Dr.Jeff & Friends

In this episode of Dr. Jeff & Friends, we pull back the curtain on the fascinating process of developing a health and wellness product—from the initial idea to the final clinical study. Joining Dr. Jeff are two leaders in scientific innovation: Lisa Barnes, Vice President of Research & Development Christina Beers, PhD and Senior Research Scientist Together, they take us behind the scenes of product development and reveal what it really takes to bring a new product to market. In this episode, we discuss: ✅ Where new product ideas come from ✅ The research process behind ingredient selection ✅ How formulations are developed and refined ✅ Bench-top testing and pre-clinical evaluation ✅ The role of human clinical studies ✅ Why scientific validation matters ✅ How new products are evaluated alongside existing products for synergy and effectiveness ✅ What separates evidence-based innovation from marketing hype Most consumers only see the finished product. What they don't see are the years of research, testing, validation, and scientific scrutiny that occur before a product ever reaches the marketplace. This conversation provides a rare look inside the world of product development and offers valuable insight into how science, innovation, and curiosity work together to create meaningful advances in health and wellness. Because every breakthrough starts with a question. And every innovation begins with the courage to ask a better one.

In this episode of Dr. Jeff & Friends, Dr. Jeff sits down with orthopedic surgeon and men's health specialist Dr. Jack Rocco to discuss one of the biggest health challenges facing men today. Over the past 50 years, men's health has changed dramatically. Conditions that were once common in men in their 60s and 70s—such as low testosterone, erectile dysfunction, and metabolic dysfunction—are now being seen in men in their 20s, 30s, and 40s. Together, Dr. Jeff and Dr. Rocco explore: ✅ Why testosterone levels are declining in younger men ✅ The rise of erectile dysfunction at younger ages ✅ How modern diets, obesity, and oxidative stress affect hormones ✅ The impact of pornography and instant access technology on the developing brain ✅ How these issues affect marriages, relationships, confidence, and quality of life ✅ The growing gap between lifespan and healthspan ✅ Hormone replacement therapy, metabolic optimization, and regenerative medicine solutions This is an honest and thought-provoking conversation about what is happening to men today, why it matters, and what can be done about it. Because men's health is about much more than testosterone. It's about energy, vitality, confidence, relationships, and living a longer, healthier life.

This week on Dr. Jeff & Friends: Join my good friend and colleague Dr. Dondi Nettles — one of the most respected voices in LifeVantage, with more than 17 years of experience — as we discuss how the world, our environment, and our health have dramatically changed over the last 50 years, and why controlling oxidative stress with Protandim NRF2 may be more important today than ever before.

This is NOT another health podcast. In this first episode of Dr. Jeff & Friends, we bring together four experts from the LifeVantage Scientific Advisory Board to answer two simple—but powerful—questions: 👉 What made you say YES? 👉 And what's keeping you here today? What unfolds is something much bigger… A pattern. A shift. A realization that what most people have been told about health, weight loss, and metabolism… isn't working anymore. In this episode, we break down: • Why metabolism slows down (even when you're "doing everything right") • The real reason diets fail • What happens when you stop treating symptoms and start addressing root causes • How activation science is changing the conversation around health Featuring insights from: Dr. Jessica Buhler Dr. Maria Liu Dr. Joe Lui Dr. Nancy Ciccarelli Bryan Dr. Jeff's Truth: You don't have a weight problem. You don't have a hormone problem. 👉 You have a SYSTEM problem. And when you fix the system… 👉 everything changes. Follow along weekly as we challenge the system, question the narrative, and take control of our health.
