Buying Guide

Check the myo‑ to d‑chiro ratio

Clinical research often uses a 40:1 myo‑inositol to d‑chiro‑inositol ratio for PCOS support, so prefer formulations that disclose that balance

Confirm serving size and total daily dose

Compare how many grams per serving and suggested daily servings to ensure you can reach evidence‑based intake levels without excessive dosing

Look for purity and third‑party testing

Products that list testing or purity standards and avoid unnecessary additives reduce risk of contaminants and undisclosed ingredients

Consider formulation and dietary needs

Choose powders versus capsules, vegan or gluten‑free labels, and added nutrients based on personal digestion, dietary restrictions, and adherence

Evaluate price per serving, not just price tag

Assess value by calculating cost per serving or per therapeutic dose so you can compare options like budget picks under $50 more fairly
