FAQ

What makes the 40:1 ratio so special?

Think of it like the “golden ratio” for women’s wellness. Science shows that this exact balance of Myo- and D-Chiro Inositol is the most effective at supporting hormone balance, healthy ovarian function, and metabolic wellness.

How does PQQ fit into the formula?

PQQ is your cell’s personal energizer. While the inositols help balance hormones and support reproductive health, PQQ works on a deeper level: sparking new mitochondria (your cell’s power plants) and boosting energy production for body and mind.

Can this help with fertility support?

Yes! The combination of Myo- & D-Chiro Inositol has been widely studied for supporting ovulation and reproductive health. While everyone’s journey is unique, many women include this blend as part of their fertility wellness routine.

How long before I might notice results?

Consistency is key. Many users begin to notice positive changes in energy, mood, or cycle regularity within 6–8 weeks. But because every body is different, results may take a little longer. Patience + daily use = best outcomes!
