Brief summary: An acute, randomized, placebo controlled, double blinded crossover study in health subjects. Participants will complete 4 intervention arms in random order consisting of a placebo control beverage, a high dose phenolic beverage, a high dose phenolic beverage combined with a fruit extract, and a low does phenolic beverage.
