The 2023 guideline names no form, dose or combination to prefer
The international guideline on polycystic ovary syndrome allows that women may reasonably try inositol, then says no type, dose or combination can be recommended for lack of quality evidence.
What the study found
No form of inositol is recommended over any other
The 2023 international guideline on polycystic ovary syndrome, or PCOS, allows that women may reasonably try inositol, then states that no specific type, dose or combination can be recommended for lack of quality evidence. For fertility it calls inositol experimental.
The caveat · 3 of 13 comparisons had data to pool
A guideline synthesises trials rather than adding any, and only 3 of the 13 comparisons its evidence review assessed had enough studies to pool. The same guideline records that inositol's side effects and safety are not known, and that supplement regulation, dose and quality control differ from those for medicines.
