The Collagen & Fasting Protocol That Resets Your Gut in 21 Days | Dr. Kellyann Petrucci  @drjoshaxe
Uploaded August 2026 | Updated September 2026, 2 weeks ago
Your gut lining is thinner than you think — and that single fact may explain your skin issues, hormonal chaos, and stubborn inflammation. Dr. Kellyann Petrucci, known as the Queen of Bone Broth, joins Dr. Axe to walk through the food-based protocols she has used with patients for 30 years to heal the gut, support collagen, and ease menopause symptoms naturally.

In this episode:
- Why bone broth and collagen directly repair the gut lining — and which amino acids (glycine, proline, hydroxyproline) are doing the work
- The counterintuitive reason raw vegetables can make gut problems worse, and what to eat instead when your digestion is already compromised
- How the HPA axis drives hot flashes and what cortisol management actually looks like in a menopause protocol
- Why blood sugar is almost always the upstream problem behind heart risk — and how metabolic flexibility through bone broth fasting addresses the root cause
- The case for a “mono diet” during acute gut distress, drawn from Dr. Kellyann’s clinical experience and her time studying at a Swiss healing clinic
- How spirituality, gratitude, and reducing chronic stress affect cellular healing — and why Dr. Kellyann considers this non-negotiable in practice
