This episode is brought to you by Athletic Greens. I get asked all the time, “If you could use only one supplement, what would it be?” My answer is usually AG1 by Athletic Greens, 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 AG further covers my bases with vitamins, minerals, and whole-food-sourced micronutrients that support gut health and the immune system.

Right now, Athletic Greens is offering you their Vitamin D Liquid Formula free with your first subscription purchase—a vital nutrient for a strong immune system and strong bones. Visit AthleticGreens.com/Tim to claim this special offer today and receive the free Vitamin D Liquid Formula (and five free 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 all-in-one daily greens product.

This episode is also brought to you by Allform! If you’ve been listening to the podcast for a while, you’ve probably heard me talk about Helix Sleep mattresses, which I’ve been using since 2017. They also launched a company called Allform that makes premium, customizable sofas and chairs shipped right to your door—at a fraction of the cost of traditional stores. You can pick your fabric (and they’re all spill, stain, and scratch resistant), the sofa color, the color of the legs, and the sofa size and shape to make sure it’s perfect for you and your home.

Allform arrives in just 3–7 days, and you can assemble it yourself in a few minutes—no tools needed. To find your perfect sofa and receive 20% off all orders, check out Allform.com/Tim.
