Episode Overview

This episode dives deep into the often-misunderstood world of cellular health and longevity, challenging the conventional quick-fix approaches dominating health culture today. Dr. Josh Axe welcomes Dylan Gemelli, a veteran in the peptide and cellular medicine space, to discuss why most longevity advice is backwards—focusing on hacks, supplements, and hormones before nutrition, mindset, and spirituality.

Cellular Health: Reversing the Common Approach

• Dr. Axe points out that most people chase longevity backwards by experimenting with peptides, hormones, and trendy supplements without foundational understanding.

• Quote [01:59]:
  “People are chasing longevity … but they’re doing it the wrong way and backwards. They’re trying to manipulate hormones … following advice from friends or influencers … not backed by science.” – Dr. Josh Axe

• Dylan Gemelli agrees, emphasizing “all diseases really start within the cell,” highlighting mitochondria and cellular inflammation as root causes.

• Both stress:

  • Start with food, not supplements (“what are the top 10 magnesium-rich foods?”) [04:31]
  • Supplements are for supplementing, not replacing core nutrition.

Key Nutrient Deficiencies & Personalized Testing

• Most common deficiencies:

  • Vitamin D: Largely due to lack of sunlight, fear of sun [06:55–07:05]
  • Selenium & Iodine: Essential for thyroid, mental clarity. Often overlooked [07:20, 09:53]
  • Others: Magnesium, iron, trace minerals

• Testing Tips:

  • Standard blood work is usually insufficient for root causes [05:42]
  • Timing/supplement status affect results (e.g., avoid supplements for a week before tests) [09:01]
  • Need for functional medicine testing for vitamins, minerals, and toxins

• Toxicity:

  • High levels of mercury, lead, aluminum can cause mood/health issues [12:13]
  • Hidden toxicity impacts both physiological and emotional health
  • “Bad attitude... a lot of times it’s because we have so much toxicity inside and have no clue.” – Dylan [12:13]

The Overlooked Pillars: Mind, Spirit & Emotional Healing

• Dr. Axe:

  • Emotional/spiritual health may be even more critical than nutrition [13:46]
  • Childhood trauma, shame, ongoing stress “elevate cortisol” and wreck the body

• Dylan’s Hierarchy:

  • Spirituality → Mind → Body
  • “I can fix your diet and work you out all day long, but if you’re stressed and you’re mentally off and you’re suffering inside, you’re never going to feel right.” [14:00]
  • Prayer and gratitude are central; “Vitamin G” (gratitude) is “the one thing that everybody’s lacking” [17:31]

• Healing from Hardship:

  • Both share personal/family stories of transformation via perspective, prayer, gratitude, and faith [20:25–25:51]
  • “If you’re living with unforgiveness … it’s as bad as a parasite. It’s worse.” – Dr. Axe [22:41]

• Accountability:

  • Owning one’s mistakes and moving beyond shame is “the lost art” and a foundation of true change

Cell Science Deep Dive

• Dr. Axe & Dylan discuss the structure of the cell and importance of:

  • The Mitochondria: Energy (ATP) production, central to all function and disease [27:46]
  • The Cell Membrane: Recent research emphasizes healthy, flexible membranes for oxygen/nutrient transfer, and protection against disease [28:04–31:38]

• Budwig Protocol & Membrane Health:

  • Focus on omega-3s, quality fats, and phospholipids (from salmon, egg yolks, etc.)
  • Cell membranes are mostly fat and peptides; without healthy membranes, cells can’t breathe or heal [30:35]
  • Cancer, hormone synthesis, vitamin D all depend on healthy fat intake and membrane structure [35:49–36:54]

Fats & The Cell Membrane: Dispelling Diet Myths

• Dr. Axe & Dylan both discuss the damaging effects of low-fat diets:

  • Dylan’s history of severe fat restriction led to “starving, angry, unfocused, miserable” living despite looking healthy [31:38–35:49]
  • Reintroducing healthy fats (avocado, whole eggs, grass-fed butter/meats) led to dramatic improvements in mood, leanness, and well-being
  • “I haven’t been this lean or this full of energy and skin and everything better since I was probably in high school.” – Dylan [35:39–36:15]
  • Emphasizes fat’s central role in membrane integrity, hormones, and overall health

• Key quote [36:15]:
  “People don’t understand how cholesterol is so critically important. 25% of your brain is cholesterol.” – Dr. Axe

Practical Peptide Primer

• What Are Peptides?

  • Short chains of amino acids, “just amino acids in chains” (Dylan) [60:34]
  • Support cell communication, regeneration, hormone signaling
  • Not synthetic hormones—peptides “support” rather than “force” function, reducing side effect risks [61:16]
  • Many peptides are originally derived from animal organs and glands

• Responsible Use:

  • Most peptides should be used in cycles (e.g., 8–12 weeks on/off), not chronically [57:01]
  • Overuse can cause plateau/ineffectiveness and possibly side effects; "it’s a marathon, not a sprint" [58:44]

Peptides for Healing, Longevity & More

Categories Discussed:

• Muscle Building:

  • GHRP6 (stimulates appetite & growth), Tessamorelin (builds muscle/loses fat), Ipamorelin/CJC 1295 (promote growth hormone) [55:45–56:40]

• Healing (Chronic Pain, Injury, Regeneration):

  • BPC157, TB500 (tissue repair, healing, especially for serious injury)
  • KPV (gut and inflammation), GHKCU (skin, collagen)

• Gut Health:

  • BPC157, KPV, oral administration for leaky gut [65:31]

• Mitochondrial Health:

  • Mots-C (“exercise mimetic”, mitochondrial support), SS31 (improves ejection fraction, heart health) [62:52–63:27]

• Mood & Focus:

  • Selank, Semax (anxiety, sharpness, cognition) [61:47]

• Sleep & Longevity:

  • Epitalon (regulates circadian rhythm), short duration dosing cycles [63:27–63:48]

Cautions: The Peptide Industry, GLP-1s & Safe Practice

• Peptide clinics (esp. GLP-1s) are putting profit over health—patients kept on long cycles for financial reasons, not medical logic (Dr. Axe & Dylan) [69:09–71:36]
• Chronic overuse associated with:
  • Regain of lost weight (and more) as soon as cycle ends
  • Net muscle loss, regain as fat, hormone disruption, appetite dysregulation
  • Quote [71:55]: “Whether it’s lack of care or knowledge, it’s bad both ways.” – Dylan

Top 5 Longevity Strategies—In Order [72:52–76:04]

1. Rest & Recovery: Sleep, Sabbath, stress management is “the gift” to treasure
2. Mental/Spiritual Practice: Prayer, gratitude, meditation, time alone with God—a full hour with mindfulness or prayer daily
3. Daily Movement (especially walking): Gentle, consistent, foundational (“Jesus walked everywhere”) [73:36]
4. Consistent, Adaptable Diet: Not perfection, but long-term consistency and adapting diet as you age
5. Regular Bloodwork/Monitoring: Twice a year minimum, track nutrients, hormone levels, and toxicity for prevention
