What if the key to reversing Alzheimer’s isn’t a drug but a simple plant compound hiding in plain sight? In this episode, I sit down with Dr. John E. Lewis, a researcher whose groundbreaking work may revolutionize the way we approach Alzheimer’s. We explore the science of polysaccharides, potent plant-based compounds found in aloe vera and rice bran, and explore how they support the immune system, reduce inflammation, and enhance brain function.

Dr. Lewis shares how his clinical trial showed remarkable cognitive improvements in moderate to severe Alzheimer’s patients–results that stunned even the medical community. We discuss the mechanisms behind these improvements, the immune-modulating power of plant polysaccharides, and how they interact with the gut-brain axis to promote healing.

You’ll also hear how his supplement, Daily Brain Care, was born from this research, the unique ingredients it contains, and why nutrition could be the missing link in Alzheimer’s prevention and care.

“As you know, you cannot supplement your way to good health. Even with Daily Brain Care and possibly a few other supplements, you still need to eat well and exercise every day. You need to stay hydrated, get enough sleep, and manage your stress. Of course, don't use tobacco, and limit your amount of alcohol.”
