Can a plant-derived polysaccharide formula affect Alzheimer’s symptoms? A researcher explains his study, and its limits.

In this episode of Causes or Cures, Dr. Eeks speaks with researcher Dr. John Lewis about his study investigating an aloe polymannose multinutrient supplement in Alzheimer’s disease.

We discuss what polymannose is, why he feels mainstream wellness gets sugar wrong, why the intervention combines multiple nutrients rather than a single compound, and the biological theories behind how it might influence inflammation and immune signaling.

Dr. Lewis also walks through the study design, including the open-label approach, the cognitive and functional outcomes measured, his thoughts on testing against a placebo, and how to interpret mixed results across different tests.

We also talk about the bigger question: what early nutrition studies can suggest — and what they cannot yet prove.

John E. Lewis, Ph.D., is Founder and President of Dr Lewis Nutrition® and a Voluntary Associate Professor at the University of Miami Miller School of Medicine. His research focuses on nutrition, dietary supplementation, and exercise in human health and disease, and he has led or contributed to over 30 studies and more than 180 peer reviewed publications.

Dr. Lewis has presented his work nationally and internationally, mentored students across all levels of training, and delivered a TEDx talk on nutrition and brain health. He is also a Diplomate and Faculty Member of the Medical Wellness Association and continues to promote evidence based approaches to health and wellness.

In this episode of Causes or Cures, Dr. Eeks speaks with neurologist and neuroscientist Dr. Majid Fotuhi about brain aging, memory, intelligence, Alzheimer’s disease, and his new book: The Invincible Brain: The Clinically-Proven Way to Age-Proof Your Brain and Stay Sharp for Life

We explore whether Alzheimer’s is being overdiagnosed and the idea that what we call Alzheimer’s may actually be a mix of different conditions.

Dr. Fotuhi breaks down intelligence beyond IQ, including why IQ tests were originally designed to detect deficits, and how environment can shape cognitive potential. We talk about memory, why we forget names but remember certain details, and he shares fun exercises anyone can do to significantly improve their memory.

We also examine how technology may be affecting the brain, the concept of use it or lose it, and the role of neuroplasticity in shaping brain function over time.

The conversation then turns to prevention. We cover genetics, including the APOE gene, and what you can do to lower your risk, even if you have the high-risk gene. We discuss lifestyle factors such as exercise, sleep, diet, and what having a sense of purpose means for your brain health. We also talk about current treatments, including antibody therapies targeting plaques, and why reducing plaques does not always improve function.

Finally, Dr. Fotuhi shares his approach to building brain reserve and maintaining cognitive health through his Brain Fitness Program.

Dr. Majid Fotuhi is a neurologist and neuroscientist trained at Johns Hopkins University and Harvard Medical School. He serves as an adjunct professor at the Mind Brain Institute at Johns Hopkins and also teaches at George Washington University and Harvard. With nearly four decades of experience in clinical care, research, and teaching, Dr. Fotuhi has developed a multidisciplinary approach to improving brain health and cognitive performance. His Brain Fitness Program combines personalized assessment with targeted lifestyle and cognitive interventions, with results published in peer reviewed journals. He is the author of several books, including Boost Your Brain, and is widely recognized for his work on memory, neuroplasticity, and successful aging, with lectures and media appearances around the world.

Exploring the Spiritual Realm
Where spiritual belief meets health, culture, and skepticism

Disclaimer: This episode discusses spiritual and metaphysical beliefs that are not evidence-based medical treatments. Nothing in this conversation is medical or public health advice. If you have a health concern, please seek care from a licensed clinician. This is entertainment only.

In this episode, Dr. Eeks sits down with Master Nick Eagle, a man whose life has taken a dramatic and unexpected turn.

Before becoming a spiritual teacher, Nick Eagle was Nick Hawk, best known as the star of Gigolos, the Showtime series that followed male escorts in Las Vegas. He built a larger-than-life persona—muscular, confident, and unapologetically masculine. Along the way, he became a Brazilian Jiu-Jitsu black belt, ran a stripper booking agency, wrote for Penthouse, and appeared in outlets like Cosmopolitan and TMZ.

Today, he goes by Master Nick Eagle.

He now leads a very different life...teaching meditation, studying philosophy, practicing yoga, and guiding others through what he describes as spiritual awakening. He runs retreats in Arizona and is the author of The Golden Laws of Enlightenment, a book centered on transcending suffering and connecting to a deeper sense of self.

In this conversation, we explore:

• His transition from nightlife and performance to spirituality and teaching
• How he defines masculinity...then vs. now
• What prompted his personal transformation
• His approach to meditation, Reiki, and Kundalini practices
• The philosophy behind his teachings and retreats
• What it means to “reinvent” your identity

This episode touches on spiritual perspectives that may not align with conventional medical or scientific views. Listeners are encouraged to approach these ideas thoughtfully and seek qualified medical advice when needed.

At its core, this is a conversation about identity, reinvention, and what happens when the life you’ve built no longer feels like your own.
