What is L-Carnosine?
L-Carnosine (beta-alanyl-L-histidine) is a dipeptide composed of beta-alanine and L-histidine, found in high concentrations in the brain, skeletal muscle, heart, and other metabolically active tissues.

Community and editorial ratings, out of 5:
How to take it
- Standard dosage: 500-1,000 mg per day for general neuroprotection and anti-ageing
- Clinical dosage: Up to 2,000 mg per day has been used in clinical trials for cognitive support
- Carnosinase consideration: The enzyme carnosinase breaks down carnosine in human blood. Higher doses or divided doses (twice daily) help maintain...
- Timing: Take with food to minimise potential GI discomfort. Divide into 2 doses (morning and evening) for sustained levels
- Onset: Antioxidant effects are immediate. Anti-glycation and neuroprotective benefits accumulate over weeks to months
Watch out for
- Excellent safety profile: L-Carnosine is a natural dipeptide found abundantly in meat and is well tolerated at supplemental doses up to 2 g/day
- Histamine consideration: Contains histidine, which can be converted to histamine. Individuals with histamine intolerance should start with lower doses and...
- Vegetarians and vegans: Carnosine is found exclusively in animal tissues. Vegetarians and vegans have significantly lower tissue carnosine levels and may...
- Drug interactions: No significant drug interactions known at standard supplement doses
- Pregnancy: Dietary carnosine from meat is safe. Supplement-dose safety during pregnancy has not been specifically studied
The science, if you're curious.
- Acts as a sacrificial peptide that reacts with reactive carbonyl species (methylglyoxal, malondialdehyde), preventing them from forming AGEs on critical...
- Chelates excess zinc, copper, and iron ions that catalyse oxidative damage and promote amyloid-beta aggregation in the brain
- Directly scavenges reactive oxygen species including hydroxyl radicals and superoxide, and protects cell membranes from lipid peroxidation
- Acts as an intracellular pH buffer, preventing acidosis during periods of high metabolic activity or ischaemia
Where to find it
- Capsules: Widely available from supplement retailers in 500 mg and 1,000 mg capsules
- Powder: Available as bulk powder for flexible dosing
- Food sources: Red meat, poultry, and fish are the primary dietary sources. Beef and turkey breast are particularly rich
- Beta-alanine alternative: Beta-alanine supplementation (the rate-limiting precursor) also raises muscle and brain carnosine levels over time
