Effect of Orally Delivered Phytochemicals on Aging and Inflammation in the Skin

NCT03289832 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 25

No results posted yet for this study

Summary

The objective is to determine, in a small number of participants, the protective effects of UV-induced skin erythema (reddening or "sunburn") following oral administration of sulforaphane, curcumin, or a combination of the two plant (diet)-based supplements. The investigators will be using the over-the-counter nutritional supplements Crucera-SGS and Meriva-SF to deliver the biologically stable sulforaphane precursor and a highly bioavailable formulation of curcumin. Volunteers will be challenged with UV irradiation at 2-times the minimum erythematous dose (M.E.D.) on discrete 2 cm diameter circles on the upper buttocks. Skin redness will be monitored daily using a chromometer. Biomarkers will then be evaluated in blood, urine, and skin biopsies.

Interventions

DIETARY_SUPPLEMENT

Crucera-SGS

Crucera-SGS is a commercially available dietary supplement. The active ingredient is glucoraphanin, a phytochemical from broccoli and it is prepared as a simple extract of broccoli seeds. Glucoraphanin is converted to sulforaphane by bacteria in the human intestines. Crucera-SGS is formulated by Thorne Research Inc. into gel-caps that make it much more convenient to deliver than having subjects eat broccoli every day.

DIETARY_SUPPLEMENT

Meriva 500-SF

Meriva-SF is a commercially available dietary supplement. The active ingredient is curcumin, a phytochemical from the spice, turmeric, and it is prepared as a simple extract of this plant, formulated with lipids which aid in its absorption and metabolism. Meriva-SF is formulated by Thorne Research Inc. into gel-caps that make it much more convenient to deliver than having subjects eat turmeric powder every day.
