Are Cherries Good for Gout and Uric Acid?
Maybe, for attacks. Cherries are linked to fewer gout attacks, but the evidence that they lower uric acid is mixed, and no placebo-controlled trial has shown they prevent flares. They are a reasonable food to add, not a replacement for gout medicine.
The best-known study followed 633 people with gout and found that eating cherries in the previous 2 days was tied to about a third fewer attacks. That was an observational study, which shows a link, not proof. The randomized trials that came after it are small, and they disagree with each other on uric acid.
What the Data Show
Gout is a painful arthritis caused by too much uric acid in the blood. When the level is high enough, uric acid forms sharp crystals in a joint, often the big toe, and the immune system attacks them.
The main study is a case-crossover study of 633 people with gout. In this design, each person is compared with themselves: the 2 days before an attack against 2-day stretches with no attack. Cherry intake over a 2-day period was linked to a 35% lower risk of an attack compared with no cherries. Cherry extract showed a similar link, with about 45% lower risk. The link held in men and women, in people with and without obesity, and in people who drank alcohol or took diuretics (water pills).
Since then, the evidence has stayed thin. A systematic review of 6 studies found that people who regularly took cherry extract or juice reported fewer flares, but the studies were too different from each other to pool into one number.
The only trial of cherry extract against flares over many months was a pilot trial of 84 people with gout. One group took 3,600 mg of cherry extract a day, the other got help from a dietitian. After 9 months, the share of people in the cherry group with any flare fell from 98% to 56%. But the diet group improved too, from 98% to 65%, and there was no placebo group. The authors concluded that a large trial of cherry extract against a placebo is still needed.
Do Cherries Lower Uric Acid?
Sometimes, and only modestly. This is where the evidence splits.
In a placebo-controlled trial of 26 overweight or obese adults, drinking 8 ounces (240 mL) of tart cherry juice a day for 4 weeks lowered uric acid by 19.2%. These people did not have gout.
In people who do have gout, the result was different. A randomized trial of 50 people with gout gave either a placebo or one of four doses of tart cherry concentrate twice a day for 28 days. No dose changed uric acid, the amount of uric acid leaving in the urine, or the number of flares.
A 2026 meta-analysis of 4 randomized trials with 392 people pooled the tart cherry data and found a modest drop in uric acid, with results that varied a lot from trial to trial. The authors called the evidence limited in quantity and consistency.
So is the cherry cure a myth? Not entirely. The attack data are real, but the idea that cherries work by driving uric acid down has not held up well in people with gout.
How Do Cherries Help Gout?
There are two leading ideas, and neither is proven in people with gout.
More uric acid out through the kidneys. In a study of 10 healthy women, eating about 280 g of sweet Bing cherries raised the amount of uric acid in the urine, with a peak 3 hours later. Blood uric acid fell from 214 to 183 µmol/L by 5 hours, about 14% lower.
Less inflammation in the joint. Cherries are rich in anthocyanins, the red-purple pigments in the fruit. In a mouse model of gout, tart cherry juice concentrate cut the activity of NF-kB, a master switch for inflammation, by about half in the injected ankle, and fewer immune cells moved into the joint. That was in mice, not people.
The gout dose trial pointed in the same direction. Its authors wrote that if cherries do reduce flares over time, the effect is not likely to come from lowering uric acid. Calming inflammation is the more plausible path.
How Long Does It Take for Cherries to Help Gout?
It depends on what you measure. In the 10-woman study above, blood uric acid dropped within 5 hours of one bowl of cherries. But that study had no comparison group. When a later crossover trial in 12 healthy adults compared tart cherry juice with plain water, the juice made no difference. Uric acid naturally falls through the day, and that daily dip may explain much of the quick drop seen in earlier studies.
For attacks, the observational study looked at cherries eaten over the 2 days before a flare, and the pilot trial counted flares over 9 months. If cherries help, expect it to show up over weeks to months of regular intake, not overnight.
How Many Cherries Should You Eat a Day for Gout?
No study has found a best dose. The amounts tested include:
| Form | Amount tested | What happened |
|---|---|---|
| Fresh sweet cherries | About 280 g (two servings) once | Blood uric acid lower at 5 hours, no control group |
| Tart cherry juice | 8 oz (240 mL) a day for 4 weeks | Uric acid down 19.2% in overweight adults without gout |
| Tart cherry concentrate | 7.5 to 30 mL twice a day for 28 days | No change in uric acid or flares in people with gout |
| Cherry extract | 3,600 mg a day for 9 months | Fewer flares than at the start, but no placebo group |
Higher doses of concentrate did no better than lower ones. Fresh cherries and cherry extract both showed a similar link to fewer attacks in the 633-person study. Tart and sweet cherries have never been compared head to head for gout. The 280 g serving in the fresh-fruit study works out to roughly 2 cups. If you want to try cherries, a daily bowl of the fruit is the lowest-risk way to do it.
Can You Take Tart Cherry Extract With Allopurinol?
Nothing in the studies suggests a problem. In the 633-person study, periods when people ate cherries while taking allopurinol carried a 75% lower risk of attacks than periods with neither. In the dose trial, half the people were on allopurinol, and only one side effect out of 24 (high blood sugar) was judged possibly related to the cherry concentrate.
A randomized trial of 282 men with gout starting febuxostat, another uric acid drug, added a tart cherry and citrate mixture to one group. Uric acid fell about the same in all three groups, and side effects were similar. The cherry group had lower CRP, a blood marker of inflammation, at 12 weeks, and less protein leaking into the urine.
No formal drug-interaction study of cherries and allopurinol exists. And no study has tested cherries as a replacement for allopurinol. The drug lowers uric acid reliably. Cherries do not.
Are Cherry Juice and Concentrate Safe for Gout?
Whole cherries are a safe food. Juice and concentrate need more thought.
Sugar. Fruit juice is a concentrated source of fructose, a sugar that raises uric acid. In a 22-year study of 78,906 women, drinking one glass of orange juice a day was linked to 41% higher risk of developing gout, and two or more a day to more than double the risk. In absolute terms, that was 14 and 47 extra cases per 100,000 women per year. That study did not measure cherry juice, but sweetened cherry juice carries the same sugar. Choose unsweetened juice, or the whole fruit.
Kidneys. In a case report, a man with diabetic kidney disease developed acute kidney injury after drinking black cherry concentrate to treat a gout flare, and his kidneys recovered after he stopped. The authors noted it was the second such case. If you have chronic kidney disease, check with your doctor before using concentrates.
Dr. Kumar’s Take
Cherries have a better case than most gout folk remedies. A large study tied them to fewer attacks, and the pigments in them calm inflammation in lab models. But the trials that should have confirmed this are small, short, or missing a placebo, and the best trial in people with gout found no change in uric acid at any dose.
I see cherries as a food worth eating, not a treatment. A bowl of fresh cherries fits a gout-friendly diet. A bottle of sweetened juice may work against you. And anyone with frequent attacks or tophi (chalky lumps of uric acid under the skin) needs a uric acid target and a plan to reach it, which cherries will not deliver.
Practical Takeaways
- Eat the fruit. A daily bowl of fresh or frozen cherries, up to about 2 cups, matches the amount studied.
- Pick unsweetened juice if you prefer juice, and keep it to about 8 ounces a day.
- Extract is an option if you dislike the taste; 3,600 mg a day is what the longest trial used.
- Keep taking allopurinol or other uric acid medicine. Cherries are an add-on, not a swap.
- Be careful with concentrates if you have kidney disease.
- Watch other fructose sources, like soda and orange juice, which track with more gout.

FAQs
Are cherries good for gout?
They may help. In a study of 633 people with gout, eating cherries over 2 days was linked to 35% lower risk of an attack. Trials since then are small and mixed, so cherries are best used alongside gout treatment, not instead of it.
Do tart cherries work better than sweet cherries for gout?
No study has compared them directly. The quick uric acid study used sweet Bing cherries, and most juice and concentrate trials used tart cherries. Either is a reasonable choice as food.
Can cherries stop a gout flare that has already started?
No study has tested that. The research looked at preventing attacks, not treating one in progress. A flare that has started needs the anti-inflammatory treatment your doctor recommends.
Are dried cherries good for gout?
Dried cherries have not been studied for gout. They pack more sugar per handful than fresh cherries, so fresh or frozen is the better pick.
Can I take tart cherry extract with allopurinol?
The studies that included people on allopurinol found no added safety problem, and the combination was linked to the lowest attack risk. No formal interaction study exists, so mention it to your doctor or pharmacist.
Bottom Line
Cherries are linked to fewer gout attacks, but the claim that they lower uric acid is shaky, and the best trial in people with gout found no effect on it. Eat the fruit, skip sweetened juice, use caution with concentrates if your kidneys are weak, and keep taking the medicine that actually lowers uric acid.
