Most people assume they’re healthy until something breaks. The problem is that dysfunction shows up in your biology years before symptoms appear.

I sat down with Dr. Paul Turek to break down what modern biomarkers actually reveal about your health, performance, and long term disease risk.

We explore why “normal” lab ranges can be misleading, why guessing based on symptoms fails, and how early signs of metabolic dysfunction, inflammation, and nutrient deficiencies quietly shape how you feel, train, and age.

This conversation is about testing and not guessing. We spoke about how to understand what’s happening inside your body before problems become diagnosed. And about taking ownership of your health data at any age, not reacting once it’s too late.
