NCT01162174

Brief Summary

The investigators hypothesize that acute consumption of Oligonol, a patented lychee fruit extract (Amino Up Chemical Co.) particularly rich in low molecular weight flavanols, will improve endothelial function, reduce platelet reactivity and increase circulating levels of flavonoids after a single intake.
