What this Trial Is About
Researchers are evaluating the effects of a 12-week dietary supplement regimen on skin health and overall perceived physical health in healthy Chinese adults aged 18 and above who have low daily fruit and vegetable intake. This randomized, double-blind, placebo-controlled trial aims to explore the combined impact of antioxidants and nutritional supplements on skin condition and general well-being, without verifying the approved health functions of the products. Participants will be randomly assigned to one of two groups: one group will take a combination of Vitamin C & Green Tea Capsules and Multivitamin & Mineral Capsules twice daily, while the other group will receive a matching placebo combination with the same appearance and taste. The study duration is 12 weeks with scheduled assessments at baseline, 4, 8, and 12 weeks. During the study, participants will undergo detailed skin assessments including facial imaging, skin elasticity, moisture, gloss, hemoglobin levels, moisture loss, and skin carotenoid index measurements at four timepoints. Questionnaires will evaluate skin condition, physical health, psychological state, memory, and self-perceived health status. Height and weight will be measured at baseline and study end. The trial will monitor changes in skin and health status throughout the 12 weeks under close observation.
