One of the most powerful antioxidants known, protective for many long-term conditions and one of the most important anti-aging supplements available today (for visibile improvement within months) and sometimes referred to as the “longevity molecule.” 

People are also known to use it to boost stamina and muscle strength.

Prevents disease, brain disorders, and reverses aging.

It’s a heavy-metal scavenger.

helps mitigate the damage caused by sugar intake.

Neuro-repair: L-Carnosine reverses the damage done by advanced glycation end products (AGEs). AGEs are created in your brain by sugars binding to amino acids, and caused by a variety of things including certain food and cooking techniques. Affecting word recall, response time, and cognition.

Brain Energy: L-Carnosine can revive mitochondria and even rescue your brain cells if the mitochondria have stopped functioning.

Neuroprotectant: L-Carnosine has a powerful antioxidant effect on your brain. It continues to lower oxidative damage even after brain cells have been attacked by free radicals, stopping brain cell death and neurodegenerative disorders. Early research suggests that taking L-carnosine by mouth for 8 weeks may improve symptoms in children with autistic spectrum disorders


take with DMAE (NOW-03090) and Acetyl-l-carnitine (ALCAR) to help remove the lipofuscin produced in the body as a negative side effect of carnosine’s protective action.

Other benefits include the prevention and treatment of diabetic complications such as nerve damage, kidney problems and eye disorders like cataracts.

Research suggests that L-carnosine may be helpful for the following health concerns:

1. Chronic Diseases like Diabetes

According to a scientific article published in 2017, “Carnosine, an over-the-counter food supplement, has a promising potential for the prevention and treatment of chronic diseases such as type 2 diabetes, cardiovascular and neurodegenerative diseases through its anti-inflammatory, antiglycation, antioxidative and chelating effects.”

A pilot double-blind, randomized clinical trial published in 2016 evaluated the effects of supplementation on 30 nondiabetic individuals who were either overweight or obese. Half of the subjects took two grams of carnosine daily, and the other half took a placebo for a 12-week period.

The results were positive: Subjects who took carnosine had improved insulin resistance and lower glucose levels compared to placebo takers. Overall, the researchers concluded, “carnosine supplementation may be an effective strategy for prevention of type 2 diabetes.”

2. Alzheimer’s Disease

More clinical studies are still needed, but so far animal and lab studies are pointing toward carnosine’s ability to decrease the buildup of amyloid beta, which is the main component of the plaque found in the brains of Alzheimer patients.

In addition to some animal studies with positive results, a double-blind, randomized controlled clinical trial found that healthy elderly people who took a supplement containing carnosine as well as anserine experienced an improvement in their age-related decline in brain blood flow (which occurs in Alzheimer’s disease) after three months of supplementation. The 39 healthy elderly volunteers (between the ages of 60–78 years old) also saw improvements in memory, specifically verbal episodic memory.

3. Cataracts

Is it possible carnosine eye drops may be able to help cataracts?

A randomized, placebo-controlled study had 26 patients (41 eyes) use topical one percent n-acetylcarnosine (NAC) eyedrops twice daily while the 13 patients (21 eyes) in the control group received placebo eyedrops. There were also 10 patients (14 eyes) who did not receive any eyedrops at all.

After six months, 90 percent of the eyes treated with NAC eyedrops experienced a 7 to 100 percent improvement in best corrected visual acuity (or best distance vision with eyeglasses or contact lenses), and 88.9 percent of the group demonstrated a 27 to 100 percent improvement in glare sensitivity.

However, recent scientific reviews believe that “there is currently no convincing evidence that NAC reverses cataract, nor prevents progression of cataract” and that more high-quality studies are needed to validate the use of carnosine eye drops for cataracts.

4. Gastrointestinal Disorders

Polaprezinc is an orally bioavailable chelate composed of zinc, and L-carnosine that is said to have potential gastroprotective, antioxidant, anti-ulcer and anti-inflammatory abilities. Oral supplementation with polaprezinc has been shown to increase the expression of a number of beneficial antioxidant enzymes, including superoxide dismutase, heme oxygenas, glutathione S-transferase, glutathione peroxidase and peroxidredoxin-1 in the gastric mucosa, which protect cells against reactive oxygen species.

Studies are ongoing, but so far results have been mixed when it comes to zinc caronsine for GERD with one 2016 study showing no difference between taking zinc L-carnosine and a placebo. Again, more studies are needed but some research does point toward the helpful use of zinc carnosine for leaky gutH. pylori and gastric ulcers.

5. Aging

If you read online reviews, you will likely see people claiming their skin looks more youthful after taking this supplement. Is that possible?

L-carnosine skin-boosting effects may occur due to this chemical compound’s anti-inflammatory, antioxidant and free radical scavenging properties, which help to protect DNA cells and hence boost skin health.

Risks, Side Effects and Interactions

L-carnosine is generally considered safe when taken by mouth for short periods of time or when used by adults on the skin. However, there can be rare side effects, including rash, itchiness, dry mouth, changes in appetite, feelings of tiredness or vivid dreams.

Rare but severe possible zinc carnosine side effects include decreased white blood cells, disorder of the digestive system and sideroblastic anemia. Less severe side effects may include stomach cramps, indigestion and nausea.

Recommendations range from 50 to 1,000 milligrams a day.

Unless you have an extremely low-protein diet, supplementation is often not warranted since the carnosine in food sources, such as beef, is so bioavailable. When the proper protein sources are consumed, bodily levels of carnosine have been shown to rise quickly (within a few hours).

Read product labels carefully, but it’s usually advised that carnosine can be taken with or without food. However, you should never take supplements containing zinc on an empty stomach.

The effectiveness of oral supplementation is questionable since most carnosine absorbed from the gut is destroyed in the bloodstream by enzymes called carnosinases. This is another big reason why it’s important to check with your healthcare provider before supplementing.

According to the National Institutes of Health, “Healthy children and adults do not need to consume carnitine from food or supplements, as the liver and kidneys produce sufficient amounts from the amino acids lysine and methionine to meet daily needs.”

And yet, the reviews show people who feel they are getting benefits, and its emphasized in articles that not much research has been done.


@I originally bought this product for the blood sugar balancing effect that it was recommended for. I have not noticed improvement necessarily for that, however, much is being said on the anti-aging benefits and I feel that this is the only new product I have introduced in the past month that I feel could contribute. I am 43 years old and had started to develop the noticeable wrinkles in my forhead and between my eyes as well as some crows feet around my eyes. My skin has improved, just after using one 90 capsule container as well as the clarity of my complexion. For the first time EVER I was told how beautiful my complexion is, and how smooth and clear it looks! I am ordering my second bottle today!

@ Skin noticeably tightened and me and my wife look several years younger. Also when we take two tablets per day my ears and those of my wife turn bright red. If we reduce our dosage to one tablet a day our ears gradually become more like pink/diluted red, but the skin also is not as taut.

@I have used this carnosine supplement previously for about six months and noticed my facial skin was looking positively younger and had a great glow to it. I was certainty getting comments to this effect, so it does definitely have a positive effect on skin collegene; However you need to persistant and take this supplement consistently for at least three or four months to show this effect.

~ I didn’t notice any difference in my health and well-being as a result of taking this supplement either for a few days or for many weeks. Actually, one of the very few noticeably effective supplements I’ve ever bought from iHerb and will continue to buy is Thorne Advanced Nutrients multivitamin. I surprisingly do feel better, more alert, more charged and energised within an hour of taking 2-3 capsules, which is less than half the recommended dose. this is a very rare effect for me.

For anyone over 50 in particular, when the ability to regenrate and repair DNA slows down. Increases mitochondrial production. It is subtle; slowly but surely my stamina improved.

My medical examination showed that L-carnosine would enhance my health (together with ornithine). Well, it did!!! After only 2 days I had a lot of energy. This definitely gives me my life back!I have tried many different L-carnosine products and this one from Jarrow Formulas raises above all others. It seems stronger and more potent, even causing this mild and brief tingling sensation in my hands/feet.

I started using carnosine to relieve tinnitus – it had gotten quite loud and even worse, my ears seemed to become very sensitive to noise. This product seems to have helped a lot with this problem – my tinnitus is in control and the hypersensitivity issue is gone. Any other carnosine product I have tried has not worked and therefore this is the one that I keep recommending to people.

When I started taking this, several people mentioned in the first week, that my skin looks so good, and they didn’t even know I had started taking Carnosine. It was very subtle, but I just felt better overall. Also, at my routine eye exam appointment, my doctor commented that no one had ever gotten a 100% on the vision field test before. He said that I even received a 100% on the margin of error portion. Quite remarkable. I told him that it must be the Carnosine I am taking. 🙂 He is a skeptic and wouldn’t accept that but I tend to think it must have something to do with it.

May be helpful for chronic fatigue and depression.

Gives a noticeable feeling of healthy energy.

These seem helpful in clearing brain fog and lowering blood sugar. They are generally indicated to fight whole body aging. I take them along with acetyl l carnitine and dmae.

I found out that Beta-Alanine is the limiting factor in the body’s own production of Carnosine, so I use that now. There’s nothing wrong with this product except that it’s 3 times more expensive than going with Beta-Alanine.

I have Post-Polio Syndrome and my muscle weariness has been cut in half with L-Carnosine.

L-Carnosine is needed to build stem cells especially after fasting, it’s a building block for the whole body .

Jarrow brand Seems to be more powerful than others. Noticeable difference in skin appearance and hair. Does semm to have a youthening effect.

great for memory, vision

This made me go to bathroom a lot. Kidney was getting uncomfortable and pain. I got better after 3 days stop this L Carnosine. I expected this come from food base.

It optimizes the functioning of healthy cells and helps in slowing down aging, acts as an antioxidant, neutralizes free radicals. Regjunenates, heals, gives energy. A miracle supplement.

With systematic use, the following effect is expected: general well-being improves; the development of age-related diseases is significantly reduced; age-related changes are corrected, appearance improves; the risk of developing cardiovascular diseases is reduced; aging slows down; performance improves and energy is added; improves memory and attention, sleep. In the process of taking, the cell life level increases up to 413 days. While the duration without the drug is 139 days. Energy and the ability to divide also return. As a result, there is a kind of “transition” from the state of aging to rejuvenation. The substance has an antioxidant effect, promotes the destruction of free radicals, stabilizes cell membranes, and stimulates the production of collagen. In addition, it removes salts of heavy metals and neutralizes excess glucose.

L-carnosine is found in the brain, heart, skin, muscles, kidneys and stomach, which supports the normal aging and renewal process of the cellular system. L-carnosine optimizes the functioning of healthy cells and helps to slow down aging by neutralizing free radicals and thus acting as an antioxidant, including in the brain and nerve cells. Composition L-carnosine 1000 mg

oday L-carnosine is recognized as one of the most effective anti-aging ingredients among all known to science. I have been using it for a long time, so I look at my 43 at most 35. People who regularly use carnosine may look younger and feel better. Like me!)

`I’ve found L-carnosine to be quite effective for the skin’s aging processing, in addition, to helping with focus. I’ve been taking this for quite some time.

(Jarrow 1000mg) This is carnosine that works. I bought in a lower dosage and did not feel much effect. and I tried this one with my mother. and we “feel the difference”. a surge of strength, energy. of the minuses, I could not sleep for a long time.

L-Carnosine is a dipeptide found in the brain, heart, skin, muscles, kidneys and stomach , which supports the normal aging process and renewal of the cellular system. L-carnosine optimizes the functioning of healthy cells and helps to slow down aging by neutralizing free radicals and thus acting as an antioxidant, including in brain and nerve cells.

I found out about this supplement on the Internet, after reading positive reviews, I decided to try it. I take carnosine two capsules twice a day, two weeks after the start of the intake I felt a surge of strength and energy, my mood improved, I think it will only get better, I recommend buying.

carnosine inhibits the growth of amyloid fibrils, which are formed, for example, in Alzheimer’s disease.

The child has an ASD. Constantly jumping in place and waving his arms like a butterfly. 7 years ago I learned that l-carnosine helps with autism. I started giving. ACh decreased significantly almost immediately. For 7 years now I have been giving 1 capsule with food every day (I open it and pour it into the porridge). As soon as I stop giving, ACh come back. So I highly recommend it for ASD!

Carnosine is a dipeptide, an amino acid residue that plays a very important role in rejuvenating the body. It regulates the ph of the body, affects the metabolic processes in the cell. It also has antioxidant properties. It is a chelator. Therefore, I decided to choose it for my difficult struggle with gray hair)) in addition to this, I replenish iron deficiency and work with bile. Well, I didn’t remove my gray hair, but as if I began to feel better. I advise. Take on an empty stomach in the morning, like all amino acids. Food only one hour after ingestion.

Since my work is physical labor, I tend to get tired and it was hard to get up in the morning, but since I started taking this three times a day, I have become much less tired.

It is said to help for the brain, dementia and ADHD.

Carnosine has anti-glycation and anti-carbonyl properties that can help reduce sugar damage to the body.

Carnosine has shown itself well in removing edema in the body

I take to support mitochondrial dysfunction and antioxidant processes, when taken, I feel an improvement in overall well-being and an increase in energy.

Improved sleep, and energy in the day.

excellent additive for the regeneration of the walls of the gastrointestinal tract

Doctor recommended for healing after a stroke.

Better than pine b ark.

Great product for gastrointestinal problems

For hypthyroidism this ones a worker.

good for fatigue

As a graduate student, I participated in experiments on mice studying carnosine. We gave carnosine to “fast-growing mice” (normal mice live for about 2 years, and mice of this line managed to grow old and die within 8-10 months). Those mice that received carnosine from birth (instead of water they had carnosine solution in their drinkers) also lived for 8-10 months, but in old age they looked better, there were fewer senile symptoms, especially less cataracts. This is statistically significant. I saw it myself with my own eyes. So I decided that using carnosine is a good idea. Actually, in order to have an effect, it should be consumed for life and preferably in horse dosages. But I began to use 2 capsules per day. I did not count on any effect. Since the effect should manifest itself in 20-30 years as Im in my 20s
