From Watercress to Holland & Barrett: The Prof&Doc Journey

From Watercress to Holland & Barrett: The Prof&Doc Journey

By Dr Kyle Stewart, Co-Founder of Prof&Doc

There are moments in business that make you stop, reflect, and appreciate just how far you've come. Seeing the Prof&Doc range become available through Holland & Barrett's online store is one of those moments for me.

It's an exciting milestone, not just because Holland & Barrett is one of the UK's most recognised health and wellness retailers, but because it represents another step in our mission to make effective, natural extract, science-led care accessible to more people. To understand why this matters so much to us, it's worth going back to where the story began.

A Passion for Prevention

As a practising doctor, I have spent years helping patients manage illness, but I've always been equally passionate about preventing health problems before they start.

Time and time again, I saw people looking for ways to improve their health, energy and wellbeing through better lifestyle choices, yet many were overwhelmed by conflicting information and an ever-growing selection of supplements. I felt there was an opportunity to bridge the gap between medical science and nutritional support by creating products people could trust.

That belief became the foundation of Prof&Doc.

From day one, our goal has been simple: to develop evidence-based health products that combine scientific credibility with high-quality natural ingredients. Both Professor Paul Winyard (my co-founder) and I wanted every product carrying the Prof&Doc name to be something we would confidently recommend to our own family, friends and patients.

Discovering the Power of Watercress

One ingredient quickly captured our attention: watercress.

At first glance, watercress is easy to overlook. It doesn't have the marketing appeal of exotic superfoods from distant corners of the globe. Yet when we began exploring the science behind it, we were genuinely impressed.

Watercress is widely recognised as one of the most nutrient-dense vegetables available, naturally containing vitamins, minerals and plant compounds that contribute to a healthy diet. Despite its humble appearance, it delivers an impressive nutritional profile that has attracted growing interest from both nutritionists and researchers.

What fascinated us most was that watercress is a truly British success story. Grown locally and sustainably, it offers all the benefits we look for in a modern health ingredient: quality, traceability, nutritional value and an increasing body of scientific interest.

In many ways, watercress perfectly reflects what Prof&Doc stands for. Rather than chasing the latest wellness trend, we wanted to harness the potential of an ingredient that has quietly supported healthy diets for generations. Sometimes the most powerful nutritional ingredients aren't the newest discoveries—they're the ones that have been hiding in plain sight all along.

Building the Prof&Doc Range

The development of our product range has always been driven by one central question:

"Would we be happy recommending this to someone we care about?"

If the answer wasn't an immediate yes, we went back to the drawing board.

We focused on creating products that support people in their everyday health journeys, using carefully selected ingredients backed by both tradition and scientific understanding. Every product represents countless hours of research, formulation and refinement.

As a healthcare professional, I believe trust must be earned. That's why transparency, quality and evidence remain at the heart of everything we do.

Why Holland & Barrett Matters

When many people think about health and wellness retail in the UK, Holland & Barrett is one of the first names that comes to mind.

For decades, it has been a destination for consumers actively seeking products that support their health and wellbeing. That's what makes being listed on their online store such an important achievement for Prof&Doc.

For us, this is about far more than simply adding another sales channel. It's about introducing our products and the benefits of nutrient-rich ingredients, such as watercress, to a wider audience and making them available in a place where consumers already go when they are looking to invest in their health.

It also provides an additional layer of trust and visibility for the brand. When a respected retailer chooses to stock your products, it reflects confidence in your quality, your standards and your potential.

Looking Ahead

While we're proud of how far we've come, we're even more excited about where we're going.

The health and wellness industry continues to evolve, and so does our understanding of how nutrition can support overall wellbeing. We remain committed to researching innovative ingredients, maintaining the highest product standards and helping people make informed choices about their health.

The launch with Holland & Barrett is an important milestone, but it's certainly not the end of the story. In many ways, it feels like the beginning of an exciting new chapter.

To everyone who has supported Prof&Doc so far, our customers, partners, healthcare professionals and supporters, thank you. Your trust inspires us every day.
