Before mapping the movement of hormones. I was treating the mobility of the body.

I’m a Doctor of Physical Therapy.

I started my career working in high-pressure intensive care units with the most medically complex patients.

In my Miami Beach clinic, I spent years treating their pain with my hands.

Identifying their problem areas and helping to restore their function.

And after almost a decade, I learned the one lesson that would eventually build this company.

The pain is almost never where the problem is.

A woman comes in with a screaming shoulder. The cause is her neck. You can treat that shoulder forever and get nowhere. Treat the network, and the shoulder quiets down. In fact, a lot of women suffering with joint pain actually have low estrogen. And when we supported their hormones with supplements, the pain went away.

Once you’ve seen that a hundred times, you can’t unsee it anywhere.

So when women started coming to me ‘wired and tired.’ In pain and PMS-ing. Lost and low energy.

I didn’t see a list of separate complaints. I saw the same thing I’d seen in every body I’d ever treated. A system, out of sync.

Chasing one symptom with one ingredient was never going to work.

But solving the symptoms by supporting the system, that’s what got me really excited.

It’s what inspired me to get advanced training in functional medicine, clinical and chrononutrition, and eventually into a field most people have never heard of.

Network phytopharmacology.

The study of plants, herbs, and botanicals, how they interact with each other with our biology.

Not one compound aimed at one receptor. A network answering a network.

That became the backbone of Vita-Fem™. I call it PhytoSync.

And it worked. My protocols worked. For six years I reviewed urinary hormone and neurotransmitter panels, tracked symptom scores, and watched women get their lives back.

But here’s what I couldn’t solve.

Doing it right meant up to 20+ capsules a day. Sourced from four different brands. At a cost that made women wince. $300+ per month!

They’d feel like themselves, and then quit. Not because it stopped working. But because nobody could swallow a handful of pills forever.

I kept asking the same question: My protocols help the woman in front of me. How do I help the woman I may never meet?

The answer showed up backstage at a stadium in 2024.

I was traveling as part of Shakira’s wellness team. Every venue, every city, the same thing on the catering table: boxes of electrolyte stick packs. Tear, pour, drink, done. Crew members who would never remember a pill, never once missed a stick.

That was it. That was the delivery system.

So I built it.

The natural botanicals I’d trusted for years in practice.

In their most bioavailable forms.

At clinical-grade doses.

In one sachet a day.

I still wear the white coat, because I earned it.

I still read and write research papers for fun.

And I still believe the thing that got me here: a woman shouldn’t need a private practitioner and a countertop full of bottles to feel like herself.

Now she doesn’t have to.
