We empower women to become experts on their own body through scientific knowledge and understanding

Our Story

We started Forth in 2016 with a simple vision: to help people be healthier by understanding their body’s own biochemistry. Today this is still our core focus, however, as a female-led company I’ve become increasingly frustrated with the shortcomings in women’s health. We were determined to do something about it.

In 2021 we put our words into action with the launch of our revolutionary hormone mapping test, MyFORM®, which is the focus of our first ever TV campaign. From here we press forward with our mission to help close the gender health gap by providing women with deeper scientific insights into their own body. We couldn’t be prouder of our journey so far, or more excited for the future.

Our values

Health equality

We’re putting scientific data into the hands of women so that they better understand their own body. Together we can close the gender health gap.

Our values

Scientifically human

We use scientific evidence combined with a human touch to give women the real-life insights they need to be in the best of health.

Our values

It’s personal

We understand that every woman is unique. So we develop innovative solutions that treat each woman as an individual.

Women’s health is about a lot more than just hormones, just as hormones are about a lot more than fertility.

For way too long, women have been without the resources and knowledge needed for them to be the best version of themselves. Does that sound familiar? At Forth, we’re trying to change that by developing a health ecosystem just for you, with all the support and answers you need to take control of your health. Whether you’re struggling with hormone-related symptoms, are managing a genetic condition or simply looking to improve your nutrition, we’re empowering you like never before.

Did you know that so many women are struggling to get the answers they need when it comes to hormone health? That’s why we developed MyFORM®, a ground-breaking test which maps how a woman’s key hormones fluctuate across the entire length of their menstrual cycle.

We're challenging the gender gap in female healthcare
