About Femme Fortified

The science of women's energy, translated.

Iron. Hormones. Creatine. Sleep. Every Tuesday, I break down the research on what actually fuels women's energy.

Isabelle Feldhaus

Hi, I'm Isabelle.

I started Femme Fortified because my doctor kept telling me everything looked fine.

Sitting in my doctor's office, exhausted, pain in my hands, inexplicable heart palpitations, only to be told my bloodwork was “normal” and “keep a journal of your symptoms.” I didn't understand how it could be possible. I certainly did not feel normal. And now, I felt crazy.

My training started in biology, where I learned to read the science directly. From there, I spent over a decade in global health, focused specifically on women's health: building health systems, working on policy, and studying the gap between what the published research shows and what women are actually told when they walk into a doctor's office.

An MS in Public Health and a PhD in Population Health Sciences are the research training layered on top of that experience. This training gave me the skills to go straight to the peer-reviewed literature, straight to the sources of the science, read it critically, and translate it into something useful.

Femme Fortified is where all of that meets. The biology. The research methods. The years spent paying attention to how the system actually treats women's health. This is where I put it to work for you.

Why this newsletter exists

I walked out of that office feeling like I had to find the answers myself. My training gave me a way in: straight to the published scientific research, where I did find some answers. Sitting in journals most women will never open.

Nobody was connecting the dots between the science and the questions women are actually asking about their own health. I couldn't be the only one looking for answers.

That's why Femme Fortified exists. The questions I cover are the ones I'm actually asking, because I want the answers for my own life. Every week I go into the published research, break down what I find, and translate it into something you can actually use.
