Buying Guide

Choose the right inositol form

Pick myo‑inositol, d‑chiro inositol, or IP6 based on your goal—myo/d‑chiro blends for hormonal balance and IP6 for immune/mineral support

Check myo:d‑chiro ratio

For women’s hormonal and ovarian support, look for products listing a clear myo‑inositol to d‑chiro‑inositol ratio (common 40:1)

Compare dose per serving

Compare milligrams of active inositol per serving and total servings to judge value and how long a container will last

Inspect additional nutrients

Note added ingredients like folate, vitamin D, or calcium/IP6 which can change the product’s target use and benefits

Prefer transparent labels

Choose brands that list exact inositol forms and amounts rather than proprietary blends for clearer dosing
