Tart Cherry

Montmorency tart cherry has a legitimate, meta-analysed benefit for recovery of muscle strength after hard exercise — small but real. Its popular use as a natural melatonin sleep aid is supported only by tiny pilot studies with marginal effects.

What the science says

  • Speeds recovery of muscle function after strenuous exercise Moderate evidence

    A systematic review and meta-analysis of tart cherry supplementation found a small but statistically significant benefit for recovery of muscular strength and power in the 24-96 hours after damaging exercise. Effects on perceived soreness were smaller and effects on inflammatory and oxidative-stress markers were inconsistent across studies.

  • Improves sleep Limited evidence

    In a pilot study of 15 older adults with insomnia, 240 mL of tart cherry juice twice daily for 2 weeks produced a modest reduction in minutes awake after sleep onset, with no change in sleep latency or total sleep time. Tart cherries contain melatonin, but at doses far below a typical melatonin tablet, so any hypnotic effect is likely small.

  • Modestly improves cardio-metabolic markers Moderate evidence

    A meta-analysis of randomised trials found tart cherry juice reduced systolic blood pressure and C-reactive protein by small amounts, with less consistent effects on lipids and glucose. These are surrogate markers over short trials, not demonstrated cardiovascular outcomes.

  • Reduces gout attacks Limited evidence

    Cherry intake lowers serum urate modestly and observational data associate it with fewer gout flares, but there is no adequately powered randomised trial. It should not replace urate-lowering therapy.

Dosage & safety

Studied doseRecovery protocols typically use 30 mL of Montmorency tart cherry concentrate twice daily (roughly equivalent to 90-100 cherries, supplying about 90-120 mg anthocyanins), started 4-7 days before and continued 2-3 days after the target event. Sleep studies used 240 mL of tart cherry juice twice daily for 2 weeks. Powdered capsule products vary widely in anthocyanin content and are not clearly equivalent.
SafetyVery safe as a food. The main practical issues are the sugar and calorie load of juice (roughly 120-140 kcal per 240 mL), and GI upset, bloating or loose stools from the sorbitol content in larger volumes. High anthocyanin intake could theoretically add to antiplatelet effects; be cautious around surgery if you drink large volumes. People with diabetes should count the carbohydrate. Because tart cherry blunts some exercise-induced inflammatory and oxidative signalling, there is a theoretical concern that chronic year-round use could dampen training adaptations, so periodising it around competition rather than taking it daily is reasonable.
