The goal of the clinical study is to evaluate the impact of daily use of a dietary supplement TF Vista containing AREDS2 formula ingredients, astaxanthin (Haematococcus pluvialis) microalgae, bilberry (Vaccinium myrtillus) fruit powder and black currant (Ribes nigrum) fruit powder organic on skin carotenoid levels over an 8-week period for a Cohort 1(n= 20 participants) and 12 weeks for a Cohort 2 (n= 4 participants). Results will be compared using two devices - the Veggie Meter and the Samsung Watch - both of which utilize reflection spectroscopy technology. For Cohort 2 (n = 4 participants), in addition to assessing skin carotenoid levels, the study will also evaluate changes in macular pigment optical density (MPOD) before and after supplementation.
