Carnosine
Multi-UseAlso known as: L-Carnosine, Beta-Alanyl-L-Histidine
Emerging ResearchWhat is Carnosine?
An antioxidant dipeptide found naturally in muscle and brain tissue. Studied for its anti-glycation properties that protect proteins from sugar-related damage linked to aging.
How it works
Acts simultaneously as an antioxidant, metal chelator, and anti-glycation agent. Protects proteins and cell membranes from oxidative damage and inhibits cross-linking of proteins caused by excess glucose (glycation).

Frequently asked questions
What is glycation and why does it matter for skin?
Glycation is a process where excess sugar molecules bond to proteins like collagen, creating stiff cross-linked structures called AGEs (advanced glycation end products). This makes collagen brittle and contributes to wrinkles, sagging, and a dull complexion. Carnosine acts as an anti-glycation agent that may help prevent this process.
Should I take carnosine orally or use it topically?
The enzyme carnosinase rapidly breaks down carnosine in the bloodstream, limiting oral bioavailability. Topical delivery is being studied but evidence is early. Some people take oral carnosine regardless, but the real-world anti-aging benefit in humans remains unproven for either route.
