What Is Tart Cherry Good For? The Montmorency Evidence by Outcome

Tart cherry is best supported for recovery after hard exercise: across 14 trials, Montmorency cherry taken for about a week around a race or heavy session reduced muscle soreness (effect size -0.44) and helped strength recover (-0.78), mostly at about 60 mL of concentrate a day.¹ Sleep rests on three small crossover trials of 20, 15 and 8 people with gains in minutes, and a 30-day trial of 44 that found none; gout on one observational study of 633 people in which cherries went with 35% lower odds of an attack; blood pressure on a 7 mmHg fall lasting three hours after a single 60 mL dose in 15 men, in a supplier-funded trial.^{7, 8, 9, 11, 13, 21} The fruit's melatonin is real but tiny, 13.46 nanograms per gram.¹⁰ No cherry health claim is authorised in Great Britain; potassium carries the only wording a label may use. This evidence map sits alongside the Wellgard sleep guide and the Wellgard ashwagandha guide.

Is tart cherry the same as Montmorency cherry and sour cherry?

Yes. Tart, sour and Montmorency cherry are the same fruit, Prunus cerasus, Montmorency being the variety the trials and most UK products use. Sweet cherries (Prunus avium) are a different species, and juice pressed from them is not what any study below used. Balaton is a second sour variety with a sixth of Montmorency's melatonin.¹⁰ If the label says only "cherry", check. The species, the varieties and what is in the fruit: what tart cherry is.

Does tart cherry help muscle recovery after exercise?

The strongest evidence, and still modest. A 2021 meta-analysis of 14 trials found a small effect on muscle soreness (effect size -0.44), moderate effects on recovery of strength (-0.78) and power (-0.53), a large effect on jump height (-0.82), small falls in two inflammatory markers and no change in a muscle-damage marker; most trials were small and in trained men.¹ Ten trials in 147 people, pooled separately, found endurance performance a little better (standardised mean difference 0.36).²

The trials give the doses. Twenty UK marathon runners drank cherry juice for five days before, on the day of and two days after the race: isometric strength recovered faster and interleukin-6, C-reactive protein and uric acid were lower.³ Fifty-four relay runners on 355 mL of juice twice a day for a week saw post-race pain rise by 12 mm on a 100 mm scale against 37 mm on placebo.⁴ Sixteen trained cyclists on 30 mL of Montmorency concentrate twice a day for eight days held their strength for 72 hours after a 109-minute race simulation.⁵ In nine water polo players a week of juice changed nothing; the authors blamed a sport that damages little muscle.⁶

Does tart cherry help you sleep?

Four small trials, one of them null, covered in full on do sour cherries help you sleep. In 20 healthy UK adults, a week of concentrate at 30 mL twice a day raised urinary melatonin and added about 25 minutes of sleep.⁷ In 15 older adults with insomnia, two weeks of a juice blend improved only time awake after falling asleep and insomnia severity, by effects the authors called "considerably less than" sleeping tablets or CBT for insomnia.⁸ In a supplier-funded trial of eight over-50s with sleep-lab-confirmed insomnia, 240 mL twice a day for two weeks added 84 minutes of recorded sleep.⁹ The fruit's melatonin is 13.46 nanograms per gram, about 1.3 micrograms per 100 g, a thousandth of a prescription dose; the authors now point to tryptophan availability as the likelier mechanism.^{9, 10} A 2025 systematic review found seven interventional studies in all, three reporting better sleep duration, efficiency or onset, with doses and durations too different to pool; a fourth trial, 44 healthy adults on juice or capsules for 30 days, found no difference in sleep time or quality against placebo.^{20, 21} What to drink before bed ranks the juice against the other bedtime drinks.

Is tart cherry good for gout and uric acid?

One observational study and, since 2020, randomised trials. In 633 people with gout followed for a year, eating cherries in the two days before a flare went with 35% lower odds of an attack (odds ratio 0.65), and cherries alongside prescribed urate-lowering medicine with 75% lower odds than neither; that is self-reported intake, not a trial.¹¹ The trials have not matched it. In 50 people with gout, placebo or 7.5 to 30 mL of concentrate twice a day for 28 days made no difference to serum urate, urinary urate or the number of flares.¹⁵ In 282 men starting prescribed urate-lowering treatment, urate fell to the same extent whether or not their alkalising mixture contained tart cherry.¹⁶ A 2026 pooled analysis of four randomised trials in 392 people found a small average fall in urate (standardised difference -0.22, with the interval reaching -0.01) and substantial differences between the trials.¹⁷ On single servings, 48 healthy adults given juice (240 mL) or capsules (480 mg) for 48 hours saw urate fall by about 8% within hours, in a study with no water control; against water, a single 250 mL serving made no difference in 12 adults, and urate fell through the day whatever they drank.^{12, 18} In a supplier-funded trial of 25 adults with raised urate, 960 mg powder capsules with a purine-rich meal, and two a day for a week, did not change the urate response.¹⁹ No juice "flushes" uric acid: the kidneys clear it, and the NHS says frequent attacks or high urate need uric acid-lowering medicine taken regularly, even when symptom-free.¹⁴ The trials, the 12-month study still to report and the NHS wording are set out on cherries and gout; what foods cause gout puts cherries next to the purine, alcohol and sugar evidence.

Does tart cherry reduce inflammation or lower blood pressure?

In the exercise trials, a little: pooled C-reactive protein (effect size -0.46) and interleukin-6 (-0.35) fell by small amounts, measured in the days around a race.¹ So "how long to reduce inflammation" has an answer only for exercise: the trials loaded for four to seven days and continued two or three days after. In 58 people with knee osteoarthritis, six weeks of a juice blend lowered a blood marker of inflammation but did not improve pain scores more than placebo.²² On blood pressure, in a supplier-funded trial, 15 men with early hypertension given a single 60 mL dose saw systolic pressure fall for three hours, peaking 7 mmHg below placebo at two hours.¹³ One dose, one afternoon; nobody changes a blood-pressure tablet on it. Over 30 days in 44 healthy adults, blood pressure did not change.²¹

How much tart cherry should you take, and when?

Match dose and timing to the outcome the trials measured.

So "how long until results" depends on the purpose: a week for recovery, one to two weeks for sleep, hours for urate, and the longest ran six and twelve weeks.

Juice, concentrate or capsules: which is better?

The same fruit at different strengths. Juice is pressed cherries, often diluted and sometimes sweetened; concentrate has had most of the water removed, so 30 mL stands in for roughly 240 mL of juice and is diluted at home; capsules carry a dried powder of the fruit. "From concentrate" juice is concentrate with the water put back: pre-diluted, not inferior. No trial has compared commercial products; formats differ in dose per serving and in sugar, both on the label, and what each form gives, trial by trial, is on juice, concentrate, extract or capsules.

Frequently asked questions

What is tart cherry?

The fruit of Prunus cerasus, the sour cherry; Montmorency and Morello are varieties of it, and sweet cherries are a different species. Species, varieties and what is in the fruit: what tart cherry is.

Is tart cherry juice a laxative?

It can loosen stools: cherries contain sorbitol, a sugar alcohol that draws water into the bowel, which is why large glasses do it and 30 mL of concentrate rarely does. No trial has tested tart cherry for constipation; the NHS constipation page lists other sorbitol fruits, fluids and fibre.²³

How long does tart cherry take to work?

By outcome, from the trials: recovery trials loaded four to five days before the event; the sleep trials measured after one and two weeks, and a 30-day trial found no difference; in gout, 28 days of concentrate changed nothing measurable, and the 12-month trial of attacks has not reported.^{1, 7, 9, 15, 21}

Which is better for inflammation, tart cherry or turmeric?

Tart cherry's inflammation data come from week-long exercise trials with small falls in C-reactive protein and interleukin-6; turmeric's curcumin has been trialled for weeks to months in people with joint pain, set out on how to take turmeric for inflammation.¹ No trial has compared the two.

Which is better, beetroot juice or tart cherry juice?

Beetroot juice is studied for its nitrate and endurance; tart cherry's endurance effect is smaller (standardised mean difference 0.36) and its main record is recovery afterwards.² No trial has set them against each other.

Should I drink tart cherry juice in the morning or at night?

The sleep and recovery trials split the dose, morning and an hour or two before bed.^{5, 7, 9} For a single daily serving no trial settles it; take it when you will remember.

Why do people drink sour cherry juice?

Recovery after running or the gym, gout, sleep and the taste, in that order of evidence: trials, an observational study, four small trials with one null.^{1, 7, 11, 21}
