Carnosine

Key Benefits#

• Potent anti-glycation (prevents protein cross-linking/aging)
• Broad-spectrum antioxidant in muscle and brain
• Extends cell lifespan and protects telomeres
• Improves muscle performance and delays fatigue (pH buffering)
• Neuroprotective against Alzheimer's amyloid-beta
• Wound healing acceleration
• Anti-cataract properties (eye health)
• Improves diabetes complications via AGE prevention
• Chelates excess copper and zinc

Mechanism of Action#

Carnosine acts through multiple complementary anti-aging mechanisms: (1) Anti-glycation: Reacts with reactive carbonyl species and advanced glycation end products (AGEs), preventing protein cross-linking that contributes to tissue stiffening and aging. (2) Antioxidant: Scavenges reactive oxygen species (ROS), particularly hydroxyl and peroxyl radicals, protecting proteins, lipids, and DNA. (3) pH buffering: In muscle, carnosine acts as a pH buffer during high-intensity exercise, delaying acidosis and fatigue. (4) Metal chelation: Chelates copper, zinc, and iron, reducing pro-oxidant metal-catalyzed reactions. (5) Telomere protection: In cell culture studies, carnosine extends the lifespan of human fibroblasts and rejuvenates senescent cells.

Dosing Protocols#

Side Effects#

Contraindications#

No known contraindications. Safe for long-term use. Avoid with known dipeptide sensitivity.
