Effects of inositol in women with polycystic ovary syndrome: an umbrella review of meta-analyses from randomized controlled trials.

Systematic reviewWomens Health Hormone Health

This umbrella review synthesized meta-analyses of RCTs to evaluate the efficacy of inositol for PCOS. Inositol significantly improved hormonal profiles, glycolipid metabolism, and reproductive outcomes compared to placebo, but showed limited effects compared to metformin. The review highlights moderate-quality evidence supporting inositol's benefits, though outcomes based on low-quality evidence require cautious interpretation.
