The most evidence-backed supplements for gout are tart cherry extract (which lowers uric acid and reduces flare risk by 35-45%), vitamin C (500mg daily shown to reduce uric acid by 0.35 mg/dL), and quercetin (500mg daily inhibits xanthine oxidase activity).

Gout is an inflammatory arthritis caused by the deposition of monosodium urate crystals in joints, most commonly the big toe. It affects approximately 9.2 million adults in the United States and is strongly associated with elevated serum uric acid levels. Several supplements have demonstrated urate-lowering or anti-inflammatory properties in clinical studies.
Gout is caused by the deposition of monosodium urate (MSU) crystals in joints, triggered when serum uric acid exceeds its saturation point (approximately 6.8 mg/dL). Uric acid is the end product of purine metabolism, produced by the enzyme xanthine oxidase. When serum levels remain elevated, MSU crystals form in the synovial fluid and surrounding tissues, activating the NLRP3 inflammasome in macrophages and triggering an intense inflammatory cascade mediated by IL-1-beta, neutrophil infiltration, and prostaglandin release — producing the characteristic excruciating pain and swelling of acute gout. Chronic hyperuricemia leads to recurrent flares, tophi formation, and joint destruction. Pharmaceutical management uses allopurinol or febuxostat (xanthine oxidase inhibitors) for urate lowering and colchicine or NSAIDs for acute flares. Supplements that lower uric acid production, increase its excretion, or modulate the inflammatory response have some supporting evidence, though none replace pharmacotherapy for confirmed gout.
Vitamin C has the best evidence for modest uric acid reduction. Juraschek et al. (2011) conducted a meta-analysis of 13 RCTs with 556 participants and found that vitamin C supplementation (median dose 500 mg/day) reduced serum uric acid by 0.35 mg/dL on average. The mechanism involves increased renal urate excretion through competition with uric acid for reabsorption at the URAT1 transporter in the proximal tubule. A large prospective cohort by Choi et al. (2009) in the Archives of Internal Medicine found that men taking vitamin C supplements had a 44% lower risk of incident gout. However, the magnitude of uric acid reduction is modest — inadequate for most patients with established gout who need to reach the 6 mg/dL target. Tart cherry (Prunus cerasus) contains anthocyanins that inhibit xanthine oxidase activity and reduce inflammatory markers. Zhang et al. (2012) published a landmark study in Arthritis & Rheumatism following 633 gout patients and found that cherry intake (fresh or extract) over a 2-day period reduced gout flare risk by 35%, and combining cherries with allopurinol reduced risk by 75%. A small RCT by Schlesinger et al. (2012) found tart cherry juice concentrate reduced serum urate and CRP levels. Quercetin, a flavonoid found in onions and apples, inhibits xanthine oxidase in vitro. Shi and Williamson (2016) reviewed the evidence and found that quercetin at 500 mg daily reduced serum uric acid in hyperuricemic subjects, though clinical trial data in diagnosed gout patients remains limited. Omega-3 fatty acids may help with the inflammatory component — a small pilot by Tate et al. (2012) found that 1.5 g EPA+DHA daily reduced gout flare frequency, but this has not been replicated in large RCTs.
For vitamin C, standard ascorbic acid at 500–1,000 mg daily is sufficient — no need for expensive buffered or liposomal forms for this indication. Higher doses do not proportionally increase uric acid lowering and may increase kidney stone risk in susceptible individuals. For tart cherry, look for concentrated extracts providing the equivalent of 45–60 cherries per serving (typically 500 mg of concentrated extract or 8–12 oz of tart cherry juice concentrate). CherryPURE and CherryFlex are standardized extracts used in research. Montmorency tart cherry is the most studied variety. For quercetin, choose products providing 500 mg of quercetin dihydrate or quercetin phytosome (Quercefit) — the phytosome form has approximately 20x better bioavailability than standard quercetin. Third-party testing is important to verify anthocyanin content in cherry products, as concentrations vary widely between brands.
Apple cider vinegar is one of the most popular folk remedies for gout, but there is zero clinical trial evidence supporting its use for uric acid reduction or gout flare prevention. The claim that it "alkalizes the body" to dissolve urate crystals misunderstands both acid-base physiology and urate chemistry. Celery seed extract is another commonly promoted supplement with no RCT evidence for gout. Bromelain (pineapple enzyme) has general anti-inflammatory properties but has not been tested in gout-specific trials. Baking soda (sodium bicarbonate), while it does alkalinize urine and can theoretically increase urate excretion, provides excessive sodium, risks metabolic alkalosis, and has no controlled evidence for gout management. High-dose vitamin C (over 2,000 mg/day) offers no additional uric acid benefit over 500 mg and increases oxalate kidney stone risk. Activated charcoal, sometimes claimed to absorb uric acid, has no supporting evidence.
For adjunctive gout management alongside medical therapy: vitamin C 500 mg daily (preferably with a meal), tart cherry extract 500 mg twice daily or 8 oz tart cherry juice concentrate daily, and quercetin 500 mg twice daily. This combination targets three mechanisms: increased renal urate excretion (vitamin C), xanthine oxidase inhibition (cherry anthocyanins and quercetin), and anti-inflammatory modulation. These supplements are adjuncts to — not replacements for — allopurinol or febuxostat in patients with serum urate above 6 mg/dL or recurrent flares. Hydration is critical: aim for 2–3 liters of water daily to support uric acid excretion. Monitor serum uric acid quarterly. No existing stack page directly applies, but /stacks/immune-resilience shares anti-inflammatory principles.
Supplements may lower uric acid slightly; they do not replace urate-lowering medication when flares recur. Seek urgent care for any joint that is hot, swollen, and painful and coincides with fever or chills (septic arthritis must be ruled out — a true emergency), for suspected gout in a prosthetic joint, or for rapid onset of severe pain in the great toe with systemic symptoms. Book same-week rheumatology or primary-care evaluation for two or more flares per year, a single severe attack lasting more than a week, any tophi (hardened uric-acid deposits in ears, fingers, or tendons), a history of kidney stones, or chronic kidney disease alongside elevated uric acid. First-line care is NSAIDs or colchicine for acute flares and allopurinol or febuxostat for long-term urate lowering; tart cherry, vitamin C, and low-purine diet choices are evidence-backed adjuncts.

Yes. A prospective study of 633 gout patients published in Arthritis & Rheumatism found that cherry intake (whole fruit or extract) over a two-day period was associated with a 35% lower risk of gout attacks [1]. Tart cherry contains anthocyanins that inhibit inflammatory pathways and may modestly reduce uric acid levels.
Evidence:Observational (2012) · n=633 · moderate confidence[#1]. See full reference list below.A meta-analysis of 13 randomized controlled trials found that vitamin C supplementation (median dose 500mg/day) significantly reduced serum uric acid by 0.35 mg/dL. Vitamin C enhances renal uric acid excretion. While helpful for mild hyperuricemia, it should not replace urate-lowering therapy prescribed for diagnosed gout.
Omega-3 fatty acids (1-2g EPA+DHA) and curcumin (500mg twice daily) both reduce pro-inflammatory cytokines involved in gout flares. Tart cherry extract also provides acute anti-inflammatory benefits. These can complement, but should not replace, physician-directed flare management.
Quercetin inhibits xanthine oxidase, the same enzyme targeted by the prescription drug allopurinol, though with weaker potency. A small RCT in hyperuricemic men showed 500mg daily reduced uric acid levels. Evidence is still emerging, but quercetin may be a useful adjunct for mild hyperuricemia.
Tart cherry is one of the few foods clinically proven to improve sleep. An RCT found tart cherry juice increased melatonin levels, added 25 minutes of sleep time, and improved sleep efficiency by 5-6%. It provides natural melatonin plus anti-inflammatory proanthocyanidins that reduce sleep-disrupting inflammation.
