The causes of ageing are usually regarded as multifactorial; thus effective regulation might be achieved by intervention at multiple sites. It has been suggested that the endogenous dipeptide carnosine, also available as a food supplement, possesses anti-ageing activity and may achieve its reported age-alleviating effects via a number of mechanisms. Carnosine's possible anti-ageing mechanisms are therefore discussed; the evidence suggests that inhibition of the mechanistic target of rapamycin and carbonyl scavenging may be involved.
