Supplements for Gout.
Some supplements have been studied for their potential effect on uric acid or gout, but the evidence varies considerably. This guide separates the more promising options from those with limited evidence and explains what to consider before taking them.
The Quick Answer
There's currently no supplement that should be regarded as a replacement for proven gout treatment, including prescribed urate-lowering medication such as allopurinol when your doctor has recommended it. No pill, powder or juice has been shown to control gout as reliably as appropriate medical care.
That said, a small number of supplements and dietary compounds — most notably vitamin C and tart cherry extract — have been studied for a modest effect on uric acid. The evidence for most others is limited, mixed, or simply too early to draw firm conclusions from, and a few need genuine caution.
The Basics
What the Evidence Actually Shows
It's easy to see why supplements are appealing. Gout is painful, uric acid is a specific, measurable number, and the idea of a pill or juice that helps clear it feels like a comforting shortcut. The reality is more complicated. Some nutrients and plant compounds do appear to influence uric acid slightly under controlled study conditions, but "influences uric acid in a trial" is a long way from "treats gout" in everyday life.
Evidence in this area comes in different strengths. Some findings come from randomised controlled trials, where a supplement is compared with a placebo under controlled conditions — this is generally the strongest type of evidence. Others come from observational studies, which can show a pattern (for example, people who eat more cherries tend to report fewer flares) without proving that the cherries caused the difference. Throughout this guide, we've tried to be clear about which kind of evidence sits behind each claim.
Even where a supplement modestly lowers uric acid in a trial, that isn't the same as proving it prevents flares or joint damage over years — the outcome that actually matters clinically.
This page also can't cover every product marketed for gout — the supplement market moves quickly, and new blends and "gout formulas" appear regularly, often with far more confident marketing than evidence behind them. If a product isn't mentioned here, that isn't a judgement on it; it usually just means the evidence is too thin, too new, or too inconsistent to summarise responsibly.
The Candidates
Supplements With the Most Relevant Evidence
A small number of supplements have been studied specifically in relation to uric acid or gout. None come close to the effect of urate-lowering medication, but here's what the research suggests about the options most commonly discussed.
Vitamin C
Vitamin C is the most studied supplement in this area. A meta-analysis of randomised trials found that around 500mg a day modestly reduced serum uric acid — by roughly 0.35mg/dL on average — over periods of a few weeks to months. A large prospective study also found that men with the highest vitamin C intake had a notably lower long-term risk of developing gout than those with the lowest intake.
The most direct evidence comes from the Physicians' Health Study II, a randomised trial in which men took 500mg of vitamin C daily for several years. It found a modest 12% reduction in the risk of developing gout — a real but small effect that the study's own authors said wasn't yet enough to justify a general recommendation to supplement. The effect was weaker in men who already had gout, and appeared less pronounced in men with a higher body weight.
In short, vitamin C looks more promising than most other supplements on this list, but a modest reduction in risk within a trial is different from a treatment. NHS guidance suggests asking your GP about vitamin C rather than starting it as a substitute for other care.
Tart Cherry and Cherry Extract
Cherries — fresh, juiced, or as a concentrated extract — are probably the most talked-about food-based option for gout. The best-known study followed gout patients for a year and found that eating cherries in the two days around a flare was associated with a 35% lower risk of an attack, rising further in people who also took allopurinol. This was an observational study based on self-reported intake, so it shows an association rather than proof that cherries caused the reduction, and the study's own editorial called for randomised trials to confirm it.
A more recent trial gave gout patients a concentrated tart cherry and citrate mixture alongside their usual urate-lowering medication. Uric acid fell similarly across all groups studied, but the cherry-citrate group had somewhat fewer flares and lower inflammation markers than a comparison group over 12 weeks. It was a single-site, open-label study in men only, so it adds a useful data point without settling the question.
Overall, cherries have some of the more encouraging evidence of any food or supplement covered here, particularly as an addition to — rather than a replacement for — standard treatment. A systematic review of the available studies described the evidence as promising but not yet conclusive enough to recommend a specific dose or preparation.
Other Potentially Relevant Supplements
A few other supplements are commonly discussed in gout communities. The evidence behind them is considerably thinner than for vitamin C or cherries, so we've kept these summaries brief and cautious.
Quercetin
Quercetin is a plant compound found in onions, apples and capers. One small randomised trial in 22 healthy men with mildly raised uric acid found that 500mg a day lowered plasma uric acid by around 8% over four weeks. The study didn't include anyone with actual gout, was small, and looked only at men — best described as an early, interesting signal rather than evidence that quercetin helps manage gout.
Curcumin and Turmeric
Turmeric's active compound, curcumin, has anti-inflammatory properties in laboratory studies, and a small number of human trials have looked at its effect on uric acid, with mixed results. A 2020 review of the research concluded that curcumin's effect on serum uric acid "remains unknown" — not because it clearly doesn't work, but because the studies so far are too few, small or inconsistent to say either way. Turmeric can also interact with blood-thinning medication and isn't advisable in large amounts for people prone to kidney stones.
Omega-3 / Fish Oil
This is a good example of how "food" and "supplement" evidence can pull in different directions. A large observational study found that eating oily fish two or more times a week was linked to a 26% lower risk of a gout flare — but taking a fish oil supplement in the same study showed no such benefit. A small pilot trial giving gout patients 6.2g of fish oil daily for six months found no significant difference in uric acid compared with no supplementation, although participants who achieved higher omega-3 levels in their blood did report fewer flares. Larger trials are still needed before any firmer conclusion is possible.
Magnesium
Some population studies have linked lower magnesium levels with a higher likelihood of gout, but this kind of cross-sectional data can't show whether low magnesium contributes to gout, results from it, or simply reflects a wider pattern of diet and health. There isn't currently good trial evidence that magnesium supplements lower uric acid or reduce flares in people with gout.
At A Glance
Evidence Comparison
A side-by-side summary of the supplements covered on this page. This simplifies more nuanced research — the sections above give the fuller picture.
| Supplement | Why people take it | Evidence for gout / uric acid | Important considerations |
|---|---|---|---|
| Vitamin C | Antioxidant; studied for uric acid excretion | More promising — modestly lowers uric acid in trials; one large RCT found a modest reduction in gout risk | Generally well tolerated at typical doses; very high doses linked to kidney stone risk in susceptible people |
| Tart Cherry / Extract | Anthocyanins thought to have anti-inflammatory effects | More promising — mostly observational, with early supportive trial data | No agreed effective dose; juice and whole fruit also add natural sugars |
| Quercetin | Plant antioxidant found in onions & apples | Insufficient — one small, short trial in healthy men without gout | Not studied in people with gout; long-term safety at supplement doses unclear |
| Curcumin / Turmeric | Anti-inflammatory plant compound | Insufficient — effect on uric acid described as "remains unknown" | May interact with blood thinners; caution with a history of kidney stones |
| Omega-3 / Fish Oil | Anti-inflammatory fats | Mixed — dietary fish linked to benefit; supplement trials haven't confirmed it | Oily fish itself is a reasonable dietary choice; the supplement form is unproven |
| Magnesium | General mineral; muscle & nerve function | Insufficient — only correlational data available | No trial evidence supports supplementing specifically for gout |
| High-Dose Niacin (B3) | Sometimes taken for cholesterol | Not supportive — high doses can raise uric acid | Discuss with a GP or pharmacist first, especially if you have gout |
Use Caution
Supplements and Vitamins to Approach With Caution
High-dose niacin (vitamin B3) — sometimes taken for cholesterol management — can raise uric acid levels and increase the risk of gout. Mayo Clinic guidance notes that niacin should be used with care in people who have gout, and that it may also interact with allopurinol and increase bleeding risk when combined with blood-thinning medication. This doesn't apply to the small amount of niacin found naturally in food, which isn't a concern.
A useful general rule is that ordinary dietary intake of a nutrient is very rarely a problem, while concentrated, high-dose supplementation is where most of the genuine caution belongs. Beyond niacin specifically, be wary of any product marketed with claims like "flushes uric acid", "dissolves crystals" or "cures gout permanently" — these are marketing claims rather than descriptions backed by clinical evidence, and no supplement has been shown to dissolve existing urate crystals.
If you have kidney disease or reduced kidney function, take anticoagulants (blood thinners) or other prescription medication, or are considering a high-dose supplement of any kind, speak to your GP or pharmacist first. The kidneys play a central role in clearing both uric acid and many supplement ingredients, so this is a group for whom an individual check-in matters more than general guidance like this page can offer.
The Direct Answer
Can Supplements Lower Uric Acid?
A few supplements — vitamin C being the clearest example — can produce small, measurable reductions in uric acid under study conditions. But a small reduction in a trial needs to be seen against the much bigger picture of what actually matters clinically.
For people who need urate-lowering treatment, doctors generally aim for a specific uric acid target (often below 360 micromol/L, or lower for those with tophi or more severe disease) to allow existing crystals to dissolve and prevent new flares. Medication such as allopurinol can reliably bring most people to that target and keep them there. No supplement studied to date has been shown to reliably achieve or maintain a clinical target the way medication can.
- So, can supplements lower uric acid? A little, in some cases, under some conditions — but not enough, on their own, to replace treatment for anyone who needs it.
An Important Distinction
Supplements vs Gout Medication
It's worth being direct about this: supplements and prescribed gout medication are not interchangeable, and nothing on this page is suggesting otherwise. Medicines such as allopurinol and febuxostat work by directly reducing how much uric acid the body produces, and have decades of trial evidence behind their ability to lower uric acid reliably, help existing crystals dissolve over time, and reduce how often flares happen. No supplement discussed here has evidence anywhere near this strength.
Stopping or reducing prescribed urate-lowering medication in favour of a supplement — even one with reasonably good evidence, like vitamin C — risks allowing uric acid to climb back up, which can trigger flares and, over time, contribute to joint damage.
If you're currently taking urate-lowering medication, please don't stop, skip or reduce it without talking to your doctor first, even if you feel well — feeling well is often a sign the medication is working, not a sign it's no longer needed. If you're interested in adding a supplement alongside your treatment, that's a reasonable conversation to have with your GP or pharmacist, who can check for interactions and confirm it's appropriate for you.
Practical Guidance
How to Choose a Supplement Safely
If you and your GP or pharmacist decide a supplement is worth trying alongside your usual care, a few practical habits make it easier to do safely — and avoid wasting money.
- Check the ingredients list, not just the front of the pack — "gout support" blends often combine several ingredients at low, unproven doses rather than one at an effective dose.
- Avoid unnecessarily high doses. More isn't automatically better, and higher doses generally carry more potential for side effects or interactions.
- Watch for duplicate ingredients across different products — it's easy to unintentionally double up on the same vitamin from a multivitamin and a separate supplement.
- Ask your GP or pharmacist to check for interactions, especially if you take anticoagulants, allopurinol, or medication for other conditions.
- Be sceptical of products that promise to "cure gout", "flush uric acid" or guarantee results — responsible products describe modest, evidence-based effects, not miracle outcomes.
- Keep a note of what you're taking and any changes you notice, so you and your doctor can judge whether it's actually helping.
The Bigger Picture
Food First
It's easy to spend a lot of time researching the "right" supplement while overlooking the changes that tend to matter more. For most people with gout, overall dietary pattern, staying well hydrated, maintaining a healthy weight where relevant, being thoughtful about alcohol — particularly beer — and taking prescribed medication consistently do more for long-term uric acid control than any single supplement is likely to.
Our complete gout diet guide covers this in more depth, including which foods are worth genuinely limiting and which have been unfairly blamed over the years. If you want to go further, our guides to foods to avoid, low-purine everyday choices, and the best fruit for gout — cherries included — go into more specific detail. Alcohol and gout and hydration are also worth a look, since both influence uric acid more consistently than most supplements do. And if you're after meal ideas that fit naturally into this way of eating, our gout-friendly recipes are a good place to start.
None of this means supplements are pointless — it simply means they tend to work best as a small addition to a bigger, more established picture, not as a shortcut around it.
