Curcumin (with Piperine/Liposomal) vs Glycine + NAC (GlyNAC)

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

Mechanism

Combination that restores glutathione synthesis. Age-related glutathione deficiency is driven by glycine and cysteine precursor depletion, not enzyme dysfunction. GlyNAC corrects oxidative stress, mitochondrial dysfunction, inflammation, and insulin resistance in older adults.

Contraindications

• Active stomach ulcer (NAC)
• Asthma (NAC may cause bronchospasm in rare cases)
