Antioxidants for AMD and Cataracts

Antioxidants work to neutralize the effect of free

radicals and help ward off (or at least slow) many age-related conditions.

They do this by protecting your cells from damage and general “wear

and tear.” Since your eyes are as susceptible to aging as your

other organs, it stands to reason that taking antioxidants can protect

your eyesight. Studies have shown that two eye diseases, age-related

macular degeneration (AMD) and cataracts, have responded particularly

well to antioxidant supplementation.

In October 2001, researchers unveiled the results of the Age-Related

Eye Disease Study (AREDS), a ten-year study conducted at eleven

different medical centers across the country. After testing 3,640

men and women aged 55 to 80, researchers found that those patients

who took daily antioxidant supplements (500 mg of vitamin C, 400

IU of vitamin A, and 25,000 IU of beta-carotene) had a 17 percent

lower risk for developing AMD. Similarly, patients who took zinc

supplements (80 mg as zinc oxide with 2 mg of copper as cupric oxide)

had a 21 percent lower risk for developing AMD, while those patients

who took both the antioxidants and zinc had a 25 percent lower risk

for developing advanced AMD.

A similar study published in the October 1999 issue of Archives

of Ophthalmology supports these findings. Researchers from France

tested over 2,500 patients to determine if the use of antioxidants

could provide protection against macular degeneration. They found

that the participants who consumed the greatest amount of vitamin

E reduced their risk for advanced AMD by an incredible 82 percent.

According to the November 2000 issue of Archives of Ophthalmology,

long-term antioxidant use may also reduce your risk of cataracts.

Researchers interviewed more than 3,000 adults aged 43 to 86. They

found that those participants who took a multinutrient containing

vitamins C or E for more than a decade had a 60 percent lower risk

of developing cataracts than those who didn’t take the multi, regardless

of other risk factors. Researchers hypothesized that the antioxidant

properties of certain vitamins and minerals may help to retard cataract


To prevent the formation of AMD and cataracts, I recommend taking

a good, daily multinutrient containing zinc (10 mg) and selenium

(50 mg), as well as the antioxidants beta-carotene (25,000 IU),

vitamin E (400 mg), and vitamin C (at least 500 mg).
