Why it’s used

Taken to support joint comfort and as a general anti-inflammatory or antioxidant supplement.

What the evidence is for

joint pain and function in osteoarthritis.

What the evidence says

A 2022 systematic review and meta-analysis pooled 29 randomized controlled trials (2396 participants) covering five types of arthritis, including osteoarthritis, with curcumin or Curcuma longa extract doses of 120-1500 mg daily for 4-36 weeks. The authors report that treatment improved pain severity and markers of inflammation, but the clinical outcomes (pain, symptom severity) are not reported separately for osteoarthritis alone, and the trials span multiple arthritis diagnoses rather than isolating OA. The authors themselves caution that conclusions need to be interpreted carefully because of low study quality and small trial numbers, despite the overall positive direction of effect.

Dose studied

0.5–2 g — curcumin extract doses used in osteoarthritis trials.

Context

Trials showing benefit have generally used curcumin extract doses in the range of several hundred to about 1-2 grams per day, often paired with an absorption enhancer such as piperine or a lipid-based delivery system; trial durations are typically a few months.
