Can you really build more muscle just by rethinking how you dose leucine and essential amino acids? Dr. Daniel A. Traylor, Ph.D. — co-founder and principal scientist of LEUVATE™ — reveals the science behind protein quality, muscle protein synthesis, and why older adults may need twice the protein dose to get the same results as younger people. We dig into mTORC1 signaling, sarcopenia, the 30g protein absorption myth, GLP-1 drug effects on muscle, and the clinical trial data behind LEUVATE™. If you care about muscle, longevity, or protein strategy, this one is loaded. Guest Bio Daniel A. Traylor, Ph.D. is an Assistant Professor of Health Sciences at DePaul University in Chicago and Owner, Co-Founder, and Principal Scientist of LEUVATE™. His research explores how protein quality, amino acids, and exercise interact to influence muscle adaptation, recovery, and physical function across the lifespan. He is the co-inventor of LEUVATE™ — a precision-engineered leucine-enriched nutritional formula validated across multiple peer-reviewed human clinical trials.
