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.
