Myo Inositol

If you’ve been researching PCOS support, insulin resistance, or hormonal balance in Australia, you’ve probably come across the word inositol — especially myo-inositol. But what exactly is it, and why is it getting so much attention? Let’s break it down.

What is Inositol?

Inositol is a type of sugar that your body naturally produces. It’s found in many foods (like fruits, beans, grains, and nuts) and helps with cell signalling, hormone balance, and nerve function. While often called "vitamin B8," it’s technically not a vitamin. The two most studied forms are myo-inositol and D-chiro inositol, both known for their role in women’s health.

What is Myo-Inositol Used For?

Myo-inositol is particularly known for:

• Supporting insulin sensitivity

• Promoting ovulation and menstrual regularity

• Improving egg quality in women with PCOS

• Reducing sugar cravings and mood swings linked to hormonal imbalances

In Australia, myo-inositol is gaining popularity as a gentle, science-backed supplement for women managing PCOS and hormonal health.

How Does Myo-Inositol Help with PCOS?

For women with PCOS, insulin resistance plays a big role in symptoms like irregular cycles, acne, excess hair growth, and weight gain. Research shows that myo-inositol can help improve insulin signalling, reduce androgen levels, and support more regular ovulation — all without harsh medications.

 

Why Do We Use a 40:1 Myo-Inositol to D-Chiro Inositol Ratio?

In healthy ovaries, the natural balance is approximately 40:1 myo-inositol to D-chiro inositol. Myo-inositol and D-chiro inositol have distinct roles: myo-inositol is essential for glucose uptake and FSH (follicle-stimulating hormone) signalling, while D-chiro inositol primarily supports glycogen synthesis and insulin-driven androgen production.

 In PCOS, the body may alter this balance, reducing myo-inositol availability in the ovaries, which can disrupt FSH signalling and contribute to hormonal imbalances. Supplementing in the same 40:1 ratio has been shown to restore metabolic and ovarian health more effectively than either form alone. Studies show improvements in ovulation, insulin resistance, and pregnancy rates with this combination.

Benefits Beyond PCOS

While PCOS is the headline act, myo-inositol may also help with:

• Supporting mood (potentially balancing serotonin and dopamine)

• Reducing anxiety and panic symptoms

• Supporting metabolic health in women with gestational diabetes

Additional Benefits: Mood, Fertility, and Muscle Health

Mood and Mental Wellbeing

Research suggests that myo-inositol may support mood by influencing neurotransmitters like serotonin and dopamine. It’s being explored as a gentle aid for symptoms of depression, anxiety, and panic disorders, helping to regulate emotional balance alongside other treatments.

Fertility Support

For women trying to conceive, particularly those with PCOS, myo-inositol has shown promise in improving egg quality, promoting regular ovulation, and supporting a healthy menstrual cycle — all essential for fertility health.

Muscle and Metabolic Health

While less commonly discussed, myo-inositol plays a role in glucose metabolism, which indirectly benefits muscle function. My improving insulin sensitivity, it may help the body use glucose more effectively during physical activity and support overall energy metabolism.

Is Myo-Inositol Safe?

For most people, yes. Research suggests it’s safe at standard doses and well-tolerated. Mild side effects may include nausea, bloating, or headache. Always chat with your healthcare provider, especially if you’re pregnant, breastfeeding, or on medications.

How to Use Myo-Inositol in Australia

You can find myo-inositol supplements in powder or capsule form. Look for formulas that:

• Contain both myo- and D-chiro inositol in a 40:1 ratio

• Are paired with activated folate and vitamin D for extra PCOS support

• Are from a trusted Australian brand

Final Thoughts: Gentle, Not Perfect

If you’re navigating PCOS, insulin resistance, or hormonal ups and downs, remember: you’re not broken. Myo-inositol isn’t a magic cure, but it’s a gentle, evidence-backed ally to help you support your body, rebuild trust, and feel more at home in yourself. Inositol is not a medication. You should always follow your medical advice from your doctors and dietitians.
