Brain Nutrient Fights Alzheimer's

New research shows that a powerful natural compound could be used to prevent – or even treat – Alzheimer’s disease.

This beneficial nutrient is called carnosine. It is an amino acid that is naturally found in high concentrations in muscle tissue and in the brain. But studies show that these levels are depleted in patients with Alzheimer’s.

The new study shows benefits against Alzheimer’s. It was conducted by Dr. Stefano Sensi. He’s a neurologist at the University of California, Irvine (UCI). The National Institutes of Health has recognized him for his work.

He says that carnosine has “neuro-protective activity.” And it can protect the brain in three ways.

Shielding the Brain in Three Ways

Scientists are still studying how Alzheimer’s develops. But they know it has something to do with the formation of abnormal clumps (amyloid plaques) and tangled fibers (neurofibrillary tangles) within the brain. It’s also associated with the failure of mitochondria in the brain.

Carnosine is a powerful antioxidant, with particular benefits on nerve endings. It is also a chelating agent. So it can bind to heavy metals and remove them from your body. And research shows that it can have an impact on all three conditions related to Alzheimer’s.

Dr. Sensi tried carnosine on mice with spatial memory decline. This is the part of memory responsible for recording information about your environment.

One group of mice was treated with carnosine. Another group was used as a control. The mice were trained for three days and then given a maze test.

During the training, all of the mice learned at the same rate. But when the researchers tested spatial memory skills, the untreated mice showed short-term memory loss. The mice treated with carnosine did not.

Then the researchers examined the brains of the treated mice. They found a significant decrease in amyloid beta protein, which causes plaques to form. They also saw improvement in mitochondrial function.

Carnosine didn’t completely reverse cognitive decline. But it did begin a trend toward better brain function.

The Case for Eating Meat

Carnosine is critical for the proper functioning of your brain and nervous system. And the most abundant natural source of this vital nutrient is meat. Beef contains about 1,500 mg of carnosine per pound, while pork and poultry contain about 2,000 mg per pound.

If you eat meat several times a week, you should be getting plenty of carnosine in your diet. Always choose grass-fed beef or pastured pork and poultry whenever possible.

However, if you’re a vegetarian, you’re likely not getting any carnosine in your diet. In this case, you should consider taking a carnosine supplement.

Dr. Marios Kyriazis is the medical advisor to the British Longevity Society. He notes that carnosine is safe and well tolerated in doses up to 800 mg per day and higher.

Increasing your carnosine intake is good for your brain and your muscles. It’s one of the best anti-aging compounds you can get in your diet.

To your best health,

    So how much better is grass fed beef vs CAFO garbage? I know the EFAs are incredibly better as is virtually every aspect of them.
    Another question, how about healthy (non rBST at the least, but organic dairy in regards to this amino acid?

    These are pretty much questions, not comments. Boy, i really make bad comments!

    I recently read a article regarding a female MD whose husband had alzheimer’s disease. He noted dramatic improvement after consuming coconut oil. Have you heard of this?

    Michael Jelinek,

    Dear Sir :
    May I begin by introducing myself please. I have been a practicing neurosurgeon for 30 years, both in the academics and private sector. During this time I have written and presented over 150 papers, abstracts, and chapters in books. My Phd is in Neuroscience, and I also have bachelors degrees in Biochemistry and Physiological Psychology. I have retired because of failing vision from glaucoma, the underlying reason for discovering your web site, in a search for better preventative medications to stabilize the retina and arrest further apoptosis of retinal ganglion cells (RGC’s). I have become a member of your Health watch.

    Overall the scientific quality of your writing and daily newsletters are excellent, but as a company w/ share holders, I expect to have intercalated into the discussions of health products your sales pitch. It goes w/ the territory. As a rule I would say that your “hype/miracle cure” index (HMCI index) is low density.

    However, recently I received two communications, the one yesterday, quite offensive, as it began w/ thanking me for purchasing the PT Elixir , which I had not done ! And sadly, today’s NHD email again pummels my sensitivity w/ more sensationalism, including a personal testimony about the product. Gee wiz, I worked 120 hours a week as a resident at Johns Hopkins, and 80 hours a week my entire life practicing neurosurgery without taking any stimulants and managed just fine w/out your Elixir ! For me, this type of writing seriously detracts from the validity and credibility of your dossier !

    I do a great deal of internet research, and writing, and critically analyze detailed scientific basic science and clinical papers. I have been the PI on grants and ran regional clinical trials on brain tumors in central New York. While many Health/Supplement web sites spew forth vitriol about how the Western Medicine Establishment and Pharmaceutical Companies are suppressing ” simple miracle cures ” for money, and perpetuating chemotherapy and “statin” scams, they themselves prey on desperate individuals seeking cures for their ailments. I’d estimate that better than 50% of what you read is hyperbole, and the industry has no regulation. Thus supplement companies and Health blogs/Newsletters can not only say anything they chose, but companies sell products which are not absorbed by the human alimentary tract, sold in sub-therapeutic doses, but also use cheap biologically inactive isomers and substitute deleterious plant sources. The whole flax seed story, it is good furniture oil, is perhaps the most glaring and a blatant example ( talk about a money hog; the Budwig Institute from Germany), as is the isomeric problems w/ resveratrol and alpha lipoic acid, and absorption of curcumin, which has been shown to prevent apoptosis in RGC’s.

    With that being said, I would respectfully request that you continue to closely monitor National Health Dosisier’s HMC index so you don’t scare off educated consumers.

    Finally, I do have a lot of free time, and would be interested in pursuing further communications with you, and if mutually amenable, even consider doing some research, writing, and joining your organization.
