Can myo-inositol support healthy blood sugar signaling?

 Myo-inositol is a naturally occurring, sugar-like compound your body already produces and uses as part of normal cell signaling, including the pathway that helps cells respond to insulin. Research on myo-inositol's role in this signaling pathway is part of why it's included in cycle and fertility-focused formulas like Myo Chiro 40:1.

What myo-inositol actually is

According to the Cleveland Clinic, inositol is a sugar your body produces naturally to help build cell structure, and it also plays a role in insulin signaling and certain brain chemical messengers. The National Cancer Institute similarly describes it as a nutrient that helps cells make membranes and respond to messages from their environment.

How inositol relates to insulin signaling

Myo-inositol and its related compound, D-chiro-inositol, act as second messengers in the insulin signaling pathway, meaning they help relay the signal that tells cells to take up glucose. A 2021 review published in Frontiers in Endocrinology described D-chiro-inositol's role in regulating this signaling process in human fat cells, part of a broader body of research into how inositols participate in normal metabolic function.

Insulin itself is a normal part of how the body regulates blood sugar day to day. According to the CDC, insulin signals cells to take up circulating blood sugar and signals the liver to store extra for later use, a finely tuned system that depends on healthy cell signaling.

Where Myo Chiro 40:1 fits

Myo Chiro 40:1 uses a clinically studied 40:1 ratio of Myo-Inositol (2000 mg) to D-Chiro-Inositol (50 mg), formulated to support healthy hormone signaling, ovarian health, and menstrual cycle regularity.† D-Chiro-Inositol specifically supports healthy androgen function and ovarian hormone function.†

• Our 40:1 myo-inositol and D-chiro-inositol blend, supporting healthy hormone signaling and cycle regularity†
• Our fertility gummies with methylated folate and myo-inositol, which also supports healthy insulin signaling and ovarian hormone function as part of a broader preconception nutrient blend†

"Every ingredient we put into our supplements has to earn its place through real science," says Amy Suzanne Upchurch, Founder and CEO of Pink Stork. "That's not in conflict with faith, it's an expression of it."

Frequently asked questions

Is myo-inositol the same as a vitamin?

No. Inositol used to be called vitamin B8, but it's not classified as a true vitamin since the body can produce its own supply.

What's the difference between myo-inositol and D-chiro-inositol?

They're closely related compounds that work together in cell signaling. Research supports a 40:1 ratio of myo-inositol to D-chiro-inositol as reflecting the natural balance found in the body.

Can I take Myo Chiro 40:1 while pregnant?

No. Myo Chiro 40:1 is not for use during pregnancy. It's formulated for women trying to conceive. Talk to your healthcare provider about supplement use during pregnancy.

Does Myo Chiro 40:1 lower blood sugar?

Myo Chiro 40:1 is formulated to support healthy hormone signaling, ovarian health, and menstrual cycle regularity.† It does not make any claim about lowering blood sugar or treating any condition.

How long does it take to notice a difference?

Cycle-related changes are often gradual. Many women track their cycles over a few months to notice patterns while using a supplement like Myo Chiro 40:1.
