Gout flares are painful enough that anyone who’s had one is usually willing to try almost anything to avoid the next. Tart cherry has become one of the most searched natural approaches, often mentioned alongside — or instead of — prescription urate-lowering medication.
The research on tart cherry and gout is genuinely more substantial than for most “natural remedy” claims, but it’s also more mixed than the enthusiastic anecdotes suggest. Here’s what the actual clinical evidence says, and where it falls short.
The Uric Acid Connection
Gout develops when uric acid builds up in the blood and forms sharp crystals in joints, most classically in the big toe, triggering sudden, intense inflammation and pain.
Uric acid is a natural byproduct of purine metabolism, and levels can rise due to diet, genetics, kidney function, certain medications, or a combination of these. Managing gout typically involves both reducing flare frequency and, for many patients, long-term urate-lowering therapy prescribed by a doctor.
Tart cherry’s anthocyanins are thought to have two potentially relevant effects: a mild influence on uric acid excretion, and a more consistently observed anti-inflammatory effect that could theoretically reduce flare severity even without changing uric acid levels much.
What the Research Shows
An early systematic review of six studies found a general association between cherry intake and reduced gout attack frequency, along with a correlation between tart cherry juice consumption and lower serum uric acid — though the review noted the included studies varied in quality and design.
A more recent randomized controlled trial compared a tart cherry–citrate mixture against a standard citrate mixture and sodium bicarbonate in gout patients starting urate-lowering therapy. Uric acid levels declined similarly across all three groups, but the tart cherry group showed a greater drop in CRP, a marker of inflammation, along with fewer gout flares compared to the sodium bicarbonate group specifically.
Other trials have been less encouraging. A randomized trial published in Rheumatology found that tart cherry concentrate had no measurable effect on serum urate concentration or urinary urate excretion, regardless of dose, when added alongside allopurinol therapy. A more recent randomized crossover trial similarly found no acute effect of a single serving of tart cherry juice on uric acid levels.
Taken together, the evidence suggests tart cherry’s benefit — where it exists — is more likely tied to reducing inflammation and possibly flare frequency, rather than reliably lowering uric acid itself.
Why This Distinction Matters
Someone relying on tart cherry expecting it to lower their uric acid numbers on a lab test may be disappointed, since several controlled trials found no such effect.
Someone using it as a complementary approach to reduce inflammation and possibly ease flare severity — alongside, not instead of, prescribed urate-lowering medication — has more consistent (though still not definitive) research behind that specific goal.
This is an important distinction for a condition like gout, where uncontrolled uric acid can cause progressive joint damage over time regardless of how someone feels day to day.
Dosage Used in Gout-Related Research
Studies have used a range of approaches, from roughly one tablespoon of concentrated tart cherry extract twice daily to 8 ounces of diluted tart cherry juice concentrate consumed daily over several weeks.
Trial durations have ranged from a few weeks to four months, and most researchers note that any effect on flare frequency appears to require consistent use over time rather than occasional consumption during a flare itself.
What Tart Cherry Is Not a Substitute For
Tart cherry has not been shown in rigorous trials to reliably lower uric acid the way prescription urate-lowering medications like allopurinol or febuxostat do, and it is not a treatment for gout.
Anyone diagnosed with gout, or with uric acid levels in a range their doctor considers a concern, should continue prescribed urate-lowering therapy and use tart cherry, if at all, as a complementary addition rather than a replacement — and only after discussing it with their doctor, particularly if already on gout medication.
Safety Considerations
Tart cherry juice’s natural sugar content is worth considering for anyone with gout who also has metabolic syndrome or diabetes, which frequently co-occur with hyperuricemia.
There’s no strong evidence that tart cherry interacts negatively with common urate-lowering medications like allopurinol or febuxostat, but anyone starting or adjusting gout medication should mention any supplements, including tart cherry, to their prescribing doctor.
The Bottom Line
Tart cherry has a more substantial research base for gout than most natural remedies, but the picture is mixed: some trials show reduced inflammation and fewer flares, while others show no measurable effect on uric acid itself.
It’s reasonable to view tart cherry as a possible complementary addition for someone already under medical care for gout, not as a standalone treatment or a substitute for prescribed urate-lowering therapy.

FAQs
Does tart cherry juice lower uric acid?
The evidence is mixed. Some studies show a modest reduction in uric acid with regular use, while other well-controlled trials found no significant effect, even at higher doses.
Can tart cherry replace my gout medication?
No. Tart cherry has not been shown to reliably lower uric acid the way prescription urate-lowering medications do, and it should not replace medication prescribed by a doctor.
How long does it take for tart cherry to help with gout?
Studies showing a possible benefit generally used several weeks to a few months of consistent daily use, not occasional consumption during a flare.
Is tart cherry safe to take with allopurinol or febuxostat?
Current research hasn’t identified a negative interaction, and one trial specifically studied tart cherry alongside allopurinol without safety concerns. Still, anyone on gout medication should tell their doctor about any supplements they’re taking.
Can tart cherry help during an active gout flare?
Most research has looked at regular, ongoing use for prevention rather than treatment of an active flare. Anyone experiencing a gout flare should follow their doctor’s guidance for flare management rather than relying on tart cherry alone.
Is tart cherry juice or capsules better for gout?
Most gout-related research has used juice or concentrated extract rather than standard capsules, so there’s less direct evidence for capsule dosing. Anyone choosing capsules for this purpose should look for products with a comparable anthocyanin content to what’s been studied.
