What is it
Sour cherry ( Prunus cerasus , also called tart cherry or Montmorency cherry) is a deciduous fruit tree in the Rosaceae family, native to Europe and southwest Asia and widely cultivated for juice, concentrate, and powder products. The fruit is exceptionally rich in anthocyanins (notably cyanidin-3-glucosylrutinoside and cyanidin-3-rutinoside), other flavonoids (quercetin, kaempferol), hydroxycinnamic acids (chlorogenic and neochlorogenic acid), and naturally occurring melatonin. These polyphenols inhibit cyclooxygenase-1 and -2 and scavenge reactive oxygen species, accounting for the anti-inflammatory and antioxidant effects investigated in supplementation studies.

exercise-induced muscle damage and recovery
Supplement benefitTart cherry anthocyanins inhibit COX enzymes and scavenge reactive oxygen species, and randomized trials and meta-analyses show modest reductions in muscle soreness and faster recovery of strength after strenuous exercise. Effects are most consistent when started a few days before and continued around the event. The benefit is moderate rather than large.
Bottom line: Tart cherry modestly speeds recovery and reduces soreness around hard exercise.
gout flares and serum urate
Disease adjunctObservational and small interventional studies associate cherry intake with fewer gout flares and modest effects on serum urate. The data are largely observational or from small trials, so confidence is low and it is not a replacement for urate-lowering drugs. It may serve as an adjunct.
Bottom line: Cherry intake may reduce gout flares, but evidence is limited and it is not a primary therapy.
sleep quality
Supplement benefitSmall trials report modest improvements in sleep duration and efficiency with tart cherry juice, sometimes attributed to its polyphenols and effects on tryptophan availability. Its natural melatonin content is very low (~13 ng per 30 mL), so melatonin alone is unlikely to explain any effect. Evidence is preliminary.
Bottom line: Tart cherry may slightly improve sleep, but the effect is small and evidence preliminary.
blood pressure and oxidative stress
Biomarker supportSome small studies show modest short-term reductions in blood pressure and improvements in oxidative-stress markers after tart cherry intake. These are biomarker and short-term physiological changes from limited data, not demonstrated reductions in cardiovascular events. Confidence is low.
Bottom line: Tart cherry produces small biomarker-level changes in blood pressure and oxidative stress, with unproven clinical impact.
