Gout — uric acid lowering and acute attack support

Updated 2026-05-02 · Reviewed by SupplementScore editors · No sponsorships

Gout is the most common inflammatory arthritis in adults, and uric-acid-lowering supplements are a popular search query because the prescription urate-lowering medications (allopurinol, febuxostat) are sometimes poorly tolerated and the dietary advice can feel restrictive. The supplement evidence is narrower than the marketing suggests but real for two specific compounds.

Read this first. Established gout — particularly recurrent attacks, joint damage on imaging, or tophi — needs prescription urate-lowering therapy. Supplements alone do not get most patients below the 6 mg/dL serum urate target that prevents attacks and joint destruction. This guide is for prevention in hyperuricaemia without established disease, for adjunctive support alongside prescription therapy, and for acute-attack symptom support — not as a substitute for proper management of established gout.

Supplements with the strongest evidence

Tier 2 evidence · Acute attack frequency reduction

Tart cherry (Montmorency) extract or juice

240–480 mL tart cherry juice daily, or 1–2 g concentrated tart cherry extract

The most consistent supplement signal in gout is for tart cherry, with multiple cohort studies and small RCTs showing reduced gout attack frequency in patients who consume tart cherry regularly. Mechanism likely involves both modest urate-lowering and direct anti-inflammatory effect. Effect size is meaningful in cohort data — roughly 35% lower attack rate over 48-hour windows compared with non-consumers — but trial-grade evidence remains modest. Sweet cherries probably do not have the same effect; tart Montmorency is the variety in the trial literature.

Tier 2 evidence · Modest urate-lowering

Vitamin C

500 mg/day

Multiple meta-analyses confirm vitamin C at 500 mg/day modestly lowers serum uric acid (typically by 0.3 to 0.5 mg/dL), via increased renal urate excretion. Effect size is too small to be primary therapy for established gout but reasonable as an adjunct, particularly in hyperuricaemic patients without established disease. The CARES trial of pure vitamin C in gout patients was modestly positive on serum urate. Generally safe; high doses can occasionally precipitate calcium oxalate kidney stones in susceptible individuals.

Tier 3 evidence · Theoretical mechanism · Anti-inflammatory

Omega-3 fatty acids (EPA + DHA)

1–2 g/day combined EPA + DHA

Anti-inflammatory effects via shifted eicosanoid balance; reasonable mechanism for symptom-burden reduction in gout. Direct gout RCT evidence is limited. Reasonable to include for the broader cardiovascular benefit (gout is associated with elevated cardiovascular risk independently). Mind the high-dose AFib paradox at chronic doses above 1 g/day.

The dietary layer that matters more than supplements

Several dietary inputs have larger effect sizes on uric acid than any of the above supplements:

Fructose-sweetened beverages — high-fructose corn syrup and sucrose-sweetened drinks raise serum urate via the fructose metabolism pathway. Reducing or eliminating sugar-sweetened beverages produces 0.5+ mg/dL urate reductions in trials.
Beer and spirits — both raise urate (beer also via its purine content; spirits via reduced renal excretion). Wine has a smaller effect.
Organ meats, anchovies, sardines — concentrated purine sources; useful to limit during active flare and tophus burden management. Routine red meat at moderate amounts is less of an issue than the older guidance suggested.
Dairy (low-fat) — independently associated with lower gout incidence in cohort studies; the casein and whey have urate-lowering effects.
Coffee (3+ cups/day) — associated with lower gout incidence in cohort data; useful information rather than a prescription.
Hydration — useful both for renal urate excretion and for prevention of crystal formation.

Supplements that may worsen gout

Niacin (high-dose, immediate-release) — competes with urate at renal tubules, raising serum urate. Long-known interaction. The flush-free hexanicotinate form does not have the same effect.
Vitamin A (very high doses) — case reports of urate elevation at very high supplemental doses.
Creatine (during loading phase) — modest, transient urate elevation in some users; usually clinically irrelevant outside established gout.
Brewer's yeast and similar yeast-derived "B-vitamin complexes" — high purine content can precipitate flares.
Spirulina and chlorella in large amounts — non-trivial purine content.

Acute attack support

An acute gout attack is unfortunately not a supplement-tier conversation. Standard care is NSAIDs (where not contraindicated by kidney or cardiovascular risk), colchicine, or short-course oral or intra-articular corticosteroids — all of which work much faster and more reliably than any supplement. Tart cherry juice during an active attack is a reasonable adjunct but should not delay starting evidence-based pharmacological treatment. Do not start or stop urate-lowering therapy during an acute attack.

What to skip

"Uric acid cleanse" multi-ingredient products — typically combine tart cherry, celery seed, hibiscus, and other low-evidence ingredients in proprietary blends.
Apple-cider vinegar protocols — no urate-lowering evidence; theoretical mechanism does not hold up.
Celery seed extract — popular in folk traditions, very limited human evidence.
Bromelain alone for attacks — anti-inflammatory effect too modest to substitute for evidence-based treatment.

What to track

Serum uric acid (target < 6 mg/dL for established gout, < 5 mg/dL if tophi present), gout attack frequency, and whether you can tolerate the prescription urate-lowering therapy if indicated. Repeat serum urate every 3 to 6 months on therapy.

Practical quick-start. For hyperuricaemia or recurrent gout patients on prescription urate-lowering therapy: tart cherry concentrate (1 g daily, or 240 mL juice) + vitamin C 500 mg daily, plus the dietary layer (eliminate sugar-sweetened beverages, limit beer and spirits, prioritise low-fat dairy and adequate hydration). Reassess serum urate at 3 months. Supplements are an adjunct to prescription therapy, not a replacement for it in established disease.
