What the evidence says
Likely helps
Curcumin appears to help in 4 of 5 studies with measurable effects — the evidence leans clearly favourable.
Most evidence is from high-quality meta-analyses and randomised trials published 1980–2027 with a typical study size of 101 participants.

Liver healthIn fatty liver disease, small trials mostly from Iran and Thailand show less liver fat on ultrasound and small drops in liver enzymes, but a 2024 pooling of 15 trials found no effect on ALT, and severe liver injury has been reported, so it is not a general liver tonic · 8-12 weeks

1Knee osteoarthritis pain and stiffnessMeta-AnalysisCited 6×n=4,599 · very large study2025
In plain English: However, further large-scale, well-designed randomized controlled trials (RCTs) are needed to confirm these findings, particularly those that include more standardized dosages and formulations, as well as to evaluate their long-term efficacy.
Zhang Y et al. · Nutrients (2025)
Bayesian rankings indicated Boswellia had the highest probability of being most effective for pain and stiffness, with krill oil and curcumin showing potential for function improvement.
Conclusions: Nutritional supplements, particularly Boswellia, appear to be effective and well-tolerated for improving KOA symptoms and function.
These results suggest that certain supplements may be useful as part of non-pharmacological KOA management.
2Depressive disorder symptomsMeta-AnalysisCited 5×n=17,437 · very large study2025
In plain English: This extensive systematic review and NMA of nutraceuticals for treating depressive disorders indicated a number of nutraceuticals that could offer benefits, either as adjuncts or monotherapies.
Cheng YC et al. · Psychological medicine (2025)
Network meta-analysis of 192 trials in 17,437 adults with depressive disorder, covering 44 nutraceuticals.
Curcumin added to antidepressants outperformed antidepressants alone (SMD 1.03, 95% CI 0.55 to 1.51).
Curcumin on its own was not clearly better than antidepressants, since its confidence interval crossed zero (SMD 0.62, -0.17 to 1.40), and most nutraceuticals were tolerated about as well as placebo.
3Arthritis symptoms and inflammationMeta-AnalysisCited 113×n=2,396 · very large study2022
In plain English: Curcumin and Curcuma longa Extract may improve symptoms and inflammation levels in people with arthritis.
Zeng L et al. · Frontiers in immunology (2022)
Meta-analysis of 29 RCTs in 2,396 people with ankylosing spondylitis, rheumatoid arthritis, osteoarthritis, juvenile idiopathic arthritis or gout, at 120 to 1500 mg a day for 4 to 36 weeks.
Curcumin and Curcuma longa extract improved pain and inflammation and were safe in all studies.
The trials were few and of low quality, so the authors ask for the results to be read carefully.
