Ingredient Spotlight: Myo-Inositol & D-Chiro Inositol
WHAT ARE THEY?
Myo-Inositol (MI) and D-Chiro Inositol (DCI) are two forms of inositol, a naturally occurring sugar alcohol that belongs to the B-vitamin family. Your body produces inositol, and it's also found in foods like wholegrains, legumes, and citrus fruits. While they're closely related, each form plays a distinct role in the body, and together they work as a powerful team for hormonal health.
Myo-Inositol: The insulin sensitiser.
The most abundant form in the body. Plays a key role in insulin signalling and supporting healthy egg development in the ovaries.
D-Chiro Inositol: The androgen regulator.
Found in lower concentrations. Works downstream to regulate androgen (testosterone) levels and support glucose metabolism in tissues.
WHY THEY MATTER FOR HORMONE SUPPORT
- Cycle regularity: Supports more regular menstrual cycles by improving the hormonal signalling that drives ovulation, particularly in women with irregular cycles.
- Insulin sensitivity: Insulin resistance is a root driver of hormonal imbalance in many women. Inositol helps cells respond to insulin more effectively, reducing its knock-on effects on hormones.
- Androgen balance: Elevated androgens (like testosterone) can disrupt cycles and contribute to symptoms like acne and excess hair growth. DCI helps keep these in check.
- PMS & mood support: Myo-Inositol has been studied for its role in supporting mood and reducing PMS symptoms, linked to its effect on serotonin signalling pathways.
- Egg quality: Myo-Inositol is concentrated in follicular fluid and plays a direct role in egg maturation and quality - important for both natural conception and fertility treatment.
- PCOS support: One of the most researched natural interventions for PCOS. The MI + DCI combination addresses multiple root causes of the condition simultaneously.
THE RATIO THAT MATTERS
Not all inositol supplements are equal. The ratio of Myo-Inositol to D-Chiro Inositol is critical.
Research shows a 40:1 ratio of Myo-Inositol to D-Chiro Inositol mirrors the body's natural plasma ratio and delivers the best hormonal outcomes. Too much DCI can actually have the opposite effect on egg quality — which is why the ratio matters as much as the dose.
Hormonal imbalance rarely has a single cause and that's exactly why we chose the MI + DCI combination. Rather than addressing one symptom, this duo works at a root level to support insulin signalling, regulate androgens, and restore the hormonal rhythm your cycle depends on. We formulated at the clinically studied 40:1 ratio.
