Effect of curcumin supplementation on symptoms of anxiety: A systematic review and meta-analysis of randomized controlled trials


Summary


Background and aim

Curcumin is a polyphenolic natural compound that has been used to treat various ailments such as symptoms of anxiety. However, the findings of studies regarding the anti-anxiety properties of curcumin are controversial. This review aims to evaluate if there are clinical benefits of curcumin in patients with symptoms of anxiety.


Methods

PubMed, Embase, Web of Science, and the Cochrane Library were retrieved to collect randomized controlled trials (RCTs) from the database inception to August 16, 2023. The random-effects model was used to estimate the standard mean difference (SMD).


Results

A total of eight RCTs involving 567 participants were included in the analysis. A pooled analysis showed a significant effect of curcumin on anxiety symptoms (SMD: −1.56; 95% CI: −2.48, −0.64, p < 0.001; I2 = 95.6%, p-heterogeneity< 0.001).


Conclusion

Present meta-analysis demonstrated that curcumin intake might contribute to alleviation of anxiety disorder. Due to the limited number of studies included, it is necessary to conduct more high-quality studies to confirm the clinical efficacy of curcumin.
