Expert-Led, Evidence-Based Supplements
Made by Women, for Women
In a world of Fast Fashion came a world of fast nutrition
Navigating a diagnosis involving two hormonal conditions, even as a doctor, I struggled to find the support I needed.
The supplement industry felt overwhelming. Brands were offering vague formulas, packed with trendy ingredients, promoted by influencers, often at doses that made little sense for the complexity of women’s health.
Supplements were being drop-shipped like leggings — the next big trend.
But where was the science?
Where was the understanding of how women’s bodies actually work?
So I created PolyBiotics.
A science-led, physician-formulated supplement brand that brings together clinical research, real-world experience, and genuine care — for women like me.
Nutrition that isn’t driven by trends, but by evidence.
Slow nutrition — designed to work with your biology, not rush it.
Blends that earn their place in your daily routine, where every ingredient is included for a reason.
Precision. Purpose. PolyBiotics.

Meet the Founder
I’m a qualified medical doctor, trained at University College London (UCL), with a postgraduate diploma in Obstetrics and Gynaecology. I’m also a PCOS leader and advocate through the University of Birmingham Metabolic Institute.
Despite my medical training, navigating life with PCOS and Hashimoto’s (underactive thyroid) has been challenging. Like many women, I found that truly supportive care was hard to come by. Over time, nutrition became an important part of how I looked after my health — not as a quick fix, but as a consistent, considered approach.
I created PolyBiotics in 2021, drawing on both my clinical background and my lived experience. The aim was simple: to formulate supplements that are thoughtfully designed, well tolerated, and grounded in real evidence — without chasing trends or making unrealistic promises.
Since then, over 10,000 women have chosen PolyBiotics as part of their daily routines to support their wellbeing. I’m continually inspired by the community that has grown around the brand, and I’m honoured to be part of so many individual journeys.
I can’t wait to hear about yours.
With love,
