Is a Vegan Diet Right
for Your Body?
Find out with data-backed insights from the vegan experiment at Function Health.
We’re exploring the idea of a Vegan Experiment—a potential study to compare lab markers between vegans and non-vegans. No judgment or dogma, just real numbers. If there’s enough interest, we’ll take a closer look at how diet impacts key health indicators like methymalonic acid, iron, and advanced cholesterol markers. Whether you’re fully plant-based or just curious, this could provide valuable insights into the effects of different diets on health.
