Tart cherry
Taken by athletes to recover faster after very hard sessions or competitions. In small trials, strength came back a little sooner. Optional, not essential.
At a glance
| Our verdict | Optional for athletes after very hard sessions; small benefit, low certainty. |

Supplement Check
Is it right for you?
Tart cherry concentrate carries a real sugar load, and drug-tested athletes need batch-tested products. Your check looks at your health, your sport and everything else you take. Our Supplement Check looks at:
- Diabetes: use capsules, not concentrate (sugar)
- Drug-tested athletes: only a batch-tested product
- Under 18: outside the Supplement Check, which is for adults
Coming soon. The Supplement Check and the Online Health Assessment open once our safety testing is complete.
$59 when it opens, paid once. Adults 18 and over, anywhere in Canada. While the service is new, Dr. French reads every report himself, and your report arrives within 3 working days. More about the Supplement Check
What it is
A concentrate or powdered extract of Montmorency tart cherries, rich in anthocyanins (the red-purple plant pigments). Choose a licensed natural health product (with an NPN) in capsule form, or a food product.
How it acts
Its plant compounds (polyphenols) act as antioxidants and dampen inflammation. That is mechanism, not proof: in the trials it did not change creatine kinase, a blood marker of muscle damage. [1]
What it is used for, and what the evidence says
| Use | What the trials found | How sure we are |
|---|---|---|
| Strength recovery after strenuous exercise | In a pooled review of trials, strength came back faster with tart cherry than with placebo (standardised effect 0.78). [1] The trials were small and some had links to industry. | Low |
| Jump height after strenuous exercise | Jump height recovered better (standardised effect 0.82). [1] | Low |
| Muscle damage (creatine kinase in the blood) | No change. [1] | Low |
| Sleep | Also sold for sleep. Our review lists this use as weak and found no trial result to report. | Very low |
How sure we are: High means further research is very unlikely to change the answer; Moderate, it might; Low, it may well change; Very low, we are very unsure. These follow the GRADE method that guideline panels use.
Benefits
- Strength and jump height recover a little faster after very hard efforts, low certainty. [1]
- Muscle damage and sleep: no proven effect.
Risks and side effects
- Sugar. The concentrate carries a sugar load; capsules do not.
- Gut upset.
- Contaminated sport products. Untested “recovery” products can contain banned substances (see Canadians, below).
Interactions with medicines
None established in our review, and no change in how the liver clears medicines (no enzyme induction or inhibition) was reported. Tell us everything you take anyway: your check adds it all up.
Who should not take it
- Diabetes: use capsules, not concentrate (sugar).
- Drug-tested athletes: only a batch-tested product.
- Under 18: outside the Supplement Check, which is for adults.
Dose and timing
- Dose: 30 mL of concentrate twice a day for 4 to 5 days around the event (the hard session or competition).
- Form: concentrate, or capsules if you have diabetes or want to avoid the sugar.
- When: around very hard efforts only; ordinary training does not need it.
- Is it working: compare soreness and performance in repeat sessions with and without it.
What we know about Canadians
No Canadian data on tart cherry use in our review. About 27% of Canadians aged 15 and older played a sport regularly in 2016, and 14% of those competed. [2] The Canadian Centre for Ethics in Sport ran 3,423 tests under the Canadian Anti-Doping Program in 2024–25; fourteen rule violations were listed, mostly for anabolic agents and similar drugs. [3] Banned substances can turn up in contaminated sport products, which is why drug-tested athletes use only batch-tested products.
Most at risk (of a positive test from a supplement): university and national-team athletes, powerlifters and weightlifters, and anyone buying untested pre-workout, “recovery” or muscle products.
How sure are we: high. Official counts: Statistics Canada General Social Survey 2016 and Canadian Centre for Ethics in Sport 2024–25; nothing on tart cherry itself.
An honest comparison: recovery from hard training
Cost in Canadian dollars. Recovery trials are small and most cannot be blinded.
| Option | Effect | How sure we are | Cost a month (CAD) |
|---|---|---|---|
| Tart cherry concentrate | Strength recovery effect 0.78, jump height 0.82; no change in the muscle-damage marker [1] | Low | $30 to $50 |
| Sleep 7 to 9 hours, and protein after training | The foundation of every guideline; not measured directly as recovery | Low | $0 |
| Massage | The most effective option for muscle soreness and perceived fatigue [4] | Low | About $100 a session |
| Compression garments or cold-water immersion | Less perceived fatigue; [4] regular cold-water immersion after strength sessions blunted strength and muscle gains [5] | Low | $50 to $100 once |
| Ibuprofen or naproxen (over the counter) | Relieves soreness; high doses blunted muscle growth in young adults in one trial (not reviewed by us) | Low | About $5 |
Read honestly: tart cherry gives a small, uncertain help after very hard efforts. Sleep and protein come first, massage helps soreness more than any pill, and painkillers are not for routine use.
Our verdict
A personal choice. Tart cherry is reasonable for an athlete who wants a small edge after very hard sessions or competitions, taken for a few days around the event. It is not needed for ordinary training, and it does not replace sleep, protein and sensible training loads.
If you have diabetes, use capsules rather than concentrate. If you are tested for banned substances, use only a batch-tested product.
The trials are small, some are linked to industry and the certainty is low, but pooled trials showed faster strength recovery, the risks are small and no medicine interactions are established. At $30 to $50 a month it costs more than the lifestyle steps that matter most, and it helps less than they do, which is why it is optional rather than recommended. Dr. French approved this verdict with the 20 October 2026 evidence review.
