When I was first diagnosed with PCOS, I had questions- lots of them.

Even as a doctor, I couldn’t find the support I needed.

The supplement industry felt overwhelming. So many brands were offering vague “hormone balancing” formulas, filled with trendy ingredients, low doses, or products that just didn’t make sense for the complexity of hormonal conditions like PCOS.

So I created PolyBiotics.

A science-led, physician-formulated supplement brand that combines clinical research, real-world experience, and heartfelt support—for women just like me.

Manage Your PCOS

Meet the Founder: Dr Amina Hersi

I’m a qualified medical doctor, trained at University College London (UCL), with a postgraduate diploma in Obstetrics and Gynaecology, and a PCOS leader and advocate through the University of Birmingham Metabolic Institute.

I created PolyBiotics in 2021, using both my medical background and my personal journey with PCOS to formulate products that are effective, well-tolerated, and rooted in real evidence.

Since then, over 7,000 women have trusted our products to support their hormonal balance, menstrual health, fertility, energy, skin, weight and confidence.

I can't wait to hear how these supplements help you.

With love,

Manage Your PCOS

Why We’re Different

  • Physician-formulated

    Every formula is created by a medical doctor who specialises in PCOS, with ingredient doses based on the latest clinical research.

  • Rooted in lived experience

    I created these products because I needed them. I still take them every day. I understand what it means to live with hormone symptoms.

  • Science-backed, not trend-led

    No unnecessary filler ingredients. Every capsule exists for a reason.

  • High quality

    We only use the most bioavailable forms of each ingredient (like folate instead of folic acid) and all products are vegan, gluten-free, third-party tested and made in the UK.

  • Support from first diagnosis onwards

    Whether you’re trying to conceive, regulating your cycles, managing skin and hair symptoms, or just trying to feel more like yourself—our products and content are here to guide you through every stage.

  • Not just for fertility

    PCOS is about so much more than getting pregnant. We create supplements that support your hormones, mood, metabolism, skin, sleep, and cycle—for life, not just one season of it.

For too long, hormonal health has been treated as an afterthought—especially when you’re not actively trying to conceive.

Whether you’re searching for:

  • PCOS supplements that actually work
  • Natural support for ovulation and cycle regulation
  • Hormone-balancing vitamins and minerals
  • Doctor-formulated alternatives to traditional fertility pills
  • Or simply a brand that gets it...
