About

The present study examined the effect of Montmorency tart cherry juice and capsules on functional and blood-based cardio-metabolic markers in humans with Metabolic Syndrome. Participants received a single bolus of Montmorency tart cherry juice, Montmorency tart cherry capsules and placebo in a random, crossover trial. Outcome variables were measured immediately pre- and up to 5 hours post-bolus. It was hypothesised that Montmorency tart cherry juice and capsules would improve cardio-metabolic markers. Furthermore, it was hypothesised that Montmorency tart cherry capsules would be more beneficial than Montmorency tart cherry juice due to increased bioavailability of phytochemicals.
