Hi,

I recently took a gut health panel, and it showed I had leaky gut. Not a “little” leaky. Enough that my doctor flagged it immediately. The lining of my intestine had gaps, letting things through that shouldn't be. 

Toxins, undigested food particles, and inflammatory compounds were leaking into my bloodstream and triggering low-grade inflammation I'd been writing off as normal training fatigue.

Here's the thing. I felt fine. That's what makes this tricky. Most athletes with leaky gut don't know they have it. You just notice you're a little more inflamed than you should be. Recovery takes a little longer. Your stomach turns on you mid-race, even though you've practiced your fueling. You get sick more often than your training partners. You chalk it up to volume or stress or bad luck.

It's usually your gut.

Why are athletes more susceptible?

Every time you train hard, blood flow shifts away from your digestive system to your working muscles. That's normal. But over time, especially with heavy carb fueling, fasted training, heat, and dehydration, the lining of your gut weakens. Small gaps open between the cells. Things get through that shouldn't. That's leaky gut, and it quietly undermines everything else you're doing.

What I did about it

SwissRX Gut Defense. It's a targeted gut lining repair formula. Not a probiotic, not a digestive enzyme, not a fiber supplement. This is specifically designed to seal and rebuild the gut wall.

The star ingredient is L-Glutamine at a clinically effective dose. Most supplements underdose it. To get an equivalent dose from capsules, you'd need to swallow 16 pills. 

Gut Defense delivers it in one scoop. It also includes Aloe Vera Extract and Licorice Root to calm inflammation, plus additional ingredients that act like spackle for your gut wall, patching the gaps where toxins are getting through.

I add a scoop to my protein shake every morning. During heavy training blocks, I'll go to two. It's Swiss chocolate flavored and actually tastes good, which matters because I'm not going to take something every day that I dread drinking.

$69.95 for 30 servings (powder). Also available in capsules at $64.95 if you'd rather not do a daily drink.

If you're already using Foundation:

Foundation has the same Gut Defense ingredient stack built into it. So if you're taking Foundation daily, you're already getting the gut repair benefit. Gut Defense is for athletes who want the concentrated gut repair piece on its own, or who want to run a heavier dose during a big training block.

Why this matters for performance:

Your gut is where everything else gets absorbed. Every supplement you take, every macro you eat, every electrolyte you drink. 

If your gut lining is compromised, you're not absorbing what you're paying for. Fix the gut, and everything else works better. Recovery improves. Inflammation drops. Your immune system stops fighting phantom threats. Your race day fueling actually lands the way it's supposed to.
