Myo-Inositol and Insulin-Resistant PCOS: A Natural Approach to Hormone and Cycle Support

Polycystic ovary syndrome (PCOS) is a health problem that continues to affect women and people assigned female at birth all over the world. This complex condition is primarily driven by insulin resistance and often higher than average visceral fat stores which can impair the communication between your brain and reproductive organs regarding the regulation of your hormones. The imbalances in your body as a result of insulin-resistant PCOS can increase your risks of developing health complications, such as metabolic syndrome, diabetes mellitus, heart disease, and even infertility.1 Myo-inositol is a natural sugar alcohol that promotes insulin sensitivity, thereby helping your cells receive their power supply to function optimally. However, people with PCOS are often deficient in myo-inositol. Hence, nurturing its levels through nutrition and supplementation is important in helping your body naturally heal itself and regulate its processes, including your hormone levels.

Understanding PCOS

Polycystic ovary syndrome (PCOS) is a type of endocrine disorder affecting women of reproductive age. It happens when there is a problem with the regulation of your reproductive hormones due to miscommunication between your brain and reproductive organs (a.k.a. your ovaries which sends out signals to your hypothalamus to secrete stimulating hormones). Miscommunication can result from problems hormone synthesis, insulin resistance leading to inadequate delivery of energy to cells, or high body fat stores impairing signaling between cells.3 Unfortunately, this miscommunication can lead to problems with menstruation, blood glucose regulation, ovulation and fertility, and even excess of androgens that can trigger acne and hair growth. In the long run, people with PCOS are at higher risk of developing hypertension, heart disease, or type 2 diabetes.3 Hence, the first-line management of insulin-resistant PCOS is centered around correcting problems with insulin resistance and increasing your cells’ sensitivity to insulin through nutrition and lifestyle changes.

​How Myo-Inositol can Help

A common factor that drives the development and progression of polycystic ovary syndrome (PCOS) is insulin resistance.1 This means that your cells refuse to receive the vehicle (a.k.a. insulin) that delivers the energy in the form of glucose that they need to stay healthy and function optimally. Myo-inositol is a substance naturally present in the body that acts similarly to insulin by promoting the entry of glucose into cells through its ability to use insulin pathways within the cell.2  Although beneficial in decreasing insulin resistance, myo-inositol is excreted more in the urine of people with PCOS, eventually leading to myo-inositol deficiency. Not to worry! Myo-inositol is also naturally present in fruits, vegetables, nuts, and beans.2 Additionally, supplements with myo-inositol as the key ingredient are readily available for purchase.

Safety and Considerations

Myo-inositol is generally safe and effective to use in the management of PCOS. However, its use should be monitored by your primary care provider or naturopathic doctor because gastrointestinal side effects such as nausea, diarrhea, or flatulence may happen with high or unregulated doses.2 Additionally, monitoring is important in ensuring that therapeutic levels of myo-inositol are present in the body.

Ideal Candidates for Myo-Inositol

Aside from people diagnosed with insulin-resistant PCOS, women of reproductive age can take full advantage of the wonders of myo-inositol, especially during conception and pregnancy. Myo-inositol can be taken to prevent the baby from developing neural tube defects or mother from having diabetes during pregnancy.2 Additionally, myo-inositol is proven to improve the quality of your eggs for fertilization by your partner’s or donor’s sperm.2

Choosing Quality Supplements

Just like conventional medications, not all supplements are created equal. The goal should always be nurturing myo-inositol levels that are considered optimal for your unique body. Hence, exploring the wonders of myo-inositol for your health should be guided by an expert who will help you establish a holistic health plan according to your needs, preferences, and case.
