Tart Cherry for Muscle Recovery After Exercise

Does tart cherry help muscles recover after exercise? The clearest answer from the research is about strength. A 2026 scoping review of 28 clinical trials on Montmorency tart cherry found that 7 of the 14 studies measuring strength recovery reported a significant benefit. In the best-known of those, 14 men lost 22 percent of their arm strength over four days after a damaging workout on placebo, and only 4 percent on tart cherry juice.

Soreness and performance are less settled. Six of 22 soreness studies and 4 of 10 performance studies found a significant effect. The rest did not, or found trends that did not reach significance.

So tart cherry is not a magic recovery drink, and nobody serious says it is. But it is one of the few foods with two decades of controlled human trials behind it. Here is what those trials did, in whom, and what they found.

Key studies at a glance

Why a cherry would do anything for sore muscles

Hard or unfamiliar exercise causes tiny tears in muscle fibers. The body responds with inflammation and a burst of oxidative stress, which is part of how muscle repairs and adapts, but it is also what you feel as stiffness and soreness a day or two later, and what shows up in blood as creatine kinase, interleukin-6 and C-reactive protein.

Montmorency tart cherries are rich in anthocyanins, the pigments that make the fruit red, along with other polyphenols. In lab studies these compounds act as antioxidants and dampen inflammatory signaling. The hypothesis behind every trial below is that taking them around a hard effort softens that inflammatory response enough to speed recovery without blocking it. Processing matters here because heat degrades anthocyanins, which we cover in cold-pressed vs heat-dried tart cherry.

The 2006 Vermont trial: 14 men, 22 percent strength loss versus 4

The study that started the field was published in the British Journal of Sports Medicine by Declan Connolly at the University of Vermont. Fourteen male college students drank 12 fluid ounces of a tart cherry juice blend or a placebo twice a day for eight days. On day four they did two sets of 20 maximal eccentric bicep contractions, the lengthening kind that causes the most damage. Strength, pain, tenderness and resting elbow angle were measured for four days after. Two weeks later they repeated the whole thing with the other drink and the other arm.

Strength loss averaged over the four days was 22 percent on placebo and 4 percent on cherry juice. Pain was also significantly lower on the juice. Muscle tenderness and elbow angle were not different.

The limits: 14 young men, a single arm exercise, and a disclosure that each author held 2.5 percent equity in the juice company. The strength finding has since been repeated by independent labs, which is why it still gets cited.

One of those independent repeats came from London South Bank University in 2011. Bowtell and colleagues gave 10 well-trained men Montmorency cherry juice concentrate or a fruit concentrate placebo for 7 days before and 48 hours after 10 sets of 10 single-leg knee extensions. At 24 hours the cherry group was back to 90.9 percent of its starting strength versus 84.9 percent on placebo, and a blood marker of oxidative damage to proteins rose by 24 percent versus 83 percent. Creatine kinase did not differ, and 10 people is a small trial.

The 2010 marathon study: 20 runners, strength back faster

Glyn Howatson's group at Northumbria University in the UK tested tart cherry juice around a real marathon. Twenty recreational runners took either the juice or a placebo for five days before the race, on race day, and for 48 hours after. The researchers tracked muscle damage (creatine kinase, soreness, isometric strength), inflammation (interleukin-6, C-reactive protein, uric acid), total antioxidant status and markers of oxidative stress.

Isometric strength recovered significantly faster in the cherry group. Interleukin-6, C-reactive protein and uric acid were all lower after the race. Total antioxidant status was about 10 percent higher across all post-supplement measurements. Creatine kinase and soreness, however, were not significantly different between groups. So strength and blood markers moved; how sore the runners felt did not, at least not enough to measure in 20 people.

Running pain: 54 relay runners, 7 days of juice

Soreness did move in a bigger trial from Oregon Health and Science University, published in 2010. Kuehl and colleagues gave 54 healthy runners, 36 men and 18 women averaging 36 years old, either tart cherry juice or a placebo cherry drink in 355 mL bottles twice a day for seven days before a 24-hour relay race and on race day. Each runner covered about 26 km over the day.

Both groups hurt more after the race, but the cherry group's pain rose by 12 mm on a 100 mm scale compared with 37 mm for placebo. That is one of the larger soreness effects in the literature and in a group of normal, non-elite runners. The design was randomized, double-blind and placebo-controlled. The main limit is that pain was self-reported, and the placebo was a cherry-flavored drink rather than nothing at all.

Team sports show a similar pattern. In a 2016 Northumbria University trial, 16 semi-professional soccer players took 30 mL of Montmorency tart cherry concentrate or a placebo twice a day for 8 days, with a long repeated-sprint shuttle test on day 5. Strength, jump height and agility recovered faster and soreness ratings were lower in the cherry group, and IL-6, an early inflammation signal, rose less. Creatine kinase did not differ, and with 8 players per group it is another small study.

Capsules instead of juice: the Texas A&M trials

Almost every early trial used juice or concentrate. In 2015 Levers, Kreider and colleagues at Texas A&M tested powdered Montmorency tart cherry in capsules, published in the Journal of the International Society of Sports Nutrition. Twenty-three healthy, resistance-trained men around 21 years old were matched for squat strength and body composition and randomized to 480 mg a day of powdered tart cherry or a placebo capsule for 10 days, including the lifting day and 48 hours after. The workout was ten sets of ten back squats at 70 percent of their one-rep max.

Quadriceps soreness was lower in the cherry group over time, significantly so in the outer quad at 24 hours and in the inner quad through 48 hours. Blood markers of muscle breakdown, including creatinine and total protein, rose less. Inflammatory markers and oxidative stress markers did not differ between groups. The authors concluded the capsules reduced soreness, strength loss during recovery and markers of muscle catabolism.

A follow-up from the same lab in 2016 gave the same 480 mg capsules to 27 endurance-trained runners and triathletes for 10 days around a half marathon. The cherry group finished 13 percent faster and had lower inflammatory and catabolic markers, though pre-run soreness also happened to be lower in that group, which complicates the recovery comparison. Both trials were double-blind and placebo-controlled, and both used a commercial powder with funding from the cherry industry.

What these two studies establish is that the effect does not depend on drinking juice. A dried powder in a capsule produced measurable changes at a dose far below the juice protocols. What they do not establish is which form or dose works best, because no one has run capsules against juice in the same people.

The 2026 scoping review: all 28 trials side by side

Published in Frontiers in Nutrition, the 2026 scoping review by Zhu, Smith and Cohn is the most complete map of this research. It gathered every clinical trial on Montmorency tart cherry and athletic performance, strength recovery or delayed-onset muscle soreness in healthy adults, 28 in total.

The tally: 7 of 14 strength recovery studies, 6 of 22 soreness studies and 4 of 10 performance studies reported a significant benefit. The authors' summary was that the evidence gives preliminary support for faster recovery of muscle strength, while findings on performance and soreness are mixed. They also noted that most trials were small and short, and called for larger randomized trials and a formal meta-analysis.

Two things to know when weighing it. The review was funded by the Cherry Marketing Institute, which also employed one of the authors, and the funder was involved in design and interpretation. And a scoping review counts studies rather than pooling their numbers, so "7 of 14" tells you how often a benefit was found, not how big it was.

Two meta-analyses do pool the numbers. A 2021 meta-analysis by Hill and colleagues combined data from 14 studies and found a moderate benefit for recovery of strength and power, a small benefit for soreness and for two inflammation markers, C-reactive protein and IL-6, and no effect on creatine kinase. A 2026 meta-analysis in Sports Medicine Open of 19 tart cherry juice trials in trained athletes found faster recovery of maximal strength and lower C-reactive protein up to 48 hours, but no pooled effect on soreness, and rated the certainty of the evidence very low to moderate. So the pooled data point the same way as the tally: strength is the most consistent finding, soreness the least.

What sports dietitians recommend

The Australian Institute of Sport, whose supplement framework is used by sports dietitians worldwide, classifies fruit-derived polyphenols including tart cherry as Group B: emerging or mixed evidence, worth considering in specific situations with individual monitoring. Its fact sheet lists recovery of strength and reduced soreness after damaging or endurance exercise as the outcomes with support, along with preliminary evidence for sleep (see tart cherry for sleep).

The practical protocol it describes: 90 to 200 cherries' worth a day, as juice, concentrate or capsulated powder, in a split dose, for four to seven days before and two to four days after the hard effort. It also gives two cautions. Cherries can have a laxative effect, so trial them outside competition first. And high daily doses of antioxidant and anti-inflammatory compounds may reduce the training adaptations athletes want, so it does not recommend them during ordinary day-to-day training. For an athlete chasing adaptation, that is a reason to use tart cherry around events. For someone over 50 whose goal is to get out of bed without stiffness after a long walk or a day in the garden, the trade-off is different, and daily use is what the comfort and sleep studies tested.

Where Nature Heart fits

Nature Heart Cold-Pressed Tart Cherry Extract is made from Montmorency tart cherry, the same variety in all 28 trials in the scoping review, in a capsule of dried cherry powder like the Texas A&M studies rather than juice. It is cold-pressed, not heat-dried, and standardized for anthocyanins. Two capsules a day give 3,600 mg equivalent of tart cherry. The capsule is a plain two-piece vegetable capsule, tart cherry is the only ingredient, and every batch is third-party lab tested before it ships. For details on choosing between forms, see capsules vs juice vs gummies.

We will not claim our capsules were in these trials; they were not, and the trials used their own products at their own doses. What we can say is what is in the bottle and that it is covered by a 90-day money-back guarantee, which is long enough to take it through a few hard weeks and judge for yourself.
