New evidence that popular dietary supplement may help prevent, treat cataracts
July 15, 2009 -- Researchers
are reporting evidence from tissue culture experiments that the popular
dietary supplement carnosine may help to prevent and treat cataracts, a
clouding of the lens of the eye that is a leading cause of vision loss
worldwide. The study is scheduled for the July 28 edition of ACS’ Biochemistry, a weekly journal.
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 say.
