AREDS2 supplements vs peptide antioxidants
AREDS2 mechanism: Vitamins C, E, zinc, copper, lutein, zeaxanthin provide direct antioxidant effects. Vitamin C and E scavenge free radicals. Lutein and zeaxanthin absorb blue light and provide local macular antioxidant activity. Zinc cofactor for retinal enzy

- AREDS2 mechanism: Vitamins C, E, zinc, copper, lutein, zeaxanthin provide direct antioxidant effects. Vitamin C and E scavenge free radicals. Lutein and zeaxanthin absorb blue light and provide local macular antioxidant activity. Zinc cofactor for retinal enzymes. Nutrients supporting existing cellular functions.
- GHK-Cu antioxidant approach: Upregulates endogenous antioxidant enzymes (SOD, catalase, glutathione peroxidase) rather than providing antioxidants directly. Teaches cells defending themselves versus supplying external antioxidants. Potentially more sustainable approach as enzyme upregulation persists beyond peptide presence. Also broader effects on gene expression beyond just antioxidants.
- Synergistic potential: AREDS2 vitamins provide immediate antioxidant protection while GHK-Cu builds long-term antioxidant capacity. Combination likely superior to either alone addressing both immediate oxidative stress and enhancing cellular defenses. AREDS2 well-proven and affordable making it foundation with peptides potentially providing additional benefits.
