Inositol

Inositol is a vitamin-like compound found in many foods and used widely in nutritional therapy to support mood, energy, hormone communication and metabolic balance. It exists in several forms, with myo-inositol and D-chiro inositol being the most commonly used.


Although often associated with women’s health, inositol plays a role in many systems throughout the body, including insulin signalling and the nervous system. It can be a gentle, supportive addition when used alongside a balanced diet, stress management and lifestyle foundations.

What It Is

What It Is

Inositol is a naturally occurring compound sometimes referred to as a “vitamin-like” substance. It plays an important role in:

  • cell signalling

  • insulin communication

  • neurotransmitter balance

  • reproductive hormone pathways

  • lipid metabolism


There are multiple forms, but myo-inositol is the most abundant in the body. It works closely with pathways involved in mood, energy and hormonal balance.

What It’s Used For

Inositol supplements are commonly used to support:

  • mood and emotional balance

  • cravings and blood sugar regulation

  • hormonal communication between the brain and ovaries

  • menstrual cycle regularity

  • energy and fatigue

  • general metabolic wellbeing


Different forms (or combinations) may be used depending on individual goals.

What the Evidence Says

Research suggests that inositol, particularly myo-inositol:

  • supports insulin signalling

  • may help regulate menstrual cycles in some individuals

  • can support emotional wellbeing

  • may reduce cravings when paired with balanced meals

  • plays a key role in cell signalling pathways that influence hormones


Studies also show potential benefits in:

  • nervous system health

  • metabolic balance

  • reproductive hormone communication


However, responses vary and inositol works best when combined with dietary and lifestyle support.

When It Can Be Helpful

Inositol may be worth considering if you:

  • experience cravings or dips in energy between meals

  • feel emotionally overwhelmed or anxious

  • have irregular cycles alongside a nutrition-first approach

  • are exploring women’s health and hormone balance with guidance

  • follow a plan to support metabolic wellbeing

  • feel “wired but tired” or overstimulated

  • have been recommended inositol through hormone or metabolic testing


It is often used as part of a broader support plan — not a standalone solution.

When Caution Is Needed

Although generally well tolerated, caution is needed if:

  • you take medication for mood or mental health

  • you are pregnant or breastfeeding (seek guidance on dose)

  • you have very low blood sugar or frequent dizziness

  • you react strongly to supplements affecting insulin signalling

  • you are taking high-dose blends without professional guidance


Some people may experience temporary digestive changes when starting inositol.

Why It’s Not Always the First Step

Inositol works best when foundational factors support hormone and metabolic balance.
Before considering supplementation, it’s helpful to explore:

  • stable blood sugar through balanced meals

  • regular protein intake

  • reducing ultra-processed foods

  • stress management

  • consistent sleep

  • appropriate movement

  • fibre intake, which influences hormone communication


These foundations often make a bigger difference than supplements alone.

Nutrition Support

Food sources naturally rich in inositol or supportive of its pathways include:

  • citrus fruits

  • whole grains

  • beans and lentils

  • nuts and seeds

  • cantaloupe

  • kiwi

  • brown rice


Lifestyle support includes:

  • balanced meals spaced regularly

  • adequate sleep

  • stress reduction techniques

  • regular movement

  • mindfulness or nervous system support practices


Inositol supplements can complement these foundations when needed.
