Creatine is one of the most researched supplements in the world, yet it’s still surrounded by confusion, especially when it comes to kidney health and lab interpretation.

In this episode of ReInvent Healthcare, Dr. Ritamarie looks at creatine through a clinical lens. She explains why creatinine levels often rise when someone takes creatine, why that change is frequently misinterpreted as kidney damage, and what labs actually tell us about kidney function.

This conversation also opens a bigger question about supplements: how practitioners can develop real discernment. She is separating myths, marketing, and fear from meaningful science and clinical context.
