Tart Cherry
Evidence Fact Sheet
Prunus cerasus L., Montmorency
Tart cherry (Prunus cerasus, Montmorency) is an anthocyanin-rich botanical food studied for exercise recovery, sleep quality, attention and uric-acid/inflammatory markers. Meta-analyses support muscle-recovery benefits; blood-pressure effects are null. GRAS food in the US; no EFSA/ANVISA efficacy claim.
Also known as: Prunus cerasus · Montmorency cherry · Sour cherry · Vistula tart cherry
Overview
Tart cherry (Prunus cerasus L., cultivar Montmorency; also called sour cherry) is a polyphenol- and anthocyanin-rich fruit consumed as a juice, concentrate, or freeze-dried powder. Proposed mechanisms studied in research include NF-κB signaling inhibition, free-radical scavenging by anthocyanins, COX-2 inhibition, and naturally occurring melatonin acting on circadian signaling. Research protocols commonly use a concentrate at 30 mL twice daily (or diluted juice 240 mL twice daily) or freeze-dried powder around 480-500 mg/day, with recovery studies dosing across several days around exercise and sleep studies dosing about 1-2 hours before bed. In the US it is a conventional/GRAS food ingredient lawful under DSHEA (structure/function claims only, with the mandatory FDA disclaimer); it carries no EFSA-authorized health claim in the EU and no authorized functional claim under ANVISA.

Evidence-Based Benefits
Each benefit below is anchored to a specific PubMed-indexed study. Effect sizes, sample sizes, and p-values are reported as published; no values are inferred. Honest negatives and null results are kept alongside the positive findings, and disease-research populations are described as such — Tart Cherry is not characterized as a treatment for any disease.
Exercise recovery (muscle soreness & strength)
Meta-analysis supported- ES = -0.44muscle soreness · 95% CI -0.87, -0.02
- ES = -0.78strength recovery · 95% CI -1.11, -0.46
- 14 studiespooled trials
A systematic review and meta-analysis pooling 14 studies found tart cherry supplementation had a small beneficial effect on reducing muscle soreness and a moderate beneficial effect on recovery of muscular strength after strenuous exercise. This is the most consistently studied use case for tart cherry.
Reported effect: Muscle soreness ES = -0.44 (95% CI -0.87, -0.02); muscular strength recovery ES = -0.78 (95% CI -1.11, -0.46); 14 studies pooled.
“Tart cherry supplementation had a small beneficial effect in reducing muscle soreness (effect size [ES] = -0.44, 95% confidence interval [CI] [-0.87, -0.02]). A moderate beneficial effect was observed for recovery of muscular strength (ES = -0.78, 95% CI [-1.11, -0.46]). Data from 14 studies.”

- WMD = -0.4 pg/mlIL-6 · 95% CI -0.68, -0.11
- 10 trialspooled trials
A meta-analysis of ten trials in athletic populations found tart cherry juice significantly improved maximal voluntary isometric contraction (MVIC) and lowered the inflammatory cytokines IL-6 and IL-8 after exercise-induced muscle damage, supporting an anti-inflammatory contribution to recovery.
Reported effect: MVIC WMD = 9.13% (95% CI 6.42-11.84); IL-6 WMD = -0.4 pg/ml (95% CI -0.68 to -0.11); IL-8 WMD = -0.3 pg/ml (95% CI -0.6 to -0.0); 10 trials.
“Ten trials were included in the analysis. TCJ supplementation significantly improved MVIC [weighted mean difference (WMD) = 9.13%, 95% CI (6.42-11.84)], decreased IL-6 [WMD = -0.4 pg/ml, 95% CI (-0.68 to -0.11)] and IL-8 [WMD = -0.3 pg/ml, 95% CI (-0.6 to -0.0)].”

Blood pressure (honest negative) & CRP
Null / no benefit Meta-analysis supported- P > 0.05blood pressure · no effect
- WMD -0.39 mg/lCRP · 95% CI -0.74, -0.05
- 21 trialspooled trials
A GRADE-assessed meta-analysis of 21 trials found tart cherry did NOT significantly affect blood pressure, heart rate, high-sensitivity CRP, or IL-6 by the primary analysis (P > 0.05) — an honest negative for cardiovascular outcomes. A separate pooled estimate did show a modest reduction in serum C-reactive protein.
Reported effect: No effect on blood pressure, heart rate, hs-CRP, IL-6 (P > 0.05); serum CRP reduction WMD -0.39 mg/l (95% CI -0.74, -0.05; P = 0.024); 21 trials.
“Regarding the 21 included trials, tart cherry didn't affect blood pressure, heart rate, high-sensitive C-reactive protein, and interleukin-6 (P > 0.05)... it can reduce serum C-reactive protein (WMD: - 0.39 mg/l; 95% CI: - 0.74, - 0.05; P = 0.024).”

Sleep quality
RCT supported- p = 0.015total time in bed
- p = 0.044wake after sleep onset
- n = 19field hockey players
In a randomized controlled trial of 19 elite female field hockey players, short-term Montmorency tart cherry juice after intermittent exercise produced significant interaction effects on several sleep-quality measures (total time in bed, wake after sleep onset, movement index), although it did NOT change melatonin or cortisol levels — so the sleep benefit was not explained by measured hormones.
Reported effect: Significant interaction effects: total time in bed (p = 0.015), wake after sleep onset (p = 0.044), movement index (p = 0.031); n = 19; no significant melatonin/cortisol change.
“The individuals were divided into the placebo group (PLA, n = 9) and the tart cherry juice group (TCJ, n = 10)... The variables of sleep quality showed significant interaction effects with regards to the total time in bed (TTB; p = 0.015), wake after sleep onset (WASO; p = 0.044), and movement index (MI; p = 0.031) variables... A significant interaction effect (group × time) between PLA and TCJ groups was not observed in the levels of melatonin and cortisol.”

Uric acid & gout markers
Emerging / indexed- 6 studiessystematic review
A systematic review of six studies reported decreases in the incidence and severity of gout following cherry ingestion and a positive correlation between tart cherry juice and lower serum uric acid. The authors could NOT pool the data into a meta-analysis because of too few studies and high methodological variation, so the finding is directional and qualitative — effect size not extractable.
Effect size: this study reports the direction of the finding but does not state a specific numeric effect size, so none is given here rather than estimated.
“The six studies included in this systematic review reported decreases in the incidence and severity of gout following the ingestion of cherries... Overall, we observed a positive correlation between the consumption of tart cherry juice and a decrease in serum uric acid concentration... we were unable to conduct effective meta-analysis due to a lack of relevant studies and a high degree of variation in the methodologies and metrics used.”

Frequently Asked Questions
1. What is tart cherry best studied for?
The most consistent human evidence is for exercise recovery. A meta-analysis of 14 studies found a small beneficial effect on muscle soreness (ES = -0.44) and a moderate effect on muscular strength recovery (ES = -0.78), and a separate 10-trial meta-analysis found improved maximal voluntary contraction (WMD = 9.13%) plus lower IL-6 and IL-8. These are research findings in studied populations, not a treatment claim.
2. Does tart cherry actually help with sleep?
Some controlled research is supportive but mixed. In an RCT of 19 elite field hockey players, Montmorency tart cherry juice produced significant interaction effects on total time in bed (p = 0.015) and wake after sleep onset (p = 0.044), yet it did not change measured melatonin or cortisol — so any sleep benefit was not explained by those hormones. This is an emerging, not settled, area.
3. Does tart cherry lower blood pressure?
No — this is an honest negative. A GRADE-assessed meta-analysis of 21 trials found tart cherry did not significantly affect blood pressure, heart rate, high-sensitivity CRP, or IL-6 in the primary analysis (P > 0.05). The same review did report a modest reduction in serum C-reactive protein (WMD -0.39 mg/l), but the blood-pressure outcome was null.
4. Is tart cherry approved to treat gout or any condition?
No. In the US tart cherry is a GRAS/conventional food lawful as a dietary-supplement ingredient under DSHEA, allowing only structure/function claims with the mandatory FDA disclaimer; there is no FDA-authorized health claim, no EFSA-authorized claim in the EU, and no authorized functional claim under ANVISA. A systematic review of six studies noted directional links between cherry intake and lower uric acid and fewer gout flares, but the authors could not pool the data, so this remains qualitative evidence rather than a treatment indication.
