Curcumin: Arthritis Trials, Not Longevity
Curcumin: a meta-analysis of 29 RCTs found improved pain and inflammation in arthritis, with low-quality trials; no evidence it extends life.

Quick verdict
A 2022 meta-analysis of 29 RCTs (2,396 people, 5 types of arthritis) found curcumin or turmeric extract may improve symptoms and inflammation, but the trials were low in quality and small in number, so the authors urged careful interpretation. No trial we found shows a longevity benefit.

The short answer: curcumin’s best-supported use is arthritis symptoms, and even that is cautious. A 2022 meta-analysis of 29 randomised trials (2,396 people, five types of arthritis) found curcumin or turmeric extract may improve inflammation and pain, but the authors warned the trials were low in quality and few. We found no trial showing a longevity benefit. Talk to your doctor; turmeric products have been linked to serious liver injury in case reports (below), and supplements can interact with medicines, so ask a pharmacist.
What the evidence shows
Grade: Emerging (arthritis symptoms); not shown for longevity.
| Question | Evidence | Limit |
|---|---|---|
| Arthritis symptoms | 29 RCTs, 2,396 people: improved inflammation and pain; authors reported it safe in all included studies (but see the liver case series below); doses 120 to 1,500 mg for 4 to 36 weeks | Low quality and quantity of RCTs per the authors |
| Longevity | None found | No claim made |

Safety: liver injury reports
A case series from the US Drug-Induced Liver Injury Network reported ten cases of liver injury linked to turmeric products enrolled between 2004 and 2022, all since 2011 and six since 2017. Eight were women; median age 56; injury was mainly hepatocellular; five were hospitalised and one died of acute liver failure. Turmeric was confirmed in all 7 products tested and 3 also contained piperine (black pepper). Seven of ten patients carried the HLA-B*35:01 gene variant, which is far more common in these cases than in the general population (allele frequency 0.450 against 0.056 to 0.069). Ten cases cannot give a rate, but they are why anyone with liver disease should ask a doctor first.
Price of a capsule inside the trial range
Read from Jarrow Formulas’ product pages on 29 Sept 2026, USD, before shipping. The meta-analysis pooled trials using 120 to 1,500 mg; one 500 mg capsule a day sits inside that range, it is not a recommendation. Absorption forms differ, so prices are not like for like.
| Product | Price | Amount per capsule (from product name) | Cost of one capsule a day for 30 days |
|---|---|---|---|
| Jarrow Curcumin 95 | $28.99 for 60; $49.99 for 120 | 500 mg | $14.50 (60) or $12.50 (120) |
| Jarrow Curcumin Phytosome | $29.99 for 60; $49.99 for 120 | 500 mg | $15.00 (60) or $12.50 (120) |
We did not cost other brands: label amounts were unclear on the pages we read.
Who it suits, who should skip it
Reasonable to discuss with a doctor if you have osteoarthritis or another arthritis and want to ask about curcumin alongside treatment, knowing the trials were low quality.
Skip it, or ask first, if you have liver disease or have had abnormal liver tests, take prescription medicines (ask a pharmacist about interactions), or want it for longevity: no trial shows that. See omega-3 and quercetin and fisetin.

Common questions
Does curcumin help arthritis?
Possibly. A 2022 meta-analysis of 29 RCTs with 2,396 participants across five types of arthritis found curcumin and Curcuma longa extract improved inflammation and pain severity, with doses from 120 to 1,500 mg for 4 to 36 weeks, but the authors said the trials were low in quality and few, so conclusions need careful interpretation.
Does curcumin extend lifespan?
No human trial we found shows that. This page makes no longevity claim.

- Sourcing pass: removed unsourced longevity, bioavailability and dosing claims; kept the arthritis meta-analysis and its quality caveat.
