Carnosine is a life extension superstar for its versatility and potency. In particular, it combats glycation, free radical damage, replicative senescence, telomere shortening and is a chelator of heavy metals. In addition, it has been found to extend the lifespan in mice by 20%.


Glycation and Oxidation

Carnosine has been known for some time now to be very effective in guarding against glycation, the insidious and devastating process over time by which tissues, particularly those of the nervous system, are irreversibly damaged by their permanent combination with sugar molecules. There are a large number of studies at this point, both in vivo and in vitro, demonstrating its efficacy as an anti-glycating agent on a wide array of different tissues and cell types including those of the nervous system and lens of the eye.1,2 In addition to protecting proteins from glycation, it also protects them from oxidation.3 In particular, it has the ability to neutralize the most destructive of protein-oxidizing free radicals – the hydroxyl radical. It was declared by one study to be the only anti-oxidant capable of protecting DNA from oxidation,4 and is key in the body’s ability to repair and remove proteins already damaged by glycation or oxidation.

...and the nervous system from glycation.

Replicative Senescence and Telomere Shortening

As the body’s cells divide telomeres shorten, and due to the telomere position effect, the new cells are ‘older’ or more dysfunctional on a number of fronts. Eventually they become ‘senescent’ where they radically change shape, stop dividing and wait for death. These cells represent the final stage of degradation due to telomere-mediated cellular aging. We believe telomere shortening is the one true underlying cause of aging in all species, so anything that may slow down this process is invaluable to us. And Carnosine has recently been shown to both slow telomere shortening5 and independently, to delay and even revert6 replicative senescence.7

Can delay and even revert replicative senesence..

Slows telomere shortening.

In Vivo Life Extension

One study tested the effect of carnosine on life span and indicators of aging in senescence-accelerated mice. Carnosine extended the life span of the treated mice by 20% on average although the maximum lifespan was not altered.8

    The reversion of senescent cells to cells of a normal phenotype seems to only last, however, as long as the cells continue to be exposed to Carnosine:

    We have shown that late-passage HFF-1 cells retain a juvenile appearance in medium containing 50 mM carnosine, and revert to a senescent phenotype when carnosine is removed (From G., above ..ibid)

    McFarland GA, Holliday R. We have examined the effects of the naturally occurring dipeptide carnosine (beta-alanyl-L-histidine) on the growth, morphology, and lifespan of cultured human diploid fibroblasts. With human foreskin cells, HFF-1, and fetal lung cells, MRC-5, we have shown that carnosine at high concentrations (20-50 mM) in standard medium retards senescence and rejuvenates senescent cultures. These late-passage cultures preserve a nonsenescent morphology in the presence of carnosine, in comparison to the senescent morphology first described by Hayflick and Moorhead. Transfer of these late-passage cells in medium containing carnosine to unsupplemented normal medium results in the appearance of the senescent phenotype. The serial subculture of cells in the presence of carnosine does not prevent the Hayflick limit to growth, although the lifespan in population doublings as well as chronological age is often increased. This effect is obscured by the normal variability of human fibroblast lifespans, which we have confirmed. Transfer of cells approaching senescence in normal medium to medium supplemented with carnosine rejuvenates the cells but the extension in lifespan is variable. Neither D-carnosine, (beta-alanyl-D-histidine), homocarnosine, anserine, nor beta-alanine had the same effects as carnosine on human fibroblasts. Carnosine is an antioxidant, but it is more likely that it preserves cellular integrity by its effects onprotein metabolism.
