocols

Side Effects

  • Headache
  • Mild GI upset
  • Tingling extremities at high doses
  • Rare: kidney toxicity at very high doses

Contraindications

  • Pregnancy/lactation at high doses
  • Concurrent cyclosporine therapy
