L-Carnosine is a natural dipeptide composed of beta-alanine and L-histidine, widely distributed in animal muscle and brain tissues. It features strong antioxidant, anti-glycation, metal chelation and pH-buffering effects, with broad applications across cosmetics, nutraceuticals, feed and food industries.
L-Carnosine scavenges free radicals, chelates heavy metal ions such as copper and zinc, inhibits lipid oxidation and reduces cellular oxidative damage.
Blocks the formation of advanced glycation end products (AGEs), prevents collagen cross-linking that causes dull yellow skin, sagging and fine lines. It is a mainstream anti-glycation ingredient in skincare products.
Neutralizes lactic acid produced during exercise to relieve muscle soreness and delay fatigue, serving as a core raw material for sports nutrition.

L-Carnosine is a natural dipeptide consisting of beta-alanine and L-histidine. It is widely distributed inside animal muscle and brain tissues.
In cosmetics, L-Carnosine is a key anti-aging, anti-glycation, and brightening agent. It prevents collagen cross-linking, reducing skin dullness, sagging, and fine lines.
It serves as an effective cellular pH buffer that neutralizes lactic acid built up during exercise, helping to relieve muscle fatigue and support recovery.
We offer 1kg packages (composed of double plastic and Aluminum foil bags inside, with an outer box) and bulk options of 10kg or 25kg and above (delivered in drums or cartons).
For orders below 25kg, express methods (EMS, DHL, UPS, FedEx) deliver door-to-door within 3-7 days. Larger volumes can be shipped via air freight (3-7 days to airport) or sea freight (10-35 days to port).
The product is a high-grade white powder tested under HPLC protocols to guarantee specification compliance and strict heavy metal and microbiological safety controls.
