L-Carnosine is a dipeptide concentrated in skeletal muscle, heart, and brain tissue. It was discovered in 1900 and has been the subject of extensive longevity research. Its unique ability to protect proteins from glycation damage — a key driver of aging — has made it one of the most studied anti-aging compounds in the dipeptide class.
Dosage Information (Research Use)
Oral: 500-2000mg daily in divided doses. Some researchers use higher doses (up to 3g/day). Available as a dietary supplement.
Reconstitution & Handling
Oral supplement — no reconstitution needed. For research solutions, dissolve in water.
Half-Life & Pharmacokinetics
~20 minutes plasma; tissue-dependent
Reported Observations in Literature
Very well tolerated orally. Occasional mild GI discomfort. No significant adverse effects reported at standard supplemental doses. May affect histamine levels due to histidine component.
