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.*This episode is also brought to you by Momentous high-quality supplements! Momentous offers high-quality supplements and products across a broad spectrum of categories, and I’ve been testing their products for months now. I’ve been using their magnesium threonate, apigenin, and L-theanine daily, all of which have helped me improve the onset, quality, and duration of my sleep. I’ve also been using Momentous creatine, and while it certainly helps physical performance, including poundage or wattage in sports, I use it primarily for mental performance (short-term memory, etc.).Their products are third-party tested (Informed-Sport and/or NSF certified), so you can trust that what is on the label is in the bottle and nothing else. If you want to try Momentous for yourself, you can use code Tim for 20% off your one-time purchase at LiveMomentous.com/Tim. And not to worry, my non-US friends, Momentous ships internationally and has you covered. *For show notes and past guests on The Tim Ferriss Show, please visit tim.blog/podcast.For deals from sponsors of The Tim Ferriss Show, please visit tim.blog/podcast-sponsorsSign up for Tim’s email newsletter (5-Bullet Friday) at tim.blog/friday.For transcripts of episodes, go to tim.blog/transcripts.Discover Tim’s books: tim.blog/books.Follow Tim:Twitter: twitter.com/tferriss Instagram: instagram.com/timferrissYouTube: youtube.com/timferrissFacebook: facebook.com/timferriss LinkedIn: linkedin.com/in/timferrissPast guests on The Tim Ferriss Show include Jerry Seinfeld,
