Does turmeric reduce inflammation and joint pain?

What you hear: “Turmeric or curcumin supplements cure inflammation and get rid of joint pain.”

What the studies found

A 2025 pooled analysis of 10 trials (786 people with knee arthritis) found turmeric extract eased pain more than a dummy pill over 4 to 6 weeks and worked about as well as common anti-inflammatory painkillers. But a 2025 review of the 7 published pooled analyses rated them all as very low methodological quality, with 37 of 48 findings resting on extremely low-quality evidence. The US National Center for Complementary and Integrative Health calls the early arthritis evidence positive but says higher-quality studies are needed. Curcumin is also poorly absorbed, because the body takes in little and clears it fast. There is no good evidence it cures inflammation in general.

Take care: Rare but serious liver injury has been reported, often after 1 to 4 months and especially with high-absorption products; avoid supplements in pregnancy and check with a doctor if you take other medicines.

What you could do

If knee arthritis bothers you, a short trial of a standard turmeric product is reasonable, but stop if you notice dark urine, yellow skin or belly pain.

How we judged it

Partly true: Some truth, but oversold as usually said. We judge the claim as it is usually said online, not the habit itself. Trials assign people at random, so they can show cause; observed studies follow people and show a link, not proof. Last checked: October 2026.

The studies, in their own words

1. Hidayat et al. J Rheum Dis 2025

   Curcuma longa benefits knee OA pain and function, being more effective than placebo and comparable to NSAIDs.

2. Chen et al. Front Pharmacol 2025

   Among 48 outcomes assessed, evidence quality was mostly low, with 5 medium-quality, 6 low-quality, and 37 extremely low-quality evidences.

3. NCCIH: Turmeric (accessed Oct 2026)

   The initial evidence is positive; higher-quality evidence is needed to reach definitive conclusions, and more research is needed to understand the impact of bioavailability on curcumin’s effects.

4. Anand et al. Mol Pharm 2007

   Major reasons contributing to the low plasma and tissue levels of curcumin appear to be due to poor absorption, rapid metabolism, and rapid systemic elimination.

5. Akhtar et al. (USP) Pharm Biol 2026

   Reported hepatotoxicity typically occurs after 1 to 4 months of use and generally resolves upon discontinuation; cases of acute liver failure have been reported albeit rarely.
