DR. GUNDRY PODCAST: GUT HEALTH, WEIGHT LOSS, AND NUTRITION

What if a 30-second morning habit could lower your blood pressure — no pill, no diet overhaul? In this episode, I'll reveal an ancient trick modern science just confirmed, and why the “minty fresh” mouthwash in your cabinet may be quietly driving your blood pressure up.
Highlights:
The nitric oxide connection — the Nobel Prize-winning molecule that dilates your blood vessels, and why it fades with age
Why mouthwash backfires — killing “99% of bacteria” wipes out the good bugs that lower your blood pressure, by up to 7–10 points
Leaky mouth = leaky heart — how oral bacteria reach your heart valves (from a former cardiac surgeon)
The 30-second fix — scrape your tongue, skip the mouthwash, floss every other day

Topics covered: nitric oxide and blood pressure, the oral microbiome, eNOS and aging, why mouthwash raises blood pressure, dietary nitrates, tongue scraping benefits, leaky gut, leaky mouth, gingivitis and heart health, oral bacteria and heart valves, flossing and C-reactive protein (HS-CRP), inflammation, gut buddies, lectins and gluten, leaky gut and hair loss in women, and natural blood pressure support.

I'll bet you've never heard the word sarcopenia — but I promise you, it's happening to you right now. Starting around age 30, you begin quietly losing muscle mass, and here's the scary part: most of my patients never feel it happening until it's robbed them of the last 20 good years of their life. So today, I want to let you in on something I've learned after seeing patients six days a week for over 25 years: this kind of muscle loss is NOT a normal part of aging. I can prevent it, and so can you — at any age.
In this episode, I break down what I call the gut-muscle axis — how a leaky gut, beaten up by lectins, NSAIDs, and antibiotics, shrinks your protein-absorbing surface area from the size of a tennis court down to a ping-pong table. That's why I tell my patients the problem isn't that you need more protein as you get older. It's that you can't absorb the protein you're already eating. I'll also explain why I think of your muscles as the "customers" that insulin has to sell to, why 88% of overweight folks (and 50% of normal-weight folks) are insulin resistant, and why I'm so concerned about GLP-1 drugs like Ozempic — because up to 40% of the weight you lose on them is muscle, the one tissue you cannot afford to give up.
Plus, I'll show you how sealing your leaky gut blocks myostatins (the little compounds that keep your muscles from growing), why the real money is in your butt and thighs — not your "guns" — and the two free, do-it-at-home strength moves my old friend Jack LaLanne swore by, which you can knock out while you're brushing your teeth. Here's my take-home message, and I mean it: it is never too late to seal your gut and rebuild the muscle that matters most.
What I cover: sarcopenia, muscle loss and aging, leaky gut, gut health, insulin resistance, GLP-1 and Ozempic side effects, protein absorption, the gut-muscle axis, myostatin, strength training after 60, metabolic flexibility, frailty, healthspan, and longevity.

Are we focusing on the wrong thing when it comes to protein and healthy aging?
In this episode, I break down fascinating new research from my friend Dr. Valter Longo that could change the way you think about protein, muscle, and longevity. The key may not be how many grams of protein you eat, but how much of one specific amino acid, methionine, you're getting.
I explain what the study found, why too much or too little methionine may matter, and how mTOR, IGF-1, GLP-1, and gut health fit into the picture. I’ll also share why I don't believe getting older automatically means you need to pile more animal protein onto your plate, and the protein sources I prefer for supporting strength while keeping longevity in mind.
If you're over 50 or 60, eating a high-protein diet, or simply want to stay strong as you age, this is a conversation you don't want to miss.

I explain why high-quality formulas can cost more than what you’d find on a drugstore shelf, and walk you through specific ways to lower what you pay—including a subscription option that can save you up to 60% on certain products, plus a free My Account option that gives you more control over your orders and access to member-only pricing.
I also share a real example from my own patients about what can happen when you stop taking a formula that’s working—and why staying consistent can matter just as much as finding the right product in the first place.
Whether you’re new to Gundry MD or you’ve been taking a formula for years, I’ll give you a simple checklist to help make sure you’re getting the best deal available.
