There are many dedicated doctors and researchers working on behalf of women with PCOS. Dr. Antonio Simone Laganà is one of these dedicated researchers. He works in the Department of Pediatric, Gynecological, Microbiological and Biomedical Sciences at the University of Messina in Italy.
Dr. Laganà has been conducting some very helpful studies around the supplement inositol. If you haven’t yet heard about inositol, then you’ll want to know that inositol is NOT a pharmaceutical drug. It is a naturally occurring substance produced in the human body that belongs to the vitamin B complex group. There are nine different types of inositol and can be found naturally in many foods such as fruits, nuts and beans. It is a precursor to a number of ”signaling molecules” that essentially tell cells how to behave. Of the nine different types of inositol, two have insulin-sensitizing capabilities: myo-inositol and d-chiro-inositol. Dr. Laganà is proactively trying to get the word out about his study findings and has been posting his research studies on my Facebook page. I thought I would summarize his findings for you. Please spread the word and pass this info on to fellow Divas. If you want to discuss these finding with your doctor, be sure to point them to the actual research references provided below. You might also read my post about myo-inositol here.
Here is a summary of Dr. Laganà’s recent studies:
On March 9th, Dr. Laganà published some preliminary data proceeding the 16th World Congress of Gynecological Endocrinology on ovarian function and metabolic factors in women affected by PCOS after treatment with D-chiro-inositol. (1) The study looked at 25 patients affected by PCOS and menstrual irregularities. The patients underwent treatment with 1 g of D-Chiro-Inositol plus 400 mcg of Folic Acid orally for 6 months. After the 6 months there was a statistically significant reduction of the Systolic blood pressure, Gallwey-Ferriman Score, LH, LH/FSH ratio, total Testosterone, free Testosterone, ∆-4-Androstenedione, Prolactin and HOMA Index; in the same patients there was a statistically significant increase of SHBG and Glycemia/IRI ratio. Moreover, there was a statistically significant (64%; p<0.05) post-treatment menstrual cycle regularization.
The study conclusion is d-chiro-inositol is effective in improving ovarian function and metabolism of patients affected by PCOS.
Comparison study between of myo-inositol and D-chiro-inositol
Published on December 19th, 2013, the aim of this work was to compare the effects of myo-inositol and d-chiro-inositol in PCOS. 50 patients, with homogeneous bio-physical features, affected by PCOS and menstrual irregularities participated and were randomly divided into two groups: 25 were treated with 4 g of myo-inositol plus 400 mcg of folic acid orally for six months, 25 with 1 g of d-chiro-inositol plus 400 mcg of folic acid orally for six months. Both groups were analyzed pre-treatment and post-treatment BMI, systolic and diastolic blood pressure, Ferriman–Gallwey score, Cremoncini score, serum LH, LH/FSH ratio, total and free testosterone, dehydroepiandrosterone sulfate (DHEA-S), Δ-4-androstenedione, SHBG, prolactin, glucose/immunoreactive insulin (IRI) ratio, homeostatic model assessment (HOMA) index, and the resumption of regular menstrual cycles.
The study conclusion was that both the isoforms of inositol were effective in improving ovarian function and metabolism in patients with PCOS, although myo-inositol showed the most marked effect on the metabolic profile, whereas d-chiro-inositol reduced hyperandrogenism better.
Summary of Findings
Dr. Laganà has given me permission to post his editorial Know your Enemy: The Rationale of Using Inositol in the Treatment of Polycystic Ovary Syndrome. This article is a nice summary of all the the research findings on myo-inositol and d-chiro inositol.
Just to be sure, I emailed the following questions to Dr. Laganà-
Amy: “There is much confusion among women with PCOS as to what type of inositol to use for PCOS. It seems that myo is best for egg quality and trying to conceive and d-chiro is best for lowering androgens. Do you have any recommendations on what type to use?” Here was his response,
Dr. Lagana: “According to our recent data analysis, both the isoforms of inositol are effective in improving ovarian function and metabolism in patients with PCOS, although myo-inositol showed the most marked effect on the metabolic profile, whereas D-chiro-inositol reduced hyperandrogenism better.”
Amy: “Can and should a woman with PCOS take both forms of inositol – myo and d-chiro?”
Dr. Laganà: “Despite currently there is no clear evidence to support the treatment with a combination of myo- and d-chiro-inositol, there is a paper published by Nordio & Proietti in 2012 (http://www.ncbi.nlm.nih.gov/pubmed/22774396), which found that the combined therapy with myo-inositol and D-chiro-inositol reduces the risk of metabolic disease in PCOS overweight patients compared to myo-inositol supplementation alone. Neverthless, further data are needed to clarify better the situation. In my opinion it will be mandatory in future to use a “tailored treatment” basing on different bio-hormonal parameters of each patient.”
Amy: “Can myo-inositol and d-chiro-inositol be taken if a women is pregnant or nursing?”
Dr. Laganà: To date, there are no reports about side effects of Inositol administration during pregnancy and breastfeeding. Accumulating evidence seems to suggest that Inositol supplementation during pregnancy may:
Thanks Dr. Lagana for all your efforts in helping women with PCOS!
