Carnosine- Summary
- Liraglutide is a long-acting GLP-1 receptor agonist approved for type 2 diabetes (Victoza) and chronic weight management (Saxenda). It reduces appetite, slows gastric emptying, improves insulin secretion, and promotes weight loss of 5–10% in clinical trials.
- 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
- ~13 hours (once-daily dosing)
- ~1.5 minutes (rapidly hydrolyzed to beta-alanine and histidine by carnosinase in blood; tissue levels maintained via constant synthesis)
