Vitamin D, gut health, and your microbiome. What actions must we take today to build ourselves up for a lifetime of undeniable health? How do we know if our diet, supplements, and environment are causing us harm rather than good? On this episode of Health Theory, Dr. Joel Gould joins Tom Bilyeu to address these questions head on and discuss the hidden benefits of Vitamin D that no one seems to be talking about. They reveal the root causes of symptomatic health problems, how your gut is influenced by Vitamin D, the negative impact of the vegan diet, how the key to aging is deuterium, why you should be eating grass-fed, which supplements to take and when, and the ‘must-dos’ to achieving optimal health.
