The Chiropractic Roundtable brings together five experienced chiropractors with more than 160 years of combined clinical practice to discuss the future of wellness-centered chiropractic care.

Dr. Jeff is joined by Dr. Kat Kadin, Dr. Jess Buhler, Dr. Maria Cutler, Dr. Carmen Garcia, and Dr. Dondee Nettles for a lively conversation about integrating nutrition, activation science, and lifestyle support into daily practice.

The panel discusses:

• Helping patients maintain their adjustments
• Liquid Collagen and joint health
• Gut health with P84 and Probio
• Protandim NRF2 and oxidative stress
• NAD support and healthy aging
• Why chiropractors often lead the way in whole-person wellness

This episode offers valuable clinical perspectives from doctors who have collectively cared for patients for more than 160 years.

In this episode of Dr. Jeff & Friends, Dr. Jeff welcomes Dr. Brett Brimhall for an in-depth discussion on one of today's most important and often overlooked topics: protecting the brain.

Although many people think about brain health only after memory problems begin, the truth is that our brains are constantly being shaped by stress, nutrition, inflammation, oxidative stress, sleep, physical activity, and the choices we make every day.

Together, Dr. Jeff and Dr. Brimhall discuss:

🧠 How oxidative stress affects the brain throughout life

🧠 The effects of chronic psychological stress and trauma on cognitive function

🧠 Brain health in children, adults, and healthy aging

🧠 Why product combinations—or "stacking" activation protocols—may provide broader support than focusing on a single product

🧠 Strategies to support energy, recovery, resilience, immune function, and long-term metabolic wellness

This conversation explores how activation science, lifestyle, and thoughtful wellness strategies can work together to help protect one of our body's most valuable organs — our brain.

Whether you're interested in optimizing performance today or supporting healthy aging for the future, this episode provides practical insights into protecting your brain for the long term.

What goes into creating a nutritional supplement that is truly backed by science?

On this episode of Dr. Jeff & Friends, I'm joined by Dr. Nancy Bryan, former LifeVantage formulator, scientist, and educator, for a fascinating behind-the-scenes look at how science-based nutritional products are developed.

Rather than simply discussing ingredients, we explore the why behind the formulations and how thoughtful design can influence health, metabolism, and healthy aging.

During our conversation we discuss:

• Dr. Bryan's role in developing LifeVantage's D+ (Vitamin D+), AM/PM Vitamins, and Prebiotic

• Why Vitamin D deficiency remains one of the most common nutritional deficiencies in America—even for people living in sunny climates

• The science behind circadian nutrition and why taking specific nutrients in the morning versus the evening may improve how your body utilizes them

• The importance of trace minerals such as copper, zinc, iodine, selenium, and molybdenum, and the critical roles they play in metabolism, thyroid health, antioxidant defense, and cellular function

• Why balancing nutrients is often more important than simply taking higher doses

• The often-overlooked relationship between prebiotics and probiotics, why they work together, and how supporting your microbiome begins by feeding the beneficial bacteria already living in your gut

If you've ever wondered why some supplements seem thoughtfully designed while others are simply a collection of ingredients, this conversation provides a rare look inside the science of nutritional formulation.

Whether you're interested in healthy aging, metabolism, thyroid health, gut health, or simply making smarter decisions about supplementation, you'll come away with practical insights you can begin applying immediately.

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.

Topics Covered:

• Testosterone
• Erectile Dysfunction
• Men's Health
• Oxidative Stress
• Hormones
• Metabolism
• Relationships
• Pornography and the Brain
• Healthspan vs Lifespan
• Regenerative Medicine
• Longevity

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.
