Mechanism

CoQ10 functions as an essential electron carrier in the mitochondrial electron transport chain (Complex I to III and Complex II to III), directly supporting oxidative phosphorylation and ATP synthesis. In its reduced form (ubiquinol), it serves as a potent lipid-soluble antioxidant, protecting mitochondrial membranes and LDL particles from peroxidation. It also modulates the mitochondrial permeability transition pore (mPTP) and supports endothelial NO synthase coupling.

Standard Dosing

100-200mg ubiquinol daily

Timing

With meals containing fat. Morning or midday preferred (may be mildly energizing).

Cycle Duration

ongoing

Side Effects

  • Mild GI upset
  • Insomnia (if taken late)
  • Rare: skin rash

Contraindications

  • Caution with warfarin therapy (requires INR monitoring)

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
