About Me | Marieke Steen

Hi I'm Marieke Steen

I’m a Functional Nutritional Therapy Practitioner and your personal Stress Detective, here to help women in their 40s and beyond get to the root of confusing symptoms like fatigue, bloating, mood swings, hormone shifts, and a general sense of not feeling like yourself anymore.

If you've ever thought, “I don’t recognize this version of me,” you're not alone - and you’re not broken.

I’ve spent years on both sides of the health puzzle: as a woman navigating my own healing journey, and as a clinician helping others do the same. What started as a quest to manage my own chronic symptoms eventually led me deep into the world of root cause medicine and functional testing.

At first, shifting to a whole-food diet made a huge difference - more energy, fewer flare-ups, and a stronger connection to how food impacted my body. But over time, I realized food wasn’t the whole story.

I still felt overwhelmed, inflamed, reactive. I needed to go deeper.

What makes my approach different?

I don’t hand out generic protocols. I investigate.

I listen to your story, look at your labs, and connect the dots between your symptoms and what your body’s trying to tell you.

This isn’t about chasing quick fixes.
It’s about uncovering what’s quietly dysregulating your body and helping you feel safe and in sync again.

Whether you're dealing with weight gain, burnout, bloating, or sleep issues, we’ll use food, data, and daily practices to help you reconnect with your body’s wisdom.

Ready to stop feeling like a stranger in your own body?
Let’s uncover what your symptoms are really saying - and build a roadmap back to balance.
