Mads Tærsbøl is one of Europe’s fastest runners and currently training for the Olympics. He is a dedicated elite athlete and he is always looking to fine-tune anything that can optimize his game. As there were no indicators of toxicity issues, we skipped this step, although we did look at markers for cell health i.e. cell charge (sodium-potassium pump, which is not really a pump, but save that for another day) and minerals as they relate to toxic load. Everything looked in range, so we decided to test for nutrient markers to ensure he is meeting his above-average dietary needs for peak performance. In these times where our soil is so depleted and there is a constant battle in the media about strict vegan vs. meat-and-more-meat philosophies, it becomes evident that we should simply test and not guess, when it comes to health matters and dietary needs for our bodies.
