Who develops Free Soul products?

Every product is developed by our in-house team, led by our Head of Nutrition, Nat, alongside our product development team. Where relevant, we also bring in specialist input from our wider panel of experts to make sure what we create is grounded in real, current research.

How does scientific research inform Free Soul products?

Before a product is created, we look at the evidence: what the research says about the ingredients, the dosages and how they actually work for women's bodies. That research shapes everything from the formulation to how we talk about it - so nothing is based on trend or guesswork.

Who reviews Free Soul's nutrition and wellness content?

All of our nutrition and wellness content is reviewed by our in-house nutrition team to make sure it's accurate, balanced and backed by evidence - not hype or trends.

Can Free Soul's experts recommend the right supplement for me?

Our experts shape the science behind our products, but they're not able to give personalised medical advice. To find what's right for you, take our quiz - it's built around your individual needs.

How does Free Soul decide which products to create?

We start with a genuine gap: something women need that isn't being met properly, or isn't backed by real evidence elsewhere. From there, our nutrition team and expert panel help shape the product from formulation through to how we talk about it.

Our Science & Credibility Expertise

THE SCIENCE BEHIND FREE SOUL

Women's health, held to a higher standard.

Every Free Soul product is shaped by real women, formulated by clinicians, grounded in published evidence, and third-party tested before it reaches you. This page shows you exactly how.

"Most of the research the supplement industry leans on was never done on women. That's the gap we exist to close - with evidence, not marketing."

Natalie Rouse, Head of Nutrition at Free Soul

Registered Nutritionist (ANutr) BSc MRes MSc

THE STANDARD

Why this page exists.

The supplement industry has a trust problem, and it earned it. Vague promises. Hidden doses buried in "proprietary blends". Research done on men, sold to women.

So here's everything behind ours. The people, the process, the testing, the evidence - including the parts still in progress. No proprietary blends. No hidden doses. No claim we can't show you the source for.

The people who did the research, so you don't have to.

Dr Holly Vaughan

More about Holly's background

Holly holds the British Menopause Society Advanced Certificate in the Principles and Practice of Menopause Care, and trained in lifestyle medicine through the British Society of Lifestyle Medicine. Her focus on hormone health grew out of years spent seeing women struggle with widespread misinformation and fear. She takes a holistic approach, helping women understand their whole health picture so they can take an active role in their health with informed, personalised choices - because the goal isn't just to survive perimenopause and menopause, it's to thrive through them.

The process

From 6,000 women to your cupboard. Every step, shown.

1. It starts with her.
Through Designed By Her, our co-creation platform, insights from over 6,000 women tell us what to build — the real gaps in women's health, not what's trending.
2. The evidence.
Before an ingredient earns a place, our nutrition team reviews the published research behind it: what works, at what dose, in women's bodies. If the evidence is thin, it's out.
3. Clinical review.
Our in-house medical team and expert panel pressure-test every formulation - doses, interactions, life-stage suitability - before anything is made.
4. Third-party testing.
Every product is third-party tested by independent labs before release - so what's on the label is what's in the pouch.
5. It never stops.
Post-launch, products are re-tested, reviewed against new research, and reformulated when the science moves.

Our approach to product innovation.

Backed by published studies.

Every active ingredient we use is supported by published studies - at the doses we actually use, not fairy-dust amounts.

Our own clinical trials - underway now.

We're not waiting to be asked. Product trials on Free Soul formulations are in progress, and we'll always publish what we find.

Independent third-party testing.

What's on the label is what's in the pouch — verified by labs we don't own.

Authorised health claims only.

Every claim we make is an authorised claim under UK regulation. If we can't say it under the rules, we don't say.

Designed by her

6,000+
