Myo-inositol

What is Myo-inositol?

Myo-inositol is a sugar alcohol belonging to the group of sugar alcohols and is a form of inositol. It is a naturally occurring substance found in many foods, such as fruit, beans, nuts, and whole grain products. Myo-inositol has gained significant attention in health and nutrition due to its potential benefits for hormonal balance and insulin sensitivity, especially in women with polycystic ovary syndrome (PCOS) and those trying to improve their fertility.

How does it work in the body?

Myo-inositol works by affecting several biological processes in the body. It is an important component of cell membranes and plays a key role in cell signalling. Myo-inositol helps regulate insulin receptors, which can lead to improved insulin sensitivity. This is particularly important for women with PCOS, where insulin sensitivity is often impaired. By enhancing insulin signalling, Myo-inositol can also support ovulation and hormonal balance.

Scientific benefits

Several studies have investigated the benefits of Myo-inositol, particularly in relation to PCOS and female fertility. A review article published in the European Journal of Endocrinology showed that Myo-inositol can improve ovulation frequency and increase pregnancy chances in women with PCOS. Another study in the Journal of Ovarian Research demonstrated that Myo-inositol can help regulate menstrual cycles and reduce symptoms of hyperandrogenism, which is common in women with PCOS.

Further research in Human Reproduction has shown that Myo-inositol can improve egg quality in women undergoing fertility treatments. By supporting hormonal balance and insulin sensitivity, Myo-inositol can also contribute to a more regular menstrual cycle, which is crucial for fertility.

Dosage and recommendations

The recommended dosage of Myo-inositol varies depending on individual needs and health status. Typically, a dose of 2 to 4 grams per day is recommended, usually divided into two doses. It is important to consult a doctor or dietitian before starting a Myo-inositol supplement to ensure it is appropriate for your specific situation.

Best sources and forms

Myo-inositol can be consumed through supplements or diet. Some of the best natural sources include:

• Fruits such as oranges and melons
• Beans, such as black beans and chickpeas
• Nuts, like almonds and walnuts
• Whole grain products, such as oats and brown rice

Myo-inositol supplements are available in various forms, including powder, capsules, and tablets. The powder can easily be mixed into smoothies or other drinks to facilitate intake.

Side effects and warnings

Myo-inositol is generally safe to use and has few reported side effects. Some individuals may experience mild gastrointestinal discomfort, such as stomach upset or diarrhoea, especially at higher doses. It is important to start with a lower dose and gradually increase it to minimise the risk of side effects. Pregnant or breastfeeding women should consult a doctor before taking Myo-inositol.
