EP327: The Missing & Overlooked Longevity Nutrient with Dr. Joel Brind

About this episode

Dr. Joel Brind discusses the importance of glycine as a missing nutrient for health and longevity.

IN THIS EPISODE What if there was a rampant nutrient deficiency accelerating your aging, cranking up inflammation, and quietly sabotaging your health? Not a vitamin, or mineral, but a "nonessential" amino acid that was once abundant in our diets, but is largely missing today. This isn't some fringe theory—it's what new research has been showing about an amino acid called glycine, a missing link to metabolic health, deeper sleep, stronger joints, calmer mood, smoother skin, and even a longer life. That's why we invited Dr. Joel Brind—biochemist, longtime researcher, and author of The Glycine Miracle—onto the Optimize Paleo Podcast. For decades, Dr. Brind has studied amino acids and uncovered surprising truths about protein. We often hear that more protein is always better—but the type of protein also matters and in this conversation, we dig into the science of glycine's profound benefits (especially for inflammation), the myths, and the practical ways to close the "glycine gap" for better health at any age. Listen in and tag someone in the comments who you think could benefit from this important information. VALUABLE RESOURCES Paleovalley Bone Broth Powder >>> Support your body's…
