First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether inositol, a natural dietary supplement, can lower high testosterone levels in women with polycystic ovary syndrome (PCOS). 154 women took either a placebo or one of three doses of inositol powder for a set period. Researchers measured changes in testosterone, insulin, and glucose tolerance to see if the supplement helps control the condition.

What this could lead to
If it works, this could point toward a simple, over-the-counter supplement to help manage hormone imbalances in women with PCOS.
What could go wrong
This is a small, early-phase trial with only 154 participants. The supplement may not significantly improve symptoms, and results may not apply to all women with PCOS.
