Nutrient blend improves function of aging brain: rat study - Nutra USA,
7/21/10 - "NT-020 is a combination of blueberry, green
tea extract, carnosine and vitamin D3 ... The NT-020 group demonstrated
increased adult neural stem cell proliferation in the two main stem cell niches
in the brains and improvement in learning and memory"
Natural substance NT-020 aids aging brains in rats, study finds -
Science Daily, 7/20/10 - "Aging has been linked to
oxidative stress, and we have previously shown that natural compounds made
from blueberries, green tea, and amino acids, such as carnosine, are high in
antioxidants and have anti-inflammatory and anti-oxidative activity .... The
combination of these nutrients, called NT-020, creates a synergistic effect
that promotes the proliferation of stem cells in the aged animals ... NT-020
may have not only a positive effect on the stem cell niche ... NT-020 may
have far-reaching effects on organ function beyond the replacement of
injured cells, as demonstrated by cognitive improvement in the NT-020 group"
Evidence That Popular Dietary Supplement May Help Prevent, Treat Cataracts
- Science Daily, 7/15/09 - "The scientists exposed
tissue cultures of healthy rat lenses to either guanidine — a substance
known to form cataracts — or a combination of guanidine and carnosine. The
guanidine lenses became completely cloudy, while the guanidine/carnosine
lenses developed 50 to 60 percent less cloudiness. Carnosine also restored
most of the clarity to clouded lenses. The results demonstrate the potential
of using carnosine for preventing and treating cataracts, the scientists

neuroprotective in focal cerebral ischemia and appears to influence
deleterious pathological processes that are activated after the onset of
How Carnosine Protects Against Age-Related Disease
- Life Extension Magazine, 1/06 - "By
preventing the formation of dangerous AGEs, carnosine may help the body’s
proteins retain their youthful vigor and function. Moreover, studies demonstrate
that carnosine is also a powerful antioxidant. Carnosine’s age-defying effects
make this critical nutrient an essential cornerstone of every anti-aging
of Aging - Life Extension Magazine, 1/04 - "Carnosine and several antioxidants were tested for their ability to protect cells exposed to 90% oxygen from chromosomal damage. Only carnosine exerted
significant protection, reducing the level of chromosomal damage by two-thirds"
Food Cooked At High Temperature Accelerates Aging - Life Extension Magazine, 5/03 -
"consuming foods high in glycotoxins might be responsible for the induction of a low-grade, but chronic state of inflammation. In
addition, the glycotoxins in food cooked at high temperatures also promote the formation of glycotoxins in our living tissues. The implication of these findings is profound ... Inflammatory cytokine production can be suppressed with the proper supplementation of fish oil, DHEA, vitamin K and nettle leaf extract ...
It is also important to avoid over consumption of foods high in arachidonic acid (beef, egg yolk, dairy, etc.) ... Consuming at least 1000 mg a day of carnosine, and/or 300 mg of the European drug aminoguanidine
can inhibit pathological glycation reactions in the body"
Clear Vision - Life Extension Magazine, 2/03 - "It is likely that glycation plays a role in aging in non-diabetics as well, especially those who eat diets high in sugars and refined carbohydrates or those who have blood
sugars higher than normal but not high enough to merit a diabetes diagnosis ... Carnosine's best-known effect, however, is its ability to prevent the formation of advanced glycated end products (protein crosslinks). Carnosine competes with proteins for the binding sites they would occupy on sugar molecules, making it the best glycation preventative currently recognized in the world of nutrition research"
Anti-Aging Effects of Carnosine - Life Extension Magazine, 1/03 -
"Carnosine quenches the most destructive protein-oxidizing agent (the hydroxyl radical). One study showed carnosine was the only antioxidant to significantly protect cellular
chromosomes from oxidative damage.2 Antioxidants cannot completely protect proteins. Nature's second line of defense is to repair or remove damaged proteins.3 This is where carnosine demonstrates its most profound anti-aging effect ... Studies show that carnosine is effective against cross-linking and the formation
of advanced glycation end products (AGE).6,7 Glycated proteins produce 50-fold more free radicals than nonglycated proteins and carnosine may be the most effective anti-glycating agent known"
Healthspan: Hormones, Supplements, Diet and Exercise - Life Extension Magazine, 10/02 -
"Besides its anti-glycation activity, carnosine protects against damage by aldehydes. It also chelates metals, buffering against an excess of zinc and copper. Carnosine has also been
shown to inhibit the formation of amyloid plaque characteristic of Alzheimer’s disease"

Nature's pluripotent life extension agent - Life Extension Magazine, 1/01 -
"Carnosine distinctly improved the appearance of the aged mice, whose coat fullness and color remained much closer to that of young animals. Significantly more carnosine-treated mice had
glossy coats (44% vs. 5%), while significantly fewer had skin ulcers (14% vs. 36%) . . . .The sharpest contrast between the treated and untreated mice was seen in their behavior. Only 9% of the untreated mice displayed normal behavioral reactivity, compared to 58% of the carnosine treated mice."
Young Forever, Putting new research findings into practice - Life Extension Foundation, 12/99 -
"The formation of AGE happens in everyone and is a major factor in the aging process itself. These damaged proteins may lead to premature signs of aging (wrinkles and brown
spots) and in the long run to damaging effects on most organ systems within the body . . . The amino acid carnosine is a natural AGE inhibitor found in high concentrations in the brain, muscle tissue and the lens of the human eye. It is also known to be an antioxidant capable of protecting cell membranes and other
cell structures. In vitro studies demonstrated that carnosine inhibits glycosylation and crosslinking of proteins induced by reactive aldehydes, and that it is effective in reducing AGE formation by competing with proteins for binding with the sugars. The authors suggest that this nontoxic compound should be
explored in the treatment of such conditions as diabetic complications, inflammatory disorders, alcoholic liver disease and possibly Alzheimer's disease."

"The result is the formation of AGEs (Advance Glycosylation End-products). These are abnormal, cross-linked. oxidized products
which are thought to cause extensive damage to the organism. Carnosine blocks this deleterious reaction. protecting against cross-linking of proteins, cross-linking of proteins to DNA molecules, and formation of other abnormal proteins, all of which are fundamental features of the aging process . . . carnosine
reacts with and inactivates aldehydes and ketones. reducing protein glycosylation and the formation of AGEs. It also binds to already formed AGEs and inactivates them . . . treatment with carnosine was found to reduce or completely prevent cell damage caused by beta amyloid, the substance found in the brain of
Alzheimer's disease patients . . . 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. This is not surprising 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"

inhibits KRAS-mediated HCT116 proliferation by affecting ATP and ROS production
- Cancer Lett. 2011 Aug 5 - "Carnosine is a natural
dipeptide that has generated particular interest for its antioxidant, anti-aging
and especially for its antiproliferative properties. In this study, we
demonstrate that carnosine inhibits the proliferation of human HCT116 colon
cancer cells ... Our findings support the concept that carnosine could inhibit
HCT116 cell growth via its antioxidant activity and its ability to affect
Antioxidative and Anti-Inflammatory Protection from Carnosine in the Striatum of
MPTP-Treated Mice - J Agric Food Chem. 2010 Oct 6 - "The preintake of
carnosine significantly attenuated MPTP-induced glutathione loss, retained the
activity of GPX and SOD, diminished oxidative stress, and lowered inflammatory
cytokines and nitrite levels as well as suppressed iNOS activity (P < 0.05).
MPTP treatment significantly suppressed GPX mRNA expression and enhanced iNOS
mRNA expression (P < 0.05). Carnosine preintake significantly elevated GPX mRNA
expression and declined iNOS mRNA expression (P < 0.05). Preintake of carnosine
also significantly improved MPTP-induced dopamine depletion and maintained
3,4-dihydroxyphenylacetic acid and homovanillic acid levels (P < 0.05). These
results suggest that carnosine could provide antioxidative and anti-inflammatory
protection for the striatum against the development of Parkinson's disease"
