Catalog Description

L-carnosine is a naturally occurring dipeptide of beta-alanine and histidine, concentrated in skeletal muscle and brain tissue. It buffers intramuscular pH during high-intensity exercise and has documented antioxidant and anti-glycation (advanced glycation end-product-reducing) properties, reviewed alongside taurine, creatine, and anserine in human nutrition literature.

Catalog descriptions reflect research context only. Not a medical claim or treatment recommendation.

Research Profile

Half-Life

Rapidly hydrolyzed by serum carnosinase; oral supplementation raises muscle carnosine via beta-alanine pathway more efficiently

Onset

Muscle carnosine loading studied over weeks

Administration Routes (Research)

Oral

Reported Research Effects

Intramuscular pH buffering during high-intensity exercise
Antioxidant and anti-glycation properties

Reported Research Side Effects

Human safety, pharmacokinetics, and interaction data are incomplete

Data source: Primary literature, regulator records, trial registries, and identity-specific evidence search

Reflects preclinical/research literature context only. Not a medical claim, dosing instruction, or treatment recommendation.

Research Protocols Reported in the Literature

2 g/day [Oral; 14 weeks; Daily]Source: randomized prediabetes/type 2 diabetes cognition study

Research Notes

Human trials are small and heterogeneous; a 2026 review rated the evidence base low-strength. The prior 500-2000 mg generic anti-aging range was not a single validated protocol.
