This episode is brought to you by Rupa Health, InsideTracker, and Cozy Earth.If you’ve ever wondered if supplements are worthwhile or just create expensive urine, this is the podcast episode for you. While I wish it wasn’t the case, I do believe we need supplements to make up for the nutrients we can no longer get through food alone. It’s extra important to note, though, that not all supplements are created equal. And please keep in mind they’re called “supplements” for a reason, not “replacements”—they are meant to supplement a healthy diet and lifestyle to provide the most impact.Today, I’m excited to take a deeper dive into this topic with one of my most trusted sources when it comes to nutrition and dietary research, Chris Kresser. Chris Kresser M.S., L.Ac. is the co-founder of the California Center for Functional Medicine, the founder of Kresser Institute, the host of the top-ranked health podcast Revolution Health Radio, the creator of ChrisKresser.com, and the New York Times best-selling author of The Paleo Cure and Unconventional Medicine. Chris is one of the most respected clinicians and educators in the fields of Functional Medicine and ancestral health and has trained over 2,000 clinicians and health coaches from over 50 countries in his unique approach. He has recently launched Adapt Naturals, a supplement line designed to add back in what the modern world has squeezed out and help people perform and feel their best.This episode is brought to you by Rupa Health, InsideTracker, and Cozy Earth.Rupa Health is a place where Functional Medicine practitioners can access more than 2,000 specialty lab tests from over 20 labs like DUTCH, Vibrant America, Genova, and Great Plains.
