Recent Study Shows that Popular Eye Disease Supplements May Benefit from a Tweak
August 15, 2014
Millions of older Americans who take special vitamin and mineral supplements to slow progression of a blinding condition called age-related macular degeneration should take note of a new study: It shows that adding omega-3 fatty acids to the mix probably won't help, but that replacing beta-carotene with two other nutrients lutein and zeaxathin may be beneficial.
This is the mainpoint of a complex study recently published in the Journal of American Medical Association.
The results are important because they concern the leading cause of blindness in the United States and popular supplements commonly sold as the "AREDS" formula — short for the Age-Related Eye Disease Study. In 2001, that study showed that a high-dose combination of vitamins C and E, beta-carotene, zinc and copper reduced the risk of worsening AMD by 25% when it was taken by people who already had intermediate AMD or advanced AMD in one eye.
