Synopsis

Source of validity: Scientific
Rating (out of 5): 2

N-Acetyl Carnosine (NAC) is used primarily in the form of eye drops, with claims that it can help treat or delay the progression of cataracts and other age-related eye problems. The rationale for its use is based on its antioxidant properties, as oxidative stress is a known factor in the development of cataracts and other ocular diseases. Some small clinical trials, particularly those conducted in Russia and published in the early 2000s, have suggested that NAC eye drops may improve lens clarity and visual function in people with cataracts. However, these studies have notable limitations, including small sample sizes, short durations, and lack of independent replication. Systematic reviews and regulatory agencies such as the U.S. FDA have not recognized NAC as a proven treatment for eye disease, and high-quality, large-scale randomized controlled trials are lacking. While there is a plausible scientific mechanism and some preliminary human data, the overall strength of evidence is currently low, and more robust research is needed before NAC can be considered an evidence-based intervention for eye problems.
