Dear Apothecary Myo Inositol is a clean, correctly dosed option. Here is our honest assessment.
What myo-inositol is and why people take it
Inositol is a compound involved in how cells respond to insulin and in hormonal signaling. Myo-inositol, the most studied form, is used for metabolic support and is popular among women managing PCOS, where research is reasonably encouraging.
It is a supportive supplement rather than a treatment, and it is best used with medical guidance for a condition like PCOS.
