Vitamin B1: The Carb-Burning Vitamin and Why RDAs Fall Short | Grow or Die S7 E3

Vitamin B1 is central to the way I think about carbohydrates, energy and performance. In this episode, I explain why I distinguish meeting the RDA from the level of health and performance I aim for with my clients.

I walk through thiamine’s role in cellular energy, the relationship between carbohydrate intake and B1 demand, why magnesium matters, and how I use temperature, pulse, recovery and training performance alongside lab work. I also discuss Eminent Nutrition’s Cellular Ignition and my approach to evaluating supplement response.
