OB/GYN · Women's Health Researcher
Researchers tracking 12,000 women found that a specific colony of gut bacteria determines how much estrogen your body absorbs. When these bacteria are disrupted, estrogen recirculates in ways standard bloodwork misses entirely.
Your liver tags estrogen for removal. An enzyme called beta-glucuronidase reverses that tag. And the bacteria producing this enzyme live in your gut. A 2025 review in the International Journal of Cancer mapped the full mechanism for the first time. Read the research →

Deep dives into what matters
Vaginal Health
BV research, probiotics, pH balance, and the microbiome science behind vaginal wellness.
Gut Health
The estrobolome, gut-vaginal axis, and how your digestive system controls hormonal balance.
Hormonal Balance
Cortisol, estrogen metabolism, stress biology, and what actually moves the needle.
Between 20% and 70% of women treated for BV will see symptoms return within six months. Researchers at the University of Maryland finally found the reason, and it has nothing to do with the strength of the antibiotic.
When antibiotics clear the infection, a small group of bacteria survives by attaching to the vaginal wall and building a protective coating. After that, they wait. The new research maps exactly how this works — and what actually breaks the cycle. Read the research →
