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.

Skin Carotenoid Levels
Skin carotenoid levels measured via a portable Veggie Meter, Longevity Link Corp. device using reflection spectroscopy on a participant's fingerprint.
Time frame: From enrollment to the end of treatment at 8 weeks for Cohort-1 and 12 weeks for Cohort-2
Antioxidant Levels
Antioxidant levels assessed by a Samsung Watch device via skin absorption spectra. The bioactive sensor measures reflected light after emitting LED light. The test requires the participant to press the thumb on the sensor for a few seconds to get a reading.
Time frame: From enrollment to the end of treatment at 8 weeks for Cohort-1 and 12 weeks for Cohort-2.
