Foundational Hormone Support, Everyday
Best-Selling Duo: Inositol Infusion Plus & Magnesium Glycinate
Nutritional Support for Every Phase of Motherhood
Trusted support for fertility, conception, pregnancy & postnatal
Created by a doctor who lives with PCOS
Dr Amina Hersi founded PolyBiotics after experiencing first-hand how poor most supplement options really were — confusing, underdosed, and not made with women like her in mind.
Designed to support your body every day
We believe in consistent, daily support — not quick fixes. From cycle regulation to energy, skin and sleep, our products help you feel more like yourself again.
Clean, filler-free, and genuinely effective
No gimmicks or underdosing. Just well-absorbed, high-quality supplements that do what they’re meant to.

Every formula is rooted in research and reality
These aren’t trendy blends. Every ingredient and dose is backed by clinical evidence and chosen to reflect what actually works for women with hormonal imbalances.
Not just for fertility — for your whole journey
Most brands stop at TTC. We support you from diagnosis, through pregnancy, postpartum and beyond.
Made by a doctor. Trusted by thousands.
These are the products Dr Amina recommends — and takes. Trusted by thousands of women across the UK, and growing every day.
