Decision Guide

How to Use This PCOS Hub

Use this hub to compare supplements studied in PCOS by the target: insulin sensitivity, ovulatory and cycle support, or androgen-related symptoms. The strongest pages are specific about the PCOS phenotype and the outcome studied, and defer to clinical care for diagnosis and medication.

Choose by fit

Match the supplement to the driver: insulin resistance, ovulatory dysfunction, or hyperandrogenism are different targets.
Prefer pages that report the specific outcome (cycle regularity, insulin markers, ovulation) rather than general "hormone balance."
Inositol ratio and berberine dosing details matter; favor pages that state them.

Safety first

Coordinate glucose-lowering supplements with any diabetes or fertility medication under clinician guidance.
Pregnancy, active fertility treatment, and psychiatric medication warrant medical review before stacking supplements.
Do not use supplements as a substitute for PCOS diagnosis and metabolic monitoring.
