What Makes the 3.6:1 Ratio of Myo + D-Chiro-Inositol Different from 40:1?

The Great Inositol Debate

If you’ve been Googling “inositol for fertility,” you’ve probably stumbled across two numbers: 40:1 and 3.6:1. What gives? And why does the ratio matter?

Here’s the quick answer: while 40:1 is the most common, new research shows that a 3.6:1 ratio of Myo-Inositol to D-Chiro-Inositol may be more effective for certain fertility outcomes. That’s why Pink Stork created 3.6:1 Ratio Myo + D-Chiro-Inositol — a formula designed with science in mind.

Myo-Inositol vs. D-Chiro-Inositol

Let’s back up. Inositol is a nutrient sometimes referred to as “Vitamin B8” (though it’s not officially a vitamin). The two forms most relevant to fertility are:

• Myo-Inositol (1100 mg per serving in Pink Stork’s formula) — supports ovulation, cycle regularity, and egg quality.*

• D-Chiro-Inositol (300 mg per serving) — supports insulin signaling, ovarian function, and hormone balance.*

Both matter. But it’s the ratio that determines how effectively they work together.

Why 3.6:1?

A groundbreaking study published in Gynecological Endocrinology found that a 3.6:1 ratio of Myo-Inositol to D-Chiro-Inositol significantly improved pregnancy and live birth rates compared to the 40:1 blend.†

• Pregnancy rates: +153% higher with 3.6:1

• Live birth rates: +272% higher with 3.6:1

That’s not just impressive — it’s fertility science in action.
