Copper peptides are small peptide molecules naturally capable of binding copper ions
This association remained strong even when comparing trends in peptide levels during the first year with changes in the fasting C-peptide/glucose ratio between the baseline 6 week and 24 month measurements (FDR=0.07)
How to implement: Dosing: General health : 5-10 grams daily Glutathione optimization : 10-15 grams daily (divided doses) Aging/longevity : 15 grams daily (research shows benefits for lifespan) Forms: Glycine powder : Tasteless, mixes in water/coffee/smoothies Collagen peptides : 10-20 grams daily (33% glycine by weight = ~3-7g glycine) Bone broth : Rich source (8-10g glycine per cup) Timing: With meals (supports protein synthesis) Before bed : 3-5 grams (improves sleep quality via NMDA receptor modulation) Synergy with NAC: Combine NAC (600 mg 2 daily) + Glycine (5g 2 daily) for maximum glutathione boost Research shows this combination increases glutathione more than either alone [11] Evidence: A study in older adults found that glycine supplementation (15g daily) increased glutathione by 25% and reduced oxidative stress markers by 30% within 2 weeks [12]
