Carnosine- Summary
- Cagrilintide is a long-acting amylin analog developed by Novo Nordisk. Amylin is a peptide hormone co-secreted with insulin from pancreatic beta cells. Cagrilintide slows gastric emptying, suppresses glucagon, and reduces appetite via central amylin receptors. In combination with semaglutide (CagriSema), Phase 2 trials achieved approximately 15% body weight reduction. Phase 3 trials (REDEFINE program) are ongoing.
- Carnosine is an endogenous dipeptide (beta-alanine + histidine) found in high concentrations in muscle and brain. It is a potent anti-aging molecule with broad spectrum antioxidant, anti-glycation, anti-carbonylation, and metal chelating properties, making it one of the most protective naturally occurring dipeptides.
- Half-Life
- ~7–10 days
- ~1.5 minutes (rapidly hydrolyzed to beta-alanine and histidine by carnosinase in blood; tissue levels maintained via constant synthesis)

- Typical Dose
- 0.16 mg → 0.3 mg → 0.6 mg → 1.2 mg → 2.4 mg
- 1,000–2,000 mg
- Frequency
- Once weekly
- Once to twice daily with meals
- Key Benefits
- ~15% body weight reduction in combination with semaglutide (CagriSema Phase 2)
- Synergistic appetite suppression complementing GLP-1 receptor agonists
- Reduces post-meal glucagon excursions improving glycemic control
- Slows gastric emptying contributing to prolonged satiety
- Once-weekly dosing via subcutaneous injection
- Potential for greater weight loss than semaglutide monotherapy
- 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
