The "7,000 mg" on the front of this tart cherry bottle is not the amount in the capsules: the Supplement Facts panel shows a two-capsule serving contains 700 mg of a 10:1 extract, and 7,000 mg is the weight of fresh fruit that extract represents. Tart cherry (Prunus cerasus, usually the Montmorency variety in research) is a sour cherry rich in anthocyanins, sold as capsules for sleep, exercise recovery and joint comfort. The research is real but mostly on juice, and two trials of tart cherry capsules and powder found no effect on sleep.
Key Takeaways
- A 2025 systematic review of 7 interventional studies found 3 reported better sleep indicators and 3 reported higher melatonin, but with "large differences in dose, duration of intervention, and characteristics of the participating populations" and evidence described as "limited and heterogeneous."
- A 2024 crossover trial of 34 people with sleep problems taking 500 mg tart cherry capsules an hour before bed for 14 days found "no significant effects" on any sleep or inflammation measure.
- For exercise recovery, a 2021 meta-analysis of 14 studies found a small reduction in muscle soreness (effect size −0.44, 95% CI −0.87 to −0.02); a 2026 meta-analysis of 19 trials of juice found mixed results and certainty of evidence from "very low to moderate."
- A 2026 meta-analysis of 4 trials (392 people) found tart cherry lowered serum uric acid only modestly (SMD −0.22, 95% CI −0.43 to −0.01).
- The label lists 7,000 mg per 2-capsule serving "from 700 mg of 10:1 extract," so each capsule holds 350 mg of extract; the store's short description says 7,000 mg per capsule.

What Is Tart Cherry, and What Did the Studies Test?
Tart cherries are sour cherries, and the research on them mostly uses Montmorency tart cherry juice or concentrate. The 2025 sleep review notes they contain "active compounds such as melatonin and anthocyanins that may be effective in improving sleep quality." A key point for anyone buying capsules: much of what is known comes from drinking juice, often two 240 mL bottles a day in one trial, rather than from a small dose of dried extract. The studies below say which form they tested, and it matters.
Sleep: Mixed Reviews, Two Null Capsule Trials
Sleep is the first claim in this product's name and the one people most often ask about. The 2025 systematic review in Food Science & Nutrition (Barforoush and colleagues) pooled seven interventional studies: three reported significant improvements in sleep duration, efficiency or onset time, three reported increased melatonin after tart cherry consumption, and two reported reduced inflammatory markers such as CRP. It concluded that tart cherry "may be effective" but "the available evidence is still limited and heterogeneous."
Two trials tested the capsule and powder forms directly, and neither found a sleep benefit:
| Trial | Design | Result |
|---|---|---|
| Tucker et al., Nutrients, 2024 | 34 people with sleep issues and overweight or obesity; Montmorency tart cherry capsules (500 mg) or placebo one hour before bed for 14 days; crossover | No significant effects on total sleep time, deep or REM sleep, questionnaires, or inflammation markers (p > 0.05 for all); authors suggest testing higher doses |
| Hillman et al., Nutrition and Health, 2022 (print issue 2026) | 44 participants; two 240 mL bottles of juice or two capsules of powdered tart cherry per day, or placebo, for 30 days | No significant differences in sleep time or quality between groups, though both increased over 30 days; blood pressure unaffected |
The second trial's design is revealing: it tested juice as well as capsules and found no sleep difference for either, while sleep improved over 30 days in the placebo groups too, which is what you would expect when people track their sleep and expect to improve. The authors wrote that their results "conflict with previous data on MTC and sleep." These trials are small and their products differ, so they are not the last word, but they mean positive results from earlier juice studies should not be assumed to carry over to a capsule, or even to juice. If sleep is the goal, our melatonin article covers the most-used sleep supplement and its label problems.
"Despite the potential benefits of antioxidants and melatonin, we did not find improvements in sleep time or quality, cellular health or BP in participants consuming MTC for 30 days ..."
— Hillman et al., Nutrition and Health, 2022 (randomized trial, 44 participants)Cleveland Clinic's short video on tart cherry juice for sleep, the form most of the research tested.
Exercise Recovery: A Small, Uncertain Effect
The best evidence for tart cherry is for recovery after strenuous exercise, and it is modest. A 2021 meta-analysis in the International Journal of Sport Nutrition and Exercise Metabolism (Hill and colleagues) pooled 14 studies of tart cherry supplementation:
| Outcome | Effect size (95% CI) | Reading |
|---|---|---|
| Muscle soreness | −0.44 (−0.87 to −0.02) | Small benefit |
| Muscular strength recovery | −0.78 (−1.11 to −0.46) | Moderate |
| Muscular power | −0.53 (−0.77 to −0.29) | Moderate |
| C-reactive protein | −0.46 (−0.93 to −0.00) | Small; interval reaches zero |
| Interleukin-6 | −0.35 (−0.68 to −0.02) | Small |
| Creatine kinase; TNF-α | No significant effect | |
A newer 2026 meta-analysis in Sports Medicine – Open (Daab and colleagues) looked specifically at tart cherry juice in trained athletes across 19 trials and was more cautious. It found significant improvement in the recovery of maximal voluntary contraction strength, with substantial heterogeneity (I² 69–93%), reduced CRP up to 48 hours, but no significant pooled effects for muscle soreness, creatine kinase, IL-6 or TNF-α. It also noted that "statistical significance at selected time points ... was influenced by individual studies" and rated the certainty of evidence as very low to moderate. If you are comparing sports supplements, our pre-workout ingredients article grades others one at a time.
Uric Acid and Joints
The product name also says "Joint," and the store copy mentions joint comfort. The relevant research is on uric acid, the compound behind gout. A 2026 meta-analysis in the Asia Pacific Journal of Clinical Nutrition (Zhang and colleagues) pooled four randomized trials (eight comparisons; 392 people) and found tart cherry intake was associated with "a modest reduction in serum uric acid concentration" (standardized mean difference −0.22, 95% CI −0.43 to −0.01), with substantial heterogeneity, and concluded that "evidence is limited in quantity and consistency." That is a lab marker, not proof of fewer gout attacks or less joint pain. For joint supplements with larger trials, see our glucosamine and chondroitin article and our turmeric article.
Inside Amazing Formulas Tart Cherry Extract
Amazing Formulas Tart Cherry Extract is a bottle of 200 capsules. The Supplement Facts panel lists a serving of two capsules, with 100 servings per container, containing tart cherry extract (Prunus cerasus, fruit) listed as 7,000 mg "from 700 mg of 10:1 extract," with no established Daily Value. The front of the bottle reads "7,000 mg per serving." Other ingredients are gelatin (the capsule), magnesium stearate, silicon dioxide and rice flour. The label directs adults to take two capsules daily, preferably with a meal, which makes the bottle a 100-day supply. It is made in the USA and distributed by Amazing Nutrition of South Hackensack, New Jersey.
Here is the arithmetic the front label leaves out. A 10:1 extract means roughly 10 parts of fruit were concentrated into 1 part of extract, so 700 mg of extract corresponds to 7,000 mg of fruit. What you swallow is 700 mg of extract per serving, or 350 mg per capsule. The label does not state an anthocyanin amount, a melatonin amount, or which cherry variety was used, so it cannot be matched to the Montmorency products studied. The capsule is gelatin, which matters to vegetarians and vegans.
A correction, for accuracy: this store's short description says the product provides "the equivalent of 7000 mg of fresh tart cherries ... per capsule." The label says 7,000 mg per two-capsule serving, from 700 mg of extract, so each capsule is 350 mg of extract (3,500 mg fruit equivalent). The store's longer description correctly says "the equivalent of 7000 mg of tart cherry in two capsules." We have used the label throughout.
| This product | Typical trial dose | NIH RDA / AI | Tolerable Upper Limit | |
|---|---|---|---|---|
| Tart cherry extract | 700 mg of 10:1 extract per 2-capsule serving (7,000 mg fruit equivalent); 2 capsules daily | 500 mg powder before bed for 14 days (null sleep trial); two 240 mL bottles of juice daily; two capsules of powder daily for 30 days | None: not an essential nutrient | None established |
Tart cherry has no recommended intake and no Tolerable Upper Intake Level because it is a fruit extract, not an essential nutrient. No authority has set a limit, which is not the same as higher doses having been shown to be safe; follow the label's two capsules a day.
What the listing claims versus what the evidence supports: the store copy says tart cherry "guard[s] the body against oxidative stress and promote[s] healthy aging" and that it "provide[s] a small amount of natural melatonin, supporting joint comfort, post-exercise recovery, and restful sleep cycles." Those are manufacturer statements. The reviewed evidence supports a small recovery effect, and the newest review, of juice only, rates its certainty very low to moderate; sleep results are mixed, with two null trials of capsules and powder; the label states no melatonin amount; and the joint claim rests on a modest uric acid effect.
Who Might Consider It, and Who Should Skip It
Who this is for: adults who train hard, are curious about a low-risk recovery aid, understand the effect is small and uncertain, and have checked with a clinician if they are pregnant, nursing or on medication (the label advises it).
Who should skip it: anyone under 18 (the label says not for use); anyone pregnant, nursing or taking medication without medical advice; vegetarians and vegans, because the capsule is gelatin; anyone buying it mainly for sleep, given two null capsule and powder trials; anyone treating gout with it instead of medical care; and, frankly, most people, who could try tart cherry juice instead, the form tested in all 19 trials of the 2026 recovery review.

View Product DetailsFrequently Asked Questions
Does tart cherry help you sleep?
Possibly, but not reliably. A 2025 review of seven studies found three reported better sleep, with large differences between studies. Two recent trials of tart cherry capsules and powder found no sleep benefit versus placebo.
Does tart cherry help muscle recovery?
A little. A 2021 meta-analysis of 14 studies found a small reduction in muscle soreness (effect size −0.44) and moderate strength recovery benefits. A 2026 meta-analysis of juice trials found mixed results and very low to moderate certainty of evidence.
What does "7,000 mg" mean on the label?
It is the fresh-fruit equivalent, not the capsule content. The panel says 7,000 mg comes from 700 mg of 10:1 extract per two-capsule serving, so each capsule contains 350 mg of extract. The store's short description wrongly says per capsule.
How many tart cherry capsules should I take?
No official dose exists. This label directs two capsules daily, preferably with a meal, which is 700 mg of extract. A 500 mg powder dose before bed did not improve sleep in one trial. Follow the label or your clinician's advice.
Does tart cherry contain melatonin?
Tart cherries contain some melatonin, according to the 2025 sleep review, and three of seven studies reported raised melatonin levels. This label does not state a melatonin amount, so the quantity in these capsules is unknown.
Does tart cherry lower uric acid or help gout?
Modestly, for uric acid. A 2026 meta-analysis of four trials (392 people) found a small reduction (SMD −0.22, 95% CI −0.43 to −0.01), with limited evidence. It did not show fewer gout attacks, so do not replace prescribed gout treatment.
Is tart cherry extract vegan?
Not this one. The label lists gelatin as the capsule material, which is an animal-derived ingredient. The store's listing does not mention this. Tart cherry juice or a vegetarian-capsule product would suit vegetarians and vegans.
Is tart cherry juice better than capsules?
Neither has been shown to be better. A 2026 meta-analysis found 19 recovery trials of tart cherry juice in athletes alone, but sleep results are mixed for both forms, and a 2022 trial that tested both found no sleep benefit from juice or capsules. Juice also adds calories and sugar.
