Summary

Carnosine (β‑alanine‑L‑histidine) is a naturally occurring dipeptide found in skeletal muscle, brain, and cardiac tissue. It is used as a dietary supplement for its antioxidant and buffering properties and is investigated for anti‑aging, neuroprotective, and metabolic benefits.

Mechanism of Action

Acts as an intracellular pH buffer, antioxidant, metal‑chelator and anti‑glycation agent; modulates calcium handling in muscle and brain tissue.
