The science behind Free Soul
Every Free Soul product is shaped by real women, formulated by clinicians, grounded in published evidence and third-party tested before it reaches you.
"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 · RNutr, BSc, MRes, MSc
Science advisory board
Every product we make is tested, checked and shaped by people who've spent their careers studying women's health properly.

By the numbers
The process
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.
Our nutrition team reviews the published research behind every ingredient: what works, at what dose, in women's bodies. If the evidence is thin, it's out.
Our in-house medical team and expert panel pressure-test every formulation (doses, interactions, life-stage suitability) before anything is made.
Every product is tested by independent labs before release, so what's on the label is what's in the pouch.
Post-launch, products are re-tested, reviewed against new research and reformulated when the science moves.
"We pay for the test, and that's where our input ends. Everything independent, nothing compromised."
Tanith Rixson, Technical Manager at Free Soul, Retail & InnovationEvery active ingredient is supported by published studies, at the doses we actually use.
Trials on Free Soul formulations are in progress, and we'll always publish what we find.
What's on the label is what's in the pouch, verified by labs we don't own.
