Myo-inositol Scientific Studies

Scientific Studies involving Myo-inositol

The effects of supplementing with myo-inositol have been investigated during the following clinical studies:

This study's results showed that 88% of the study participants had at least one normal menstrual cycle and 72% of those women maintained normal ovulation, after the study. 40% of study participants achieved pregnancy during the 6 month study.

Epub 2007 Oct 10. PubMed PMID: 17952759.

This study showed that plasma levels of insulin, LH and FSH were significantly reduced after 12 weeks of continued usage of myo-inositol. Insulin sensitivity was also significantly improved. For the PCOS patients who had no period or very irregular menstrual periods, menstrual cycles were restored by the end of the 12 weeks.

A randomized study. Gynecol Endocrinol. 2013 Jan 22. [Epub ahead of print] PubMed PMID: 23336594.

In a comparison of myo-inositol and D-chiro-inositol, this study showed that only myo-inositol was able to improve oocyte and embryo quality.

"These data suggest that myoinositol may be useful in the treatment of PCOS patients undergoing ovulation induction, both for its insulin-sensitizing activity, and its role in oocyte maturation."
