#705: Dr. Willoughby Britton — The Hidden Risks of Meditation, Overlaps with Psychedelic Risks, Harm Reduction Strategies, How to Choose a Retreat, Near-Death Experiences, and More

The Tim Ferriss Show

Tim Ferriss is a self-experimenter and bestselling author, best known for The 4-Hour Workweek, which has been translated into 40+ languages. Newsweek calls him "the world's best human guinea pig," and The New York Times calls him "a cross between Jack Welch and a Buddhist monk." In this show, he deconstructs world-class performers from eclectic areas (investing, chess, pro sports, etc.), digging deep to find the tools, tactics, and tricks that listeners can use.

That is a problem because the body can’t produce omega-3s, an important nutrient for cell structure and function. Nordic Naturals solves that problem with their doctor-recommended Ultimate Omega fish-oil formula for heart health, brain function, immune support, and more. Ultimate Omega is made exclusively from 100% wild-caught sardines and anchovies. It’s incredibly pure and fresh with no fishy aftertaste. All Nordic Naturals’ fish-oil products are offered in the triglyceride molecular form—the form naturally found in fish, and the form your body most easily absorbs.<a href="https://www.nordic.com/products/ultimate-omega/" rel="noopener noreferrer" target="_blank">Go to Nordic.com and discover why Nordic Naturals is the #1-selling omega-3 brand in the U.S. Use promo code TIM for 20% off your order.</a>*This episode is also brought to you by <a href="http://livemomentous.com/Tim" rel="noopener noreferrer" target="_blank">Momentous</a> 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.
