The Brain Health Secret Every Man Over 40 Needs to Know 

What does it actually take to repair a damaged gut? Not vague advice - a real, structured protocol you can map onto your own life. 

In this clip from Jonty & The Doc, Dr. Marcus Ranney walks through the 5R Framework for gut repair - a systematic functional medicine protocol - with Jonty applying each step to his own routine in real time. 

The 5Rs: 

Remove — eliminate what's actively harming the gut 

Replace — restore what's been depleted: enzymes, stomach acids 

Reinoculate — reintroduce beneficial bacteria through food and supplementation 

Repair — rebuild and heal the gut lining itself Rest & Recovery— the most underrated step, and the one most of us skip entirely. 

If you've been dealing with IBS, digestive sensitivity, bloating, or just know your gut isn't working the way it should - this framework is your starting point!
