Prevention is everything
The best care starts earlier than you think
There are an overwhelming 500+ known symptoms tied to declining estrogen that can present as early as your mid-thirties. You are the first generation with the scientific support to get ahold of symptoms early, before they get ahold of you. Welcome!
Start early
Declining estrogen can show up years before menopause is on your mind.
Get personal
Your phase or window belongs in the Fluxx Diagnostic, not in a guess from a chart.
Bring evidence
A confidential summary helps your clinician see the pattern and align care.

Fluxx is for women everywhere
As a board certified OB/GYN and menopause specialist who started prescribing hormone therapy in the 1990s, my career has spanned the twenty-year arc of the faulty 2002 Women’s Health Initiative trial, which overnight led to the cessation of treating peri/menopausal women with hormones. Though later proven wrong, it left an entire generation of women without care.
As a doctor, I witnessed the most devastating fallout: wide-sweeping fear and mass confusion we are still correcting today. Disruptive hot flashes, brain fog, anxiety, insomnia, and hundreds of symptoms left untreated, an unhealthy reliance on antidepressants and collateral damage in the form of the loss of identity, marriages, jobs, mental health, and the subsequent rise of disease and mortality.
The most dangerous byproduct of all? Silence. Menopause was taboo, hushed, and wholly ignored by clinicians, educators, scientific studies, and culture. That stops here and now with you and me.
Together, we’re putting your preventive care and well-being first, while leaving a collective legacy of de-identified data, with the mission to advance women’s health globally for generations to come. Thank you for being here.
