Samphire exists to unlock brain-based innovation that fits seamlessly into women's lives.
We're on a mission to transform women’s health by providing non-hormonal and non-drug based solutions for real and lasting relief.
Closing the gender gap in brain and cycle health.
Women deserve more than assumptions. They deserve evidence and solutions.
For too long, the health of women and people with menstrual and hormonal cycles, has been understudied, underfunded, and misunderstood. Pain, hormones, mood, and cognitive shifts are still too often overlooked.
Until the 1990s, most clinical trials excluded the female body altogether. Although progress has been made, exclusion still persists in today’s research, tools, and care.
Our mission exists to change that. With brain-based science, clinical technology, and considered design, we've created tools that meet the reality of cyclical bodies. Giving you solutions that work and better support, in every phase of your cycle.
90%
of women experience premenstrual symptoms.
53%
have missed work because of their cycle.
25%
More of women's lives are spent in poor health compared to men.
1%
of global health research funding goes to non-cancerous women's health conditions.
"Women shouldn't need to solve their health problems at the expense of creating new ones. Yet, we've done that for years."
"Through research, innovation, and a dedication to understanding the unique female brain, we're offering solutions that are effective, safe, and tailored specifically to women."
