This episode is brought to you by AG1! I get asked all the time, “If you could use only one supplement, what would it be?” My answer is usually AG1, my all-in-one nutritional insurance. I recommended it in The 4-Hour Body in 2010 and did not get paid to do so. I do my best with nutrient-dense meals, of course, but AG1 further covers my bases with vitamins, minerals, and whole-food-sourced micronutrients that support gut health and the immune system. 

Right now, you’ll get a 1-year supply of Vitamin D free with your first subscription purchase—a vital nutrient for a strong immune system and strong bones. Visit DrinkAG1.com/Tim to claim this special offer today and receive your 1-year supply of Vitamin D (and 5 free AG1 travel packs) with your first subscription purchase! That’s up to a one-year supply of Vitamin D as added value when you try their delicious and comprehensive daily, foundational nutrition supplement that supports whole-body health.
