Carnosine: The Amazing Anti-Aging Nutrient

How does carnosine work as an anti-aging nutrient?

Proteins are the substances most responsible for the daily functioning of living organisms. When proteins are damaged and modified—due to a variety of complex chemical processes including carbonylation,17 glycosylation,18 lipid peroxidation,19 cross linking,20 and the production of AGEs (advanced glycosylation end-products)2122 —there is a dramatic impact on the functioning and appearance of the body. Our faces begin to sag and wither, our energy levels decrease, and without our even realizing it, all of a sudden we look differently than we did 20 or 50 years ago.

According to Karin Granstrom Jordan, M.D. ("Carnosine: Nature's pluripotent life extension agent" Life Extension Magazine, Jan, 2001), "Modified proteins accumulate as we age, while carnosine levels are declining. Once a protein is modified it has lost its ability to function normally, and when a significant portion of the body's protein has reached this point, the body becomes more prone to degenerative diseases." Carnosine is now believed to bind and modify damaged proteins in a vital process that helps our cells properly target them for removal and replacement.

Experience improved facial appearance, muscular stamina and general well being

In a preliminary anti-aging experiment, Marios Kyriazis MD gave carnosine supplements (50 mg. daily) to 20 healthy human volunteers, aged 40 - 75 years, for a period of 1-4 months. No side effects were reported. Five users noticed significant improvements in their facial appearance (firmer facial muscles), muscular stamina and general well being. Five others reported possible benefits, for example better sleep patterns, improved clarity of thought and increased libido. The rest did not report any noticeable effects.

Although this study evokes optimism, we should note that it was only a preliminary study, was not placebo controlled and relied on the participant's subjective reports.

Dr. Kyriazis reported that it is not surprising that some of the volunteers did not report any noticeable effects because "supplementation with carnosine is not expected to show any significant noticeable benefits in a short time, but it should be used as an insurance against deleterious effects of the aging process. If any benefits are noted, these should be considered as an added extra bonus. It is worthwhile persevering with the carnosine supplementation long term, even if you do not experience any obvious benefits, as you will still be well protected against aging."

Carnosine slows down aging in animals

In one study done on laboratory animals, carnosine was shown to slow the development of aging in "senescence-accelerated" animals (animals bred for rapid aging) when added to their diet. These effects were seen not only on lifespan, but also on behavioral changes and physical deterioration. Carnosine also had a similar though smaller effect on normal, long-lived animals not chosen for their rapid aging features, making it an interesting supplement for those of us worried about premature aging.24

If you want to try a safe and effective anti-aging supplement, you can't go wrong with carnosine. Carnosine offers potent protection against free radicals and protein modification by itself. For added protection, take it along with vitamin E and/or Co-enzyme Q10.
