Our exploration focused on the potential of N-Acetyl Carnosine (NAC) in treating cataract, a condition that occurs when proteins in the eye become insoluble and form large masses. Traditional cataract surgeries often require expensive equipment and skilled mediators, so we sought a less invasive solution through the use of solid lipid nanoparticles (SLN).
We prepared SLN-NAC using a unique method known as Mill's method, resulting in particles measuring around 75 nanometers—the ideal size for effective eye penetration. The formulation demonstrated a sustained release of the active ingredient over 24 hours, following a rapid initial release after just one hour.
Our studies also indicated that SLN-NAC penetrated the cornea more effectively than standard NAC eye drops, while corneal hydration tests showed no damage to corneal cells. This suggests that SLN-NAC may offer a promising breakthrough in cataract treatment by enhancing drug delivery and minimizing toxicity.
Overall, the compelling results lead us to believe that SLN-NAC could significantly improve the way cataracts are treated, offering a practical alternative to surgical interventions.
We aimed to understand how L-carnosine affects cataract formation, looking specifically at its potential as an anticataractogenic agent. To do this, we assessed L-carnosine through various laboratory tests that measured its ability to counteract oxidative stress and its effects on lens tissue.
Although marketed for its antioxidant properties, our findings revealed that L-carnosine is primarily a strong antiglycating agent, rather than a potent antioxidant or metal-chelating agent. In our tests using human lens cells, we found that there were no significant changes in cell survival when exposed to L-carnosine compared to controls, which suggests that it may not have a significant protective effect in these scenarios.
Interestingly, when we treated whole porcine lenses with L-carnosine in a high galactose environment—which is known to promote cataract formation—we observed a marked reduction in the formation of harmful compounds related to glycation. This indicates that L-carnosine holds promise for future treatment options for diabetic cataracts and other conditions driven by glycation, if not primarily through antioxidant mechanisms.

Carnosine aids in cataract prevention
Protective effects of carnosine on dehydroascorbate-induced structural alteration and opacity of lens crystallins: important implications of carnosine pleiotropic functions to combat cataractogenesis.
We explored the impact of dehydroascorbate (DHA) on the structure and functioning of lens crystallins, specifically looking at the protective role of l-carnosine against cataract formation. Our research revealed that high levels of DHA in lens tissue can lead to significant protein unfolding and aggregation, both of which are key contributors to age-related cataracts.
During the study, we observed that l-carnosine, an endogenous dipeptide, effectively preserved the natural structure of lens proteins even when faced with the challenges posed by DHA. This is crucial since maintaining the stability of these proteins could help prevent the development of cataracts as we age.
Interestingly, while DHA alters the chaperone activity of α-crystallin—a protein important for lens clarity—carnosine was found to restore its functionality. Additionally, we noted that carnosine helped combat the increased instability of lens proteins modified by DHA, thereby enhancing their resilience.
Our lens culture assessments further illustrated that DHA does cause significant lens opacity, a condition that carnosine successfully mitigated. The findings underscore carnosine's valuable properties, particularly its abilities to prevent glycation and aggregation, which may play significant roles in slowing down cataract formation, especially in oxidative stress conditions.

I attempted to reverse my cataract with CAN-C eye drops and saw measurable improvement after 3 months (from 20/50 to 20/25 in my better left eye). However, after starting L-Carnosine, my vision became blurrier, negating the benefits of the eye drops. This was alarming, so I stopped L-Carnosine and am now using only CAN-C eye drops to reverse my cataract.

Promising cataract treatment mixture
[Deceleration of cataract development in rats under the action of N-acetylcarnosine and D-pantethine mixture].
We explored the impact of a mixture of N-acetylcarnosine and D-pantethine on cataract development in rats induced by UV-A light. The study utilized instillation of a 5% mixture into the eyes or intraperitoneal injections of varying doses, aiming to observe the mixture's protective effects starting from the 82nd day of the experiment. Notably, we observed that the combination significantly inhibited cataract formation, especially as the study progressed.
UV-A exposure increased the content of water-insoluble proteins in the lens, which is commonly associated with cataract development. However, the use of the mixture effectively prevented this rise, showcasing its potential in cataract treatment. Interestingly, we also noted that the proteins were categorized into three fractions and that UV-A reduced one fraction while increasing others. The combined treatment not only mitigated these changes but demonstrated properties similar to chaperones, which help in maintaining protein structure.
Overall, while the study indicates a positive effect of this specific mixture on cataract development, it doesn't allow us to evaluate the effects of l-carnosine alone given the presence of D-pantethine in the mixture. Thus, while promising, further research is needed to establish the effectiveness of l-carnosine by itself in preventing cataracts.
This product seems to be helping with my cataract. Although it’s still a bit early to fully celebrate, it does appear to be making a difference.

This powerful antioxidant combats protein glycation, which accelerates ageing. I take it in two-month courses multiple times a year and use it in eye drops and lens injections to slow cataract progression. It pairs well with Taurine and Alpha Lipoic Acid for vision support.
A cataract is a clouding of the eye's natural lens, which is located behind the iris and pupil. This lens is responsible for focusing light onto the retina, allowing us to see clearly. With a cataract, the lens becomes opaque, leading to blurred or distorted vision, difficulty with glare, and sometimes even colors appearing faded. Cataracts typically develop slowly and can affect one or both eyes. They are most commonly associated with aging, but other factors, such as genetics, certain medical conditions, medications, and even prolonged exposure to ultraviolet light, can also contribute to their formation.
While cataracts are generally a part of the aging process, they can be treated effectively through surgical intervention. The surgery involves removing the cloudy lens and often replacing it with an artificial intraocular lens, allowing for improved vision. Most patients experience significant improvement in their sight following surgery, and it is considered one of the most common and safest procedures performed worldwide. If you're experiencing symptoms of cataracts or are concerned about your vision, it's essential to consult an eye care professional for proper evaluation and personalized treatment options.
L-Carnosine is a naturally occurring dipeptide composed of two amino acids, beta-alanine and L-histidine. It is primarily found in high concentrations in muscle and brain tissues, where it plays a role in various biological functions. L-Carnosine is known for its potential antioxidant properties, helping to protect cells from oxidative stress and damage caused by free radicals. Additionally, it is believed to have a buffering effect on pH levels in muscles, which may enhance athletic performance and delay fatigue during intense exercise.
Research surrounding L-Carnosine has suggested it may contribute to healthy aging by promoting cellular function and reducing age-related decline. Some studies indicate that it could support cognitive function and may even have potential benefits for conditions such as Alzheimer’s disease. However, it's important to note that while L-Carnosine can be obtained through dietary sources, supplementation and its effects should be approached with caution, as more research is necessary to fully understand its benefits and any potential interactions with other medications. If you're considering adding L-Carnosine to your health regimen, consulting with a healthcare professional is advisable.
Based on user reviews, the timeframe for seeing results from this supplement for cataracts can vary. For some users, noticeable improvements in eye health occurred relatively quickly, with one reviewer expressing satisfaction with improvements after beginning Carnosine supplements. However, others reported that while results are achievable, they require a longer duration of consistent use, with one user stating that persistence over a period of six months yields satisfactory outcomes Read Review.

Therefore, if you're considering this supplement for cataracts, you might anticipate seeing results anywhere from a few weeks to several months.
Research suggests that supplements containing carnosine, particularly in the form of N-acetylcarnosine (NAC), may hold promise as preventive measures against cataract formation. Several studies, such as one focusing on the protective role of NAC delivered via solid lipid nanoparticles, indicated improved drug delivery to the eye and enhanced effectiveness in treating cataracts compared to traditional methods [2]. Moreover, other research has shown that NAC can improve visual functions and offer protective benefits against oxidative stress, a critical factor in cataract development [14]. These findings position carnosine and its derivatives as potential candidates for both the prevention and treatment of cataracts.
Additionally, studies have highlighted carnosine's ability to stabilize lens proteins and counteract damaging glycation processes that are commonly involved in cataract formation [4][9]. While further research is warranted to fully understand the standalone efficacy of carnosine, particularly L-carnosine, the collective evidence supports its role in promoting eye health and mitigating cataract risk, particularly for individuals at higher risk such as diabetics [1]. Thus, while supplements like NAC may not replace surgical interventions, they could serve as beneficial adjuncts for maintaining lens clarity and overall visual health.
Users have reported various improvements in symptoms related to cataracts after using Carnosine supplements. Many individuals express satisfaction with noticeable enhancements in their eye health, with one user specifically stating, "I have seen a noticeable improvement in my eye health" following a recommendation from their ophthalmologist Read Review. Additionally, some users have noted improvements in their overall vision quality, indicating that the product has played a role in their cataract management Read Review.
It's worth mentioning that while some users experience positive results relatively quickly, others have found that these benefits tend to manifest over an extended period with consistent use. One reviewer emphasized that "persistence over six months yields satisfying outcomes" when used in conjunction with proper eye medication Read Review. Therefore, while many individuals report beneficial effects from Carnosine, it is crucial to remember that results can vary significantly based on personal health factors and adherence to a dosing regimen.
Users have reported positive experiences when combining Carnosine supplements with other nutritional aids for managing cataracts. One reviewer highlighted the benefits of pairing Carnosine with Taurine and Alpha Lipoic Acid, stating that this combination supports vision effectively Read Review. This synergistic approach appears to enhance the overall impact on eye health, suggesting a multi-supplement strategy may yield beneficial results for individuals facing cataract-related issues.
Additionally, some users emphasized that consistent use of Carnosine, perhaps alongside other appropriate eye medications, can significantly contribute to cataract management. One reviewer noted that while the results require time and persistence, integrating Carnosine with proper eye care tactics leads to satisfying improvements over several months Read Review. Overall, it seems that users find value in supplement combinations to optimize their eye health outcomes.
When it comes to tackling cataracts, research suggests that a 1% concentration of N-acetylcarnosine (NAC) eye drops shows promising results. This formulation has demonstrated the ability to enhance visual function, improve visual acuity, and reduce glare sensitivity in individuals with cataracts, effectively offering a non-invasive alternative to traditional surgical interventions [6]. Moreover, N-acetylcarnosine benefits from its unique properties as a prodrug of L-carnosine, which engages in antioxidant activity and helps in mitigating oxidative damage that contributes to cataract formation [15].
While L-carnosine itself has been investigated for its protective qualities against cataract development, the current consensus leans towards the efficacy of its derivative, N-acetylcarnosine, applied in a 1% concentration as the optimal choice for individuals seeking to manage cataract-related issues. Continued research is essential to further define the impact of L-carnosine alone, but current findings emphasize the advantages of N-acetylcarnosine formulations for their superior ocular absorption and therapeutic benefits [14].

l-Carnosine shows potential for cataracts
Novel intraocular and systemic absorption drug delivery and efficacy of N-acetylcarnosine lubricant eye drops or carcinine biologics in pharmaceutical usage and therapeutic vision care.
Our investigation delved into the beneficial effects of l-carnosine in treating cataracts, focusing on its delivery through specially formulated lubricant eye drops. We utilized a meta-analysis from phase 2 randomized double-blind placebo-controlled clinical trials to gather comprehensive data on how well this treatment works.
The drops contained 1% N-acetylcarnosine, which is a prodrug of l-carnosine, designed to enhance corneal absorption. We discovered that the l-carnosine absorbed in the eye showcased various pharmacological benefits, particularly in preventing and even reversing cataract formation.
Furthermore, we noted that systemic absorption of l-carnosine activated key brain areas involved in vision, improving sensory pathways related to sight. In addition, the treatment displayed a good safety profile, minimizing inflammation in the eyes post-treatment without any toxicity to surrounding structures.
Overall, our findings support the potential of l-carnosine not only for managing cataracts but also as a neuroprotective agent that safeguards vision under stress conditions.

Carnosine aids in cataract prevention
Protective effects of carnosine on dehydroascorbate-induced structural alteration and opacity of lens crystallins: important implications of carnosine pleiotropic functions to combat cataractogenesis.
We explored the impact of dehydroascorbate (DHA) on the structure and functioning of lens crystallins, specifically looking at the protective role of l-carnosine against cataract formation. Our research revealed that high levels of DHA in lens tissue can lead to significant protein unfolding and aggregation, both of which are key contributors to age-related cataracts.
During the study, we observed that l-carnosine, an endogenous dipeptide, effectively preserved the natural structure of lens proteins even when faced with the challenges posed by DHA. This is crucial since maintaining the stability of these proteins could help prevent the development of cataracts as we age.

Carnosine reduces cataract turbidity
Carnosine ameliorates lens protein turbidity formations by inhibiting calpain proteolysis and ultraviolet C-induced degradation.
We explored the role of carnosine, an endogenous peptide found in our lenses, in mitigating cataract formation. Through several in vitro models, we investigated how carnosine protects lens proteins from damage caused by calpain-induced proteolysis and from ultraviolet (UV) light exposure.
In our experiments, we measured turbidity, a cloudiness representative of cataract formation, by assessing the optical density of lens proteins. We found that increasing concentrations of carnosine significantly reduced turbidity in samples after exposure to heat and UV-B light, suggesting its protective qualities against these stressors.
Specifically, carnosine showed strong inhibitory effects on calpain activity, which is known to break down lens proteins. Furthermore, it reduced aggregation of γ-crystallin, a key protein in the lens, upon exposure to UV-C radiation. Overall, our findings indicate that carnosine stands out as a potential treatment for cataracts by enhancing lens protein stability and reducing degradation, especially in UV-C conditions.
These results suggest an exciting avenue for further research into carnosine as a natural protective agent against cataracts, potentially paving the way for effective treatments in the future.

Carnosine protects lens proteins
Carnosine Prevents Different Structural Damages Induced by Methylglyoxal in Lens Crystallins.
We explored the protective effects of l-carnosine on lens proteins when faced with methylglyoxal (MGO), a compound that increases in concentration in the eyes of diabetic patients and is known to contribute to cataract formation. By treating eye lens proteins with MGO while introducing carnosine, we actively sought to determine whether carnosine could mitigate the structural damage that MGO causes.
Our experiments, which included sodium dodecyl sulfate polyacrylamide gel electrophoresis and fluorescence assessments, revealed that MGO significantly alters the structure of lens proteins. We observed that this damage leads to the formation of new chromophores, which are indicative of structural changes. However, when carnosine was present, we noted a marked reduction in these protein changes, suggesting a significant protective role for carnosine against MGO-induced damage.
Consequently, our findings propose that carnosine could be a valuable preventive measure against diabetic cataracts in humans, highlighting its potential as a dietary supplement in eye health.

We examined the potential of N-acetylcarnosine, a prodrug that converts to L-carnosine, as a new treatment for cataracts. This study delved into how N-acetylcarnosine enhances ocular drug delivery through its activation via enzymatic processes in the eye. According to our findings, N-acetylcarnosine acts as a powerful antioxidant while also promoting the removal of damaging sugar molecules linked to cataract formation.
Through various clinical methods, including visual acuity tests and photography, we aimed to assess the effectiveness of N-acetylcarnosine eye drops in preventing and treating cataracts and other eye diseases. Importantly, our research highlighted that the effectiveness of this treatment relates closely to the specific formulation of the eye drops used.
The results documented in our study suggest that the therapeutic benefits observed might largely stem from the antioxidant and transglycating properties of N-acetylcarnosine, promoting better eye health among individuals coping with cataracts. Overall, while the initial results show promise, we noted that the treatment's success greatly depends on the proper formulation, rather than isolating L-carnosine's effects alone.
