5. Study Description

Brief Summary
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.

Intervention Type
Dietary Supplement
Intervention Name(s)
Montmorency Tart Cherry Capsules
Intervention Description
Capsules are made from 100% natural, tart Montmorency cherries. Carefully prepared Montmorency cherry skins are freeze-dried and milled into a fine powder to protect the cherry phytonutrients and optimise absorbtion. This powder is then encapsulated into a 100% vegetarian shell.
Intervention Type
Dietary Supplement
Intervention Name(s)
Montmorency Tart Cherry Juice
Intervention Description
100% natural, tart Montmorency cherry concentrate (30mL) diluted with 100mL water. Concentrate contains no sweeteners, preservatives, flavourings or added sugar.
