Tart cherry juice: what recovers and what does not

Tart cherry juice has a real literature and a narrow result. The most recent pooling of 19 trials in 385 trained athletes found maximal voluntary contraction recovering better at every time point after hard exercise, with heterogeneity between trials of 69 to 93 percent and certainty rated very low to moderate. In the same analysis, muscle soreness, creatine kinase, interleukin-6, TNF-alpha and range of motion showed no pooled effect at all. An earlier pooling of 14 trials had found small to moderate gains in soreness, strength, power and jump height, so the field has moved toward the cautious answer rather than away from it. The dose behind all of this is a supplement schedule. Most trials used about 30 mL of concentrate twice a day, or 236 to 355 mL of juice, started several days before the damaging session and continued after it, and no trial in the review adjusted the dose for body mass.

The numbers, per 100 g

What a real portion looks like

• The regimen behind the recovery results is thirty millilitres of concentrate twice a day, started days before the exercise. — 19 trials in trained athletes (n = 385) Evidence B source
  Seven trials used concentrate, five juice, four a juice blend, two powder and one a cherry beverage; servings were most often about 30 mL of concentrate or 236 to 355 mL of juice twice daily; protocols ran 4 to 10 days with a pre-loading phase before the damaging bout and continued intake after it; no included trial adjusted the dose for body mass

What your body absorbs

• Cherry phenolics do reach the body: their breakdown products show up in urine after a month of eating the fruit. — 34 and 29 healthy adults on their regular diet in the two fruit arms, plus 24 with no dietary change (n = 87) Evidence B source
  Resting whole blood chemiluminescence fell by 29.5% and fMLP-stimulated by 24.7% after 30 days in the cherry arm and remained lower after the 10-day washout (33.7% and 32.3%); urinary chlorogenic, 4-hydroxyhippuric and 3-hydroxyhippuric acids rose; apples and controls changed in neither
• Seven days of cherry concentrate raised melatonin in urine and lengthened sleep in twenty people. — 20 healthy adult volunteers (n = 20) Evidence B source
  Total melatonin content significantly elevated with cherry juice (P < 0.05) and unchanged on placebo; time in bed, total sleep time and sleep efficiency all rose (P < 0.05); the timing of the melatonin rhythm did not shift, only a trend to higher mesor and amplitude

What cooking and storage change

• The powdered capsule held uric acid down for a day, the juice for two hours, and then the juice pushed it back up. — 48 adults randomised across six groups (n = 48) Evidence B source
  Group by time interaction for uric acid p = 0.02; the fall lasted to 24 h for one capsule, to 8 h for two capsules and to 2 h for one juice dose, after which uric acid rose from 8 h to 48 h in the single juice group; average fall across groups 8%; no change in high sensitivity C-reactive protein (p = 0.64) or oxygen radical absorbance capacity (p = 0.42)

What it does to your health

• An earlier pooling of the same literature found small to moderate gains in soreness, strength and power. — 14 studies of adults performing strenuous exercise (n = 14 studies) Evidence A source
  Muscle soreness ES -0.44 (95% CI -0.87 to -0.02), muscular strength -0.78 (-1.11 to -0.46), muscular power -0.53 (-0.77 to -0.29), jump height -0.82 (-1.18 to -0.45), sprint time -0.32 (-0.60 to -0.04), C-reactive protein -0.46 (-0.93 to 0.00), interleukin-6 -0.35 (-0.68 to -0.02); creatine kinase and TNF-alpha showed nothing
• Outside exercise, tart cherry moved C-reactive protein by about half a milligram per litre and moved nothing else. — 10 randomised clinical trials in adults, none of them exercise recovery trials (n = 10 trials) Evidence A source
  C-reactive protein weighted mean difference -0.55 mg/L (95% CI -1.03 to -0.06, p = 0.029); interleukin-6 +0.08 pg/mL (-0.02 to 0.17, p = 0.10), not significant; TNF-alpha assessed in only three studies with no effect

What people believe that the data does not support

• Cherry does not lower blood pressure, and the trials testing it say so plainly. — 7 randomised controlled trials with 201 participants (n = 201) Evidence A source
  No significant decrease in either systolic or diastolic blood pressure
• Europe refused the joint claim for sour cherry, and refused every other cherry claim put to it. — — Evidence E source
  Six register entries name Prunus cerasus and all six carry the status Non-authorised: heart, joints, antioxidants, brain and memory, plus two traditional-use claims on renal elimination and digestion; authorised cherry claims in the EU number zero
• Calling cherries a rich source of antioxidants is the wording Europe specifically would not allow. — — Evidence E source
  The entry carries the status Non-authorised; the same register shows zero authorised claims for anthocyanins as a substance and seven refusals across anthocyanin-bearing foods

Who this works differently for

• A concentrated extract taken for four weeks cut urate by more than a third, but ten healthy adults took it. — 10 healthy adults, 6 male and 4 female, mean age 34.9 years (n = 10) Evidence C source
  Acute dosing changed neither C-reactive protein nor urate; after four weeks C-reactive protein fell 23.0% (-1.36 mg/L) and urate 37.4% (-2.62 mg/dL) against placebo, both p < 0.001

What is still unknown

• Tart cherry juice moved one recovery marker after hard exercise and left the rest where they were. — 19 trials published between 2006 and 2022 in trained athletes, 385 participants in total, 13 male-only cohorts, 1 female-only and 5 mixed (n = 385) Evidence A source
  Maximal voluntary contraction recovery improved at every time point (post ES 0.63, 24 h 1.12, 48 h 1.29, 72 h 2.14, 96 h 4.82) with heterogeneity of 69 to 93%; countermovement jump improved only at 48 h (ES 1.41); C-reactive protein fell up to 48 h (post -0.46, 24 h -0.73, 48 h -0.68); muscle soreness, creatine kinase, IL-6, TNF-alpha and range of motion showed no pooled effect
• Serum uric acid falls a little, on four trials, in people who do not have gout. — 4 randomised trials giving 8 comparisons, 392 participants (n = 392) Evidence A source
  Standardised mean difference -0.22 (95% CI -0.43 to -0.01) with substantial heterogeneity
• A month of cherry juice or capsules changed nothing about sleep, blood pressure or body composition. — 44 healthy adults with complete sleep records (n = 44) Evidence B source
  No difference in sleep time or quality between groups, though both improved over the 30 days; blood pressure unaffected; body mass fell by 0.70 kg in the placebo capsule group at 14 days and by 0.75 kg in the cherry capsule group between 14 and 30 days; no other change in body composition or cellular health

The bottom line

If you are taking it for gout, look at who was studied. Four trials giving eight comparisons in 392 people found serum uric acid lower by a standardised 0.22 with substantial heterogeneity, and those people did not have gout. Form matters more here than anywhere else on this page. In 48 adults, a powdered capsule held uric acid down for 24 hours, two capsules for 8 hours, and a single dose of juice for 2 hours, after which uric acid in the juice group climbed again from 8 to 48 hours. For sleep, two trials disagree and the larger one is the negative one. Seven days of concentrate raised total melatonin in urine and lengthened time in bed, total sleep time and sleep efficiency in 20 people, while 30 days in 44 adults found no difference in sleep time or quality against placebo, and no change in blood pressure. Blood pressure has its own answer: seven trials in 201 people, with no significant fall in systolic or diastolic. Europe has looked at six health claims for sour cherry and refused all six, including the joint claim and the wording about a rich source of antioxidants. Two practical notes. Tart cherry juice carries 13.7 g of carbohydrate per 100 g, so a recovery dose is also a sugar dose, and that is the part to plan around if you have diabetes. And outside sport, the honest number for inflammation is a fall in C-reactive protein of about 0.55 mg/L, with interleukin-6 unmoved.
