L-Carnosine Supports Cellular Rejuvenation*


•Jarrow FORMULAS® provides the highest quality L-Carnosine available

What does L-Carnosine do?

L-Carnosine is a dipeptide that is found in the brain, heart, skin, muscles, kidneys and stomach. L-Carnosine supports healthy aging and cellular rejuvenation by its effects on two mechanisms: Glycation and Free Radical Damage.* Glycation is the uncontrolled crosslinking of sugar molecules to proteins and is implicated in loss of cell function, genome integrity and accelerated aging. L-Carnosine also supports brain function by reducing lipid peroxidation and stabilizing cell membranes during the aging process.*

Here are some of the many uses of L-Carnosine:


Research shows that L-Carnosine is one of the most profound antioxidants ever studied. It has been proven to significantly reduce oxidative stress, and inhibit the intracellular formation of reactive oxygen species and reactive nitrogen species.Moreover, L-Carnosine has been found to regenerate cells approaching senescence (the end of the life cycle of dividing cells), making L-Carnosine a remarkably potent, biologically active, and clinically important antioxidant.

Sports Nutrition/Medicine

Human muscle cells (myocytes) naturally have very high concentration levels of L-Carnosine. Specifically, L-Carnosine is preferentially located and utilized in type II muscle fibers, especially the type II muscle twitch fibers which are most closely associated with athletic performance. Reasearch has shown the L-Carnosine acts as a buffer in muscle, keeping pH levels from failing during periods of peak performance, thus preventing fatigue and allowing for sustained performance.

Nitric Oxide Substrate

The natural substate for generating nitric oxide synthase (NOS) activity has been shown in published research to be L-Carnosine, producing a multi-fold increase in activity versus all other compounds tested. Because of L-Carnosine’s NOS properties, studies show that it has meaningful applications in cardiovascular health and function. Specifically, L-Carnosine has been shown to have anti-inflammatory, vasodilation, and inotropic (increased cardiac output) properties.


Because of L-Carnosine’s well defined role in protecting and extending the life span of human DNA, cells lipids and proteins, research shows that it can and should play a fundamental role in meaningful anti-aging protocols. Studies demonstrate that L-Carnosine can markedly impact not only the many clinical markers of the aging process, but also the physical signs of aging-such as, the visual appearance of skin, by inhibiting the cross-linking of collagen.

Neurological Function

L-Carnosine is found in especially high levels in the brain, and in particular is concentrated in nerve cells (neurons). Studies demonstrate that L-Carnosine enhances frontal lobe function and is neuroprotective. Clinical testing has shown that the brain uses L-Carnosine to protect against cross-linking, glycation, excitotoxicity, and oxidation. Because of its role in neurological function, research shows the L-Carnosine may be of significant benefit in autism, alzheimer’s, and epilepsy.


L-Carnosine is well established in scientific literature as the most potent, naturally-occurring inhibitor of AGEs (Advanced Gycation Endproducts, which are characterized as the cross-linking of proteins with glucose that lead to oxidized end-products). The occurrence and buildup of AGEs have been closely associated with the development of complications common with type II diabetes (mellitus)-including, cataracts, neuropathy, cardiovascular disorders, and kidney failure.
