About Carnosine
L-Carnosine is a dipeptide of beta-alanine and L-histidine, found naturally in high concentrations in muscle and brain tissue. It acts as an intracellular buffer, antioxidant, and anti-glycation agent — preventing the cross-linking of proteins by sugars (AGEs). Levels decline with age, which has made it a popular longevity supplement. Distinct from beta-alanine, which the body uses to synthesize carnosine endogenously. Generally well tolerated. No established RDA/UL.
What Carnosine supports
- Potent anti-glycation agent — helps prevent AGE formation linked to aging
- Concentrated in brain tissue, may support cognitive health
- Acts as an intracellular pH buffer in muscle during exercise
- Antioxidant and metal chelator, supports cellular defense
How much Carnosine to take
The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.
Effective
500–1500
mg
Most studies use 500–1000 mg/day for anti-glycation and antioxidant benefits. Higher doses (1500–2000 mg) have been used in cognitive and exercise studies. Often taken in divided doses.
Clinical evidence
Moderate clinical evidence. Several clinical trials on anti-glycation and antioxidant effects, but most studies are small
