Inositol

Inositol is a vitamin-like compound your body uses in cell signaling, especially in how cells respond to insulin and to brain chemicals such as serotonin. The two main forms are myo-inositol and D-chiro-inositol. Inositol is popular with women for healthy ovarian function and regular cycles, and with anyone looking for support for healthy insulin signaling and a calm, balanced mood.

This collection includes myo-inositol powders and capsules, D-chiro-inositol, 40:1 combination formulas and choline and inositol blends from practitioner brands such as Pure Encapsulations, Theralogix, Klaire Labs, Vital Nutrients, Jarrow, Douglas Labs and NOW.

How to Choose an Inositol Supplement

• Myo-inositol: The most common and most studied form. Powders such as Inositol (powder) by Pure Encapsulations, our top seller, make larger daily amounts easy.
• D-chiro-inositol: A second form your body makes from myo-inositol, used in smaller amounts. D-Chiro-Inositol by Klaire Labs is an example.
• 40:1 blends: Combine myo- and D-chiro-inositol in the 40 to 1 ratio found naturally in the body. Ovasitol by Theralogix is a popular choice for women.
• Powder or capsules: Inositol is often taken in gram amounts, so powder is more practical. It has a mildly sweet taste and mixes easily into water.
• Choline and inositol: Combination products pair inositol with choline for liver and brain support. See choline.

Many people take inositol in two divided doses, morning and evening, mixed into water. Start with a smaller amount and increase over a week or two for comfort. Talk with your practitioner if you are pregnant, trying to conceive or take blood sugar medication. See also women's health.
