What dose of tart cherry juice helps with gout?
The strongest gout evidence used a Montmorency tart cherry supplement combined with a citrate mixture in patients already on standard medication -- specifically "cherry juice," broadly, hasn't been tested to the same standard.
The short answer
A large randomized controlled trial testing a tart cherry supplement combined with citrate found measurable benefits for urine pH and serum uric acid in gout patients already on standard medication (febuxostat) with acidic urine. The key detail is specificity: this evidence applies to the Montmorency tart cherry variety combined with citrate, not "cherry juice" broadly, which is not necessarily the same product as what generic commercial juice delivers. It's studied as an adjunct alongside standard gout medication, not a replacement, and cherry products can be high in natural or added sugar, worth checking on the label for anyone monitoring blood sugar.
