PCOS: Should I be taking Myo-inositol?

Ashley's picture

Polycystic Ovarian Syndrome is an ovulatory disorder impacting nearly 1.4 million Canadians. It is associated with a range of symptoms including irregular cycles or amenorrhea, acne, hirsutism, hair loss, and more.

PCOS is a “syndrome” which means there are a range of differing symptoms. This means two people can be diagnosed with PCOS but have different clinical symptoms. Therefore a proper assessment is the first step to figuring out the best way to support individual PCOS cases.

 
PCOS and Insulin Resistance

It is estimated that between 70-80% of PCOS patients have insulin resistance - fasting insulin and fasting glucose should be screened in all PCOS patients.

In insulin resistance, the cellular environment has a difficult time responding to insulin after eating. This results in too much sugar and too much insulin circulating in the blood. 

High levels of insulin can cause problems in the ovaries, leading to excess androgen production (testosterone), inflammation, and oxidative stress

 
What is Myo Inositol?

Myo-Inositol is a messenger found inside the cells and used in blood sugar regulation It helps glucose enter the cells in response to insulin. In general, there are higher levels of Myo Inositol found in the ovaries compared to other areas. However, in PCOS, there appears to be a deficiency of Myo-inositol within the ovaries.

A deficiency of Myo-inositol is also thought to be a contributor to poor egg quality.

 

Benefits of MyoInositol in PCOS patients

Supplementation of Myo-inositol in patients with PCOS was shown to improve symptoms of excess androgens- i.e. facial hair growth, acne, and serum testosterone levels. 

Myo-inositol improved other metabolic parameters such as triglycerides and insulin sensitivity.

Supplementation improved clinical pregnancy rates in those undergoing IVF.

 

Metformin vs. Myo-Inositol

The conventional treatment of insulin resistance in PCOS is metformin. When studied head-to-head against metformin, Myo-inositol was as effective or more effective at normalizing:

  • Ovulation rates
  • Live birth rates
  • Fasting insulin
  • Insulin resistance
  • Serum testosterone
  • BMI

The only difference was tolerance - metformin can cause GI upset and diarrhea, as well as B12 deficiency.

 
So should I be taking MyoInositol? 

The research looks very promising, it’s generally very well tolerated with no toxic effects reported. Talk to an Acubalance practitioner to learn if it’s suitable for you.
