Inositol is a natural carbohydrate that acts as a key messenger for hormonal signals, including insulin. For supporting hormonal balance, research points to a specific combination as the most effective: Myo-inositol (MI) and D-Chiro-inositol (DCI).
When taken as a supplement, this blend helps restore the body's optimal 40:1 ratio. This is crucial for improving insulin sensitivity and regulating hormonal pathways, especially for managing conditions like PCOS. Many formulas also include folic acid or vitamin D3 for added support.

All Reviews
Wholesome Story Myo-Inositol & D-Chiro Inositol (40:1)
- 40:1 myo + d-chiro ratio
- 4 capsules per serving
Wholesome Story is an accessible 40:1 capsule option with strong review volume and easy retail availability, but four capsules a day is still the main tradeoff.
Theralogix Ovasitol Inositol Powder
- 40:1 myo + d-chiro ratio
- 2 servings daily
Ovasitol is still one of the easiest 40:1 inositol products to recommend because the formula is clean, the certification story is strong, and the powder format avoids capsule overload.
