Buying Guide

Choose the clinically studied 40:1 ratio

Look for products that provide myo‑inositol and d‑chiro‑inositol in a 40:1 ratio, which is commonly used in clinical research for PCOS

Check total daily dose and servings

Compare per‑serving milligrams and the number of servings per container to calculate the typical therapeutic daily dose and value

Prefer clean formulations

Select supplements with minimal additives, vegan or gluten‑free labels if needed, and transparent ingredient lists to reduce intolerance risk

Opt for powder or capsule based on adherence

Powders allow flexible dosing and mixing, while capsules offer convenience and consistent dosing for daily use

Check brand focus and product intent

Choose brands that explicitly target hormonal balance, fertility, or ovarian support, as they often tailor formulations for PCOS management
