What Are the Best Supplements for Reducing Inflammation?

Which Supplements Have the Strongest Evidence for Reducing Inflammation?

The supplements with the most consistent evidence for reducing chronic inflammation are omega-3 fatty acids (particularly EPA and DHA from fish oil) and curcumin, the active compound in turmeric. Several others — including ginger extract, boswellia, and quercetin — show promising results, though the human evidence is generally less robust. That said, no supplement meaningfully outperforms lifestyle fundamentals when it comes to lowering systemic inflammation over time.

This article focuses specifically on what the evidence says about anti-inflammatory supplements, how they work, and how to use them sensibly. For a broader view of where supplements fit within a longevity strategy, see our evidence-based longevity blueprint.

How Chronic Inflammation Affects Aging and Healthspan

Why Inflammation Matters for Longevity

Acute inflammation is a normal, protective response. Chronic low-grade inflammation, however, is a different problem. Research consistently links persistently elevated inflammatory markers — such as CRP, IL-6, and TNF-alpha — with accelerated biological aging, cardiovascular disease, metabolic dysfunction, cognitive decline, and reduced healthspan.

This phenomenon is sometimes called “inflammaging” — the gradual rise in baseline inflammation that tends to occur with age. Importantly, it is not inevitable. Modifiable factors including poor sleep, sedentary behaviour, excess visceral fat, poor diet quality, smoking, and chronic stress are among the main drivers. Addressing those factors directly tends to produce a larger and more durable reduction in inflammation than any supplement alone.

That said, once lifestyle foundations are in place, targeted supplementation may provide additional support — particularly for people with persistently elevated inflammatory markers or limited dietary intake of key nutrients.

The Best Evidence-Based Anti-Inflammatory Supplements

Omega-3 Fatty Acids (EPA and DHA)

Omega-3 fatty acids — particularly EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) from fish or algae oil — are among the most thoroughly studied anti-inflammatory nutrients available. Research consistently shows that regular supplementation reduces circulating levels of pro-inflammatory markers, including CRP and IL-6, and supports cardiovascular and joint health.

The mechanism is well understood. EPA and DHA compete with arachidonic acid in inflammatory pathways, shifting the balance toward less inflammatory signalling molecules known as resolvins and protectins. As a result, systemic inflammation tends to decrease with consistent intake over weeks to months.

Typical doses studied in clinical trials range from 1–4g of combined EPA and DHA daily. For general inflammation support, doses at the lower end of this range are commonly used. Choosing a high-quality, third-party tested fish oil or algae-based supplement reduces the risk of contaminants such as heavy metals or oxidised fats.

Curcumin (from Turmeric)

Curcumin, the primary bioactive compound in turmeric, has demonstrated anti-inflammatory effects across multiple human trials. It appears to inhibit NF-κB, a key signalling pathway that drives the production of pro-inflammatory cytokines. Evidence suggests it may also help modulate oxidative stress, which is closely linked to chronic inflammation.

However, curcumin has poor bioavailability on its own. In practice, this means that standard turmeric powder provides minimal active compound. Formulations that include piperine (black pepper extract) or use phospholipid complexes such as Meriva significantly improve absorption. Without enhanced bioavailability, the benefits seen in trials are unlikely to translate to ordinary turmeric capsules.

Human evidence supports modest but meaningful reductions in inflammatory markers at doses ranging from 500–1500mg of curcumin daily, particularly in people with elevated baseline inflammation related to metabolic conditions or joint disease.

Ginger Extract

Ginger contains several active compounds — including gingerols and shogaols — that inhibit similar inflammatory pathways to NSAIDs, though with considerably less gastrointestinal risk. Research suggests it can reduce CRP and other inflammatory markers, and some trials support its use in conditions involving joint inflammation.

In contrast to omega-3s and curcumin, the human evidence base for ginger is smaller and less consistent. It remains a reasonable supporting option, particularly for those who tolerate it well, but it is not a primary anti-inflammatory supplement in the same category as omega-3s.

Boswellia (Indian Frankincense)

Boswellia serrata extract works through a distinct mechanism: it inhibits 5-LOX (5-lipoxygenase), an enzyme involved in the production of leukotrienes, which are potent inflammatory mediators. Several clinical trials suggest it can reduce markers of inflammation and improve symptoms in conditions such as osteoarthritis.

Evidence is generally positive but limited to shorter-duration trials. Overall, boswellia is one of the more credible secondary options for inflammatory support, particularly for joint-related inflammation.

Quercetin

Quercetin is a flavonoid found in foods such as onions, apples, and berries. It has demonstrated anti-inflammatory and antioxidant properties in cell and animal studies. However, human evidence remains limited, and bioavailability is variable. It is sometimes included in broader longevity supplement stacks, but its standalone anti-inflammatory evidence is less compelling than omega-3s or curcumin at this stage.

How to Choose and Use These Supplements Wisely

Prioritise Quality and Bioavailability

Supplement quality varies considerably. For omega-3s, look for products that specify EPA and DHA content clearly, are third-party tested, and have low oxidation levels. For curcumin, bioavailability-enhanced forms are essential — standard turmeric extract provides little active compound. For ginger and boswellia, standardised extracts with defined active compound percentages are preferable to generic powders.

Third-party certification from organisations such as NSF International or USP provides additional assurance of purity and label accuracy — a practical step worth taking when choosing any supplement.

Combining Supplements

Combining omega-3s and curcumin is a reasonable approach, as they act through partially different mechanisms. In practice, this combination is commonly used and generally well tolerated. However, combining multiple anti-inflammatory supplements does not automatically multiply benefits, and more is not always better. Starting with one or two well-evidenced options and monitoring response is a sensible starting point.

Supplements should be viewed as supporting tools within a wider longevity strategy — not as primary interventions. Learn more in our complete guide to longevity.

Risks, Interactions, and Limitations

Most anti-inflammatory supplements are well tolerated at standard doses. That said, relevant risks exist and should be considered before starting.

High-dose omega-3 supplementation (above 3–4g daily) can increase bleeding time and may interact with anticoagulant medications such as warfarin. Curcumin may affect drug metabolism via CYP450 enzymes and should be used cautiously alongside certain medications. Ginger and boswellia are generally low-risk at recommended doses, though digestive discomfort is occasionally reported.

Importantly, supplements are not a substitute for medical treatment in conditions driven by significant or pathological inflammation. Anyone with an underlying inflammatory condition, or taking prescription medications, should consult a healthcare professional before adding new supplements to their regimen.

There is also a broader limitation worth acknowledging: most supplement trials are relatively short-term, often conducted in specific clinical populations, and frequently industry-funded. As a result, the long-term effects of chronic supplementation in generally healthy people are not always well characterised. Current evidence supports their use as reasonable adjuncts — not as certainties.

Conclusion

Among available supplements, omega-3 fatty acids and curcumin have the strongest evidence for reducing chronic low-grade inflammation — a key driver of accelerated aging and reduced healthspan. Secondary options such as ginger and boswellia may offer additional support, though the human evidence is less consistent.

In practice, supplements are most useful when added on top of a strong lifestyle foundation. Sleep quality, regular physical activity, body composition, and diet quality all have larger and better-evidenced effects on systemic inflammation than any supplement currently available. Choosing high-quality, bioavailability-optimised products and using them at evidence-based doses is the most sensible approach.
