D-Chiro Inositol

Myo-inositol's partner — powerful in small, precise amounts.

What it is

D-chiro inositol (DCI) is made in the body by converting myo-inositol via an insulin-dependent enzyme. It plays a role in glycogen storage and androgen synthesis. Because the ovary needs far more myo than DCI, the ratio matters more than the raw dose.

Why it’s used

Supports glucose handling and healthy androgen balance.
Restores the physiologic 40:1 plasma ratio when paired with myo-inositol.
Used alongside myo-inositol rather than on its own.

What research says

Research shows the healthy human plasma myo:DCI ratio is roughly 40:1, and formulations matching that ratio outperformed DCI-heavy blends on ovulation outcomes.
High-dose DCI alone has been associated with a 'DCI paradox' — worse oocyte quality at excessive doses — which is why balanced ratios are standard.

Typical dose: 100 mg daily alongside 4,000 mg myo-inositol (40:1).
