How do I choose safe adjunctive products for PCOS?

Shelf order follows evidence and population-fit together: inositol leads (the condition's best supplement evidence — at its trial dose and ratio, which the tag carries), berberine carries its small-trial story with the full interaction weight (this audience is on metformin and contraceptives), and omega-3 closes as the modest, safe, long-game adjunct. All three sit alongside the spine — lifestyle first, prescription therapy by goal, and the fertility team when pregnancy is the plan. The products below are educational examples — not medical recommendations.

The best-evidenced supplement in PCOS: RCTs at ~4 g myo-inositol (with the 40:1 D-chiro ratio) improved ovulation rates, cycle regularity, and insulin measures — with a pregnancy-supporting trial record. Gentle, water-soluble, well tolerated (mild GI at initiation). ⚠️ The ratio is the product: the ovary's own physiology uses 40:1, and the trials tested it — check the label math on any 'PCOS blend.' Anyone trying to conceive should run this through their fertility team — adjunct to letrozole-era care, never a replacement.
