Indication: Visual acuity
Source: Nutrition, 2003;19:21-24.
Research: In a randomized, double-blind study, groups of five patients diagnosed with age-related cataracts took 15 mg of lutein from a lutein ester supplement, 100 mg vitamin E or a placebo capsule three times per week for up to two years. The subjects’ visual acuity was measured with several standard eye tests at the beginning of the study and then every three months.
Results: As a group, subjects taking the lutein ester supplements had significant improvements in visual acuity—approximately 63%—and glare sensitivity also improved. Those taking vitamin E showed a trend toward maintaining their acuity. The opposite effect was seen among those taking placebos; there was a trend toward decreased visual acuity in these subjects. During the supplementation period, cataracts did not progress in four patients in the lutein group, three patients in the vitamin E group and one patient in the placebo group.
