• Athletic performance. Most available research suggests that oral tart cherry modestly improves muscular strength and endurance when compared with control. However, most studies are limited by a high risk of selection bias. Details: A meta-analysis of 14 small studies involving a total of 303 trained athletes and untrained healthy adults shows that tart cherry might modestly improve recovery of muscular strength and power when compared with control. Also, some subgroup analyses show that tart cherry may improve recovery of jump height and sprint time when compared with control (105629). In another meta-analysis of 10 studies involving 147 marathon runners, cyclists, or triathletes at various levels of training, taking tart cherry juice concentrate or powder 1.5 hours before exercise, or for up to 7 days prior to exercise, seems to improve exercise endurance, as measured by the time to complete an exercise trial, when compared with control (102340). However, both analyses have a high risk of selection bias and some analyses have high heterogeneity. Specific products assessed in the meta-analyses include tart cherry juice (CherryActive, Active Edge Nutrition) 60 mL, 90 minutes prior exercise (98699); a specific tart cherry concentrate (CherryActive, Active Edge Nutrition) 30 mL twice daily for 8 days (93149); and a specific freeze-dried tart cherry supplement (CherryPURE, Shoreline Fruit LLC) 480 mg daily 7 days before, on the day of, and 2 days after exercise (93158).

INSUFFICIENT RELIABLE EVIDENCE to RATE

• Aromatase inhibitor-induced arthralgia. It is unclear if oral tart cherry is beneficial in patients with aromatase inhibitor-induced arthralgia (AIIA). Details: Preliminary clinical research in a small group of females with non-metastatic, hormone-receptor positive breast cancer and AIIA after taking aromatase inhibitors for at least 4 weeks shows that taking tart cherry juice concentrate 30 mL daily for 6 weeks reduces pain scores on a visual analog scale by about 35%, compared with 1% in those taking placebo (109657).
• Cognitive function. It is unclear if oral tart cherry improves cognitive function. Details: Preliminary clinical research in healthy, middle-aged adults shows that taking tart cherry juice concentrate 30 mL orally twice daily for 3 months reduces mental fatigue and improves performance on tests evaluating sustained attention, psychomotor speed, and alertness when compared with placebo. However, it does not affect sleep quality or cerebral blood flow (109655).
• Exercise-induced muscle soreness. Research on the use of oral tart cherry juice or supplements for the reduction of exercise-induced muscle soreness is conflicting. Details: A meta-analysis of 12 small studies in trained athletes and untrained healthy adults shows that tart cherry might modestly attenuate delayed muscle soreness after exercise involving maximal muscle contractions or maximal effort sprints when compared with control. However, tart cherry juice seems to be no better than placebo for improving delayed muscle soreness after prolonged aerobic exercise (105629). These findings are limited by a high risk of selection bias, high heterogeneity, and imprecision. Some products assessed in the meta-analysis include a specific Montmorency tart cherry concentrate (Holland & Barrett Ltd.) 30 mL twice daily for 5 days before, on the day of, and for 2 days after intermittent sprint exercises (102341); a specific freeze-dried tart cherry supplement (CherryPURE, Shoreline Fruit LLC) 480 mg daily for 7 days before, on the day of, and 2 days after running a half-marathon or doing back squats (93157,93158); a specific Montmorency tart cherry juice concentrate (CherryActive, Active Edge Nutrition) 30 mL diluted in water and taken twice daily for 8 days (93149,93151,101880,102344); and a specific juice (Sour cherry juice, Cherrypharm Inc.) containing 90% tart cherry juice and 10% apple juice as a sweetener, twice daily (93152,93154). Some individual clinical studies have yielded mixed findings. One clinical study in professional rugby players shows that taking a Montmorency tart cherry juice concentrate gel, 30 mL (equivalent to 100 cherries) twice daily for 2 days before, on the day of, and for 2 days after a match does not improve muscle soreness when compared with placebo (102339). Similarly, in male professional soccer players, taking tart cherry juice, 60 mL before and after a 90-minute match and then 12 and 36 hours later, does not improve subjective muscle soreness when compared with placebo (102342). Also, a small study in healthy males shows that taking a specific tart cherry supplement (Tart Cherry Extract Powder NordicCherry, Specnova, LLC.) 500 mg daily for 7 days prior to performing resistance exercise does not reduce muscle soreness when compared with placebo (105631). In contrast, a small clinical study in recreational long-distance runners shows that drinking a specific tart cherry juice (Cherrish, Cherrish Corp.) 10.5 ounces twice daily for 7 days prior to a long-distance race decreases post-race muscle pain by around 65% when compared with placebo (93156). Reasons for the discrepancies may include differences in tart cherry products, the small number of subjects, and heterogeneity in study populations and evaluated endpoints. In some studies, the subjects' normal diets were continued during the study, whereas in others, a reduced polyphenol diet was consumed for the duration of the study (102342,105629).
• Exercise-induced respiratory infections. It is unclear if oral tart cherry juice reduces the risk of exercise-induced respiratory infections. Details: A small clinical study in recreational athletes shows that drinking a specific juice blend (Sour cherry juice, Cherrypharm Inc.), containing 90% tart cherry juice and 10% apple juice as a sweetener, 8 ounces twice daily for 5 days before, on the day of, and 2 days after running a marathon, decreases the risk for upper respiratory tract symptoms such as cough, sore throat, congestion, and sneezing when compared with placebo (93168).
• Fibromyalgia. It is unclear if oral tart cherry improves symptoms in patients with fibromyalgia. Details: A very small clinical study in females with fibromyalgia participating in an eccentric exercise program shows that taking a specific tart cherry concentrate (Cherrish, Cherrish Corp.) 10.5 ounces twice daily for 14 days does not improve pain or muscle strength when compared with placebo (93192).
• Gout. It is unclear if oral tart cherry juice reduces symptoms of gout; research is conflicting. Details: Preliminary clinical research shows that tart cherry juice lowers serum urate and increases urinary urate excretion in healthy people, as well as people with hyperuricemia that has not progressed to gout (93166,102338). However, in patients with gout, taking Montmorency tart cherry juice concentrate (Cherryvite) in doses of 7.5-30 mL twice daily for 28 days does not affect urate excretion or the frequency of gout flares (102343). A small, unblinded clinical study in adults with chronic gout shows that taking a combination product (GoutFighter, MaxBiocare Pty Ltd.) containing tart cherry fruit extract 100 mg, celery seed extract 300 mg, devil's claw tuber extract 150 mg, folic acid 90 mcg, potassium citrate 50 mg, and ascorbic acid 50 mg orally, as 2 tablets twice daily for 45 days, modestly reduces mean serum uric acid levels and reduces perceived pain and frequency of joint swelling when compared to baseline (106488). The validity of these findings is limited by the lack of a comparator group. Additionally, it is unclear if any effects are due to tart cherry, other ingredients, or the combination.
• Hypertension. It is unclear if oral tart cherry juice reduces blood pressure; research is conflicting. Details: A very small clinical study in males with mild hypertension shows that taking 60 mL of a specific tart cherry concentrate (CherryActive, Active Edge Nutrition) modestly decreases systolic, but not diastolic, blood pressure 1-3 hours after consumption when compared with placebo (93155). This finding is limited by the small study size and the use of a single dose. Another small study in healthy adults without hypertension shows that drinking 30 mL of Montmorency tart cherry concentrate (Cherry Marketing Institute) diluted in 240 mL of water daily for 3 months does not reduce blood pressure when compared with baseline or placebo (105633).
• Insomnia. Small clinical studies suggest that oral tart cherry juice may modestly improve sleep and reduce insomnia. This effect might be due to the melatonin content in tart cherry juice. Details: A small clinical study in healthy adults less than 40 years of age shows that consuming a specific tart cherry juice concentrate (CherryActive, Active Edge Nutrition) 30 mL standardized to contain 1.42 mcg/mL of melatonin twice daily for 7 days modestly increases total sleep time and efficiency when compared with placebo (17199). Another small clinical study in adults aged 65 years and older with chronic insomnia shows that drinking a specific juice blend (Sour cherry juice, Cherrypharm Inc.), containing 90% tart cherry juice and 10% apple juice as a sweetener, 8 ounces twice daily for 14 days, modestly improves insomnia severity, but not sleep latency, when compared with placebo (17403).
• Metabolic syndrome. It is unclear if oral tart cherry juice improves cardiovascular or metabolic biomarkers in patients with metabolic syndrome. Details: A very small study in patients with metabolic syndrome shows that drinking Montmorency tart cherry juice 30 mL diluted in 100 mL water daily for 7 days seems to reduce fasting insulin levels, but not blood pressure, when compared with drinking an equicaloric fruit-flavored placebo (105627). Another very small study in adults with metabolic syndrome shows that drinking tart cherry juice 240 mL twice daily for 12 weeks does not improve glycemic control, lipid levels, blood pressure, or weight loss or when compared with a placebo juice (105632). These findings are limited by the small study size and short duration of use.
• Osteoarthritis. It is unclear if oral tart cherry juice is beneficial in patients with osteoarthritis. Details: A small clinical study in patients with osteoarthritis shows that drinking a specific juice blend (Sour cherry juice, Cherrypharm Inc.) containing 90% tart cherry juice and 10% apple juice as a sweetener, 8 ounces twice daily for 6 weeks, does not improve pain, stiffness, function, walking speed, or acetaminophen use when compared with placebo (93160). The validity of this finding is limited because the trial was not adequately powered to detect small differences between groups. More evidence is needed to rate tart cherry for these uses.
