L-carnosine (β-alanyl-L-histidine) is a naturally occurring dipeptide—composed of β-alanine and L-histidine—used globally as a high-value ingredient in dietary supplements, cosmetics, functional foods, and pharmaceuticals. Abundant in human muscle and brain tissue, its antioxidant, anti-glycation, and cell-protective properties make it a top choice for B2B manufacturers targeting anti-aging, sports nutrition, and health-focused products. As one leading L-carnosine bulk supplier, we provide purity grades from 98% (food grade) to 99.5% (pharmaceutical grade).

 L-Carnosine Benefits
L-Carnosine BenefitsAdvanced Glycation End Products (AGEs) cause skin wrinkling and elasticity loss. L-carnosine blocks AGE formation by competing with collagen for sugar molecules. A 2024 study in Journal of Cosmetic Science found 1% L-carnosine in serums reduced skin AGEs by 22% in 12 week
L-carnosine buffers lactic acid and boosts ATP production, improving athletic endurance. A double-blind trial with pro athletes showed 2g/day of L-carnosine increased time-to-exhaustion by 15% and reduced muscle soreness by 30%. This makes it one core ingredient for sports nutrition supplements formulations.
L-carnosine neutralizes reactive oxygen species (ROS) and reactive nitrogen species (RNS), two free radicals linked to inflammation and chronic diseases. Unlike single-target antioxidants (e.g., vitamin C), it also chelates heavy metals (e.g., copper, iron) that trigger oxidative stress. Besides, L-carnosine protected skin fibroblasts from UV-induced damage, supporting its use in suncare and post-sun repair products.
L-carnosine regulates glucose metabolism by improving insulin sensitivity and reducing insulin resistance. A 2024 study in Nutrients reported that overweight adults who took 2g/day of L-carnosine for 12 weeks saw a 18% decrease in HOMA-IR (insulin resistance index). Additionally, it protects cardiovascular cells from oxidative damage: animal studies show L-carnosine reduces arterial plaque formation by 25%, making it a valuable ingredient for heart health supplements.
L-carnosine's versatility makes it a top choice for products like anti-aging serums/creams, and suncare products in cosmetics industry; sports nutritional supplements formulations, anti-aging supplements formulations, and functional food & beverages blends targeting health-conscious consumers.
