Researchers are investigating two over-the-counter nutritional supplements to find out whether the active ingredients (sulforaphane from broccoli and curcumin from the spice turmeric) can protect the skin from damage caused by aging and UV irradiation.
Healthy people ages 18 and 70 with Fitzpatrick skin type 1 or 2 (fair- to light-skinned, burns easily, tans rarely), who are nonsmokers and have not recently taken an antibiotic are eligible to participate. Volunteers will make 9-10 brief on-site visits during one month and have two blood draws and two sets of 24-hour urine collections, 10 days of oral supplements, and three weeks of cruciferous-free diet, controlled UV administration on buttock, and eight punch biopsies,
The study is located at Johns Hopkins Outpatient Center, East Baltimore. Compensation is $300.
