Could the right form of a single vitamin be the difference between thriving and barely surviving?

In this Part 2 conversation, human biologist and longevity expert Gary Brecka reveals the #1 overlooked factor that’s wrecking your health: methylation—your body’s ability to convert nutrients into fuel. If this process fails, your hormones, energy, and even mental health take a nosedive.

Gary and Dave dive deep into the real cause of anxiety, ADHD, and mood disorders, the hidden genetic reason why diets fail, and why Big Pharma isn’t talking about this critical health breakthrough.

Are you unknowingly setting yourself up for disease? What’s the simple fix that can reverse anxiety, gut problems, and even prevent genetic disease? And why is your doctor ignoring one of the biggest markers of longevity?

What You’ll Learn:

• The MTHFR gene mutation—and why it’s quietly affecting millions

• Anxiety, ADHD, and depression—why these disorders start in your cells, not your brain

• The gut-brain connection—how your microbiome controls your mood

• Why your “healthy diet” might be hurting you (and what to eat instead)

• How nutrient deficiencies are passed from mother to child—and how to stop it

• The truth about homocysteine—the blood marker that could predict your lifespan

• Why most people are living at 50% capacity—and how to get your energy back
