Following clinical evidence, our Inositol Plus dietary supplement is formulated to match your body's natural 40:1 ratio of Myo-Inositol (MI) and D-Chiro Inositol (DCI) with 2,000 mg Myo-Inositol and 50 mg D Chiro-Inositol per serving.‡

"I recommend inositol supplementation to support menstrual cycle regularity and hormone balance."

We do our homework. See the research behind our Inositol Plus supplement.

Inositol Plus was thoughtfully developed by experts (who are also moms).

Our Inositol Plus supplement was carefully developed in collaboration with our Medical Advisor and board-certified OBGYN, Dr. Kenosha Gleaton, using peer-reviewed studies that reflect the latest research.

We are committed to manufacturing excellence. Every batch of vitamins is tested for product integrity.

All of our vitamins are made in an FDA Registered and Inspected Facility, which meets or exceeds FDA 21 CFR 111 guidelines.

In addition to testing the raw material components of our vitamins to ensure their purity and accuracy, we also test each batch after it is produced to ensure final product integrity and quality. Testing includes a chemical analysis to ensure accuracy, a microbial analysis (salmonella, E. coli, yeast, and mold) and a heavy metals test (including arsenic, cadmium, and lead). 

Inositol Plus is free of artificial and synthetic dyes. Additionally, Inositol Plus is manufactured under strict procedures to ensure there is no cross-contamination during manufacturing and storage.


What are the benefits of Inositol if I have Polycystic Ovary Syndrome (PCOS)?

Inositol isn't a treatment for PCOS, but research shows that inositol supplementation may be beneficial for some of the symptoms. PCOS symptoms can vary greatly from person to person, ranging from irregular periods to acne, obesity, or excess body hair. If you are experiencing one or more of these common PCOS symptoms, talk to your healthcare provider to see if myo-inositol supplementation is right for you. Inositol supplementation may also help support normal insulin sensitivity and may help support healthy hormone levels.

What are the benefits of Myo-Inositol supplementation for men and women?

In females, Myo-Inositol may support healthy hormone levels and may support egg health, and ovarian health..

For males, Myo-Inositol was shown to support sperm motility in a randomized clinical trial conducted on 37 patients.‡


What are the benefits of D Chiro-Inositol?

A case study shows that D Chiro-Inositol supports healthy hormone levels.

Can an inositol supplement support healthy blood pressure?

Yes, a systematic review and meta-analysis of randomized-controlled trials indicated that inositol supplementation likely supports healthy blood pressure.

The ratio of Myo-Inositol to D Chiro-Inositol in your supplement matters.

Our Inositol Plus dietary supplement is formulated to match your body's natural 40:1 ratio of Myo-Inositol and D-Chiro Inositol, supporting both female and male fertility by promoting healthy ovulation, sperm motility, and egg health.
