Based on PubMed | Does drinking green tea reduce uric acid levels and help prevent gout flare-ups?

Green tea is unlikely to meaningfully lower uric acid on its own or reliably prevent gout flares. Evidence in people is limited and mixed, and current gout guidance emphasizes proven medications and broader diet/lifestyle changes rather than green tea as a primary strategy. At best, green tea or its extracts may have a small, short‑term effect on uric acid that is not strong enough to replace standard therapy. ^{[1] [2]}

What the research shows

• Human data are sparse. In a small randomized study of healthy adults, two weeks of green tea extract led to a modest, statistically non‑significant drop in serum uric acid (largest average decrease ~3.5%), while uric acid clearance through the kidneys actually decreased at lower doses. The effect was short‑term and did not establish benefit for people with high uric acid or gout. ^[3]
• Laboratory and animal work suggests green tea polyphenols (notably EGCG) can inhibit xanthine oxidase, an enzyme that helps produce uric acid, but these models do not guarantee real‑world benefit in humans with gout. Translating these findings to clinical prevention of flares remains unproven. ^{[4] [5]}

What guidelines and experts prioritize

• Diet can help reduce the number and severity of gout attacks, but diet alone usually does not lower uric acid enough to treat gout without medication when gout is established. ^{[1] [2]}
• Recommended diet/lifestyle measures focus on limiting high‑purine foods (especially certain meats and seafood), curbing alcohol (particularly beer and spirits), maintaining a healthy weight, limiting fructose‑sweetened drinks, and staying physically active. These steps have broader and better‑supported benefits than adding green tea. ^[6]

Potential pros and cons of green tea

• Possible benefits: Green tea is a low‑calorie beverage and may offer antioxidant effects; some observational work links coffee (not green tea) with lower gout risk, but there is not comparable, consistent evidence for green tea itself. ^[7]
• Possible downsides: Concentrated green tea extracts can cause gastrointestinal upset and have variable interactions with certain drugs. While there are no well‑documented, clinically significant interactions with common gout medicines such as allopurinol or febuxostat, green tea products can alter exposure to other medications in some settings and should be used cautiously in supplement form. ^{[3] [8]}

Practical takeaways

• If you enjoy green tea, it can be part of a gout‑friendly diet as a low‑purine, low‑sugar drink. However, it should be considered an optional beverage choice not a treatment for high uric acid or a proven way to prevent flares. ^{[1] [2]}
• For preventing gout flares effectively, the most reliable strategies are:
  • Urate‑lowering therapy prescribed by a clinician when indicated (for example, allopurinol or febuxostat). ^{[9] [10]}
  • Diet and lifestyle changes: limit purine‑rich foods and alcohol, manage weight, and exercise regularly. ^{[11] [1]}
• If you are considering green tea extract capsules, discuss with your clinician, especially if you have liver disease, take multiple medications, or are on cancer therapies, because concentrated extracts may carry more risk than brewed tea. ^[8]

Bottom line

Green tea is not a proven therapy for lowering uric acid or preventing gout attacks and, at most, may have a small, short‑term effect that is unlikely to be clinically meaningful. Use green tea as a healthy beverage if you like the taste, but rely on established medications and guideline‑supported diet/lifestyle measures to control uric acid and reduce flares. ^{[3] [1] [6] [10]}

Quick reference table

Topic	What we know	Clinical impact
Green tea extract in humans	Small, non‑significant uric acid reduction over 2 weeks; decreased uric acid clearance at some doses; short‑term findings in healthy adults	Insufficient evidence to recommend for gout prevention or treatment [3]
Mechanism (preclinical)	EGCG and other flavonoids can inhibit xanthine oxidase in lab/animal studies	Promising in theory, but not confirmed to prevent flares in people [4] [5]
Diet role in gout	Diet can help reduce attacks but usually cannot normalize uric acid without medicine in established gout	Adjunct to medication, not a standalone cure [1] [2]
First‑line prevention	Urate‑lowering therapy, alcohol/purine reduction, weight and activity goals	Best‑supported strategies for flare prevention [11] [10]
