SwissRX Gut Defense

Every hard training session pulls blood away from your gut and toward your working muscles. Do that repeatedly — especially while fueling with gels and sugary drinks — and your intestinal lining breaks down. Tiny gaps form, toxins leak in, and the bloating and cramping starts. That's not a weak stomach. That's a compromised gut lining.

SwissRX Gut Defense is the gut repair supplement trusted by pro cycling's medical staff — built to seal those gaps and get your digestion back on track.

Clinical L-Glutamine Dose — Not the Watered-Down Version Most L-Glutamine supplements underdose. Gut Defense delivers a clinically effective 4g of L-Glutamine — the amino acid that acts like spackle for your intestinal lining, patching leaky areas and dialing down inflammation where it starts.

A Full Repair Stack, Not Just One Ingredient L-Glutamine is the anchor, but it doesn't work alone. N-acetyl D-glucosamine fills the gaps between mucosal cells. Aloe Vera Extract soothes irritated tissue. DGL Licorice Root protects your intestinal lining and supports healthy bacterial balance. Zinc and Vitamin A shore up immune function and keep your mucosal membranes intact.

Swiss Chocolate Flavor That Actually Tastes Good This isn't a "hold your nose and chug it" supplement. Mix one scoop into milk or water and you've got a chocolate shake that most athletes genuinely look forward to. Easy to take daily — which means you'll actually take it daily.

Your gut lining is one cell thick. L-Glutamine is the primary fuel source for those cells — it rebuilds what hard training breaks down. The supporting ingredients handle inflammation and reinforce the mucosal barrier so the lining stays intact through heavy blocks, race prep, and travel.

How to Use SwissRX Gut Defense

Daily use: Mix 1 scoop (6.4g) into 8–10oz of water or milk, once daily. Evening after dinner works well, it repairs while you recover overnight. 

During hard blocks or travel: Use daily without skipping. These are the windows when your gut is most vulnerable.

Pro tip: Pair with Promix Debloat in the morning for 24-hour coverage — Debloat rebalances your microbiome while Gut Defense rebuilds the lining.

Dr. Kevin Sprouse, Head of Medicine for EF Education-EasyPost Pro Cycling, calls this the single most effective supplement he's encountered from The Feed and now recommends it to all of his patients. Athletes who use it consistently report the bloating and cramping that used to derail their long rides and runs simply stopping.

Think of it as Teflon coating for your GI tract, so nothing leaks through that shouldn't.
