Brief Summary
A randomized, double-blind, placebo controlled, cross-over trial to investigate the effect of the Investigational Product "DailyColors™" (DC) on age-related pathways in adults. The aim of this study is to measure the effects of acute treatment with DC on key pathways relevant to healthy ageing using blood biomarkers. Based on power calculations a sample size of 20, is sufficient to detect an effect size of 0.46 at a power \> 90%. To account for dropout the investigators will include 26 subjects in total.
