Product Description

You've done the repair work. Now keep it. SwissRX Gut Defense Capsules are built for athletes who've addressed their gut issues and want a daily protocol that's easy to sustain — no mixing, no scoops, just two capsules three times a day and your gut lining stays protected through whatever training throws at it.

SwissRX Gut Defense Capsules are the maintenance form of the gut repair protocol trusted by pro cycling's medical staff — a full-spectrum formula that keeps your intestinal barrier sealed and your digestion running clean.

L-Glutamine + NAG — The Gut Repair Core L-Glutamine is the primary fuel for the cells lining your intestinal wall. Paired with N-acetyl D-glucosamine, it patches the gaps that form when blood flow shifts away from your gut during hard training — the same mechanism behind bloating, cramping, and GI issues that derail long efforts.

Liver and Antioxidant Support Built In Silymarin (Milk Thistle Seed Extract) has been used for centuries to support liver function. Gamma Oryzanol — a natural compound from rice bran oil — acts as a potent antioxidant specifically in the GI tract. Together they extend gut defense beyond the intestinal lining itself.

Lactoferrin for Microbial Balance Lactoferrin is a glycoprotein found naturally in colostrum that helps maintain healthy microbial balance in the GI tract — keeping the ecosystem inside your gut stable even under the stress of big training loads.

Your gut lining is one cell thick. L-Glutamine is what those cells run on — it rebuilds what training breaks down. The supporting cast here — Zinc and Vitamin A for immune and mucosal function, Gamma Oryzanol for GI antioxidant protection, Lactoferrin for microbial balance — covers the angles that L-Glutamine alone can't. This is a complete gut defense formula, not a single-ingredient fix.

How to Use SwissRX Gut Defense (Capsules)

Daily use: Take 2 capsules three times per day, or as directed by your healthcare professional.

Protocol tip: We recommend starting with SwissRX Gut Defense Powder for the first month — the powder delivers a higher dose of L-Glutamine for active repair. Transition to capsules as your daily maintenance dose once the lining is rebuilt. 

Consistency is everything: Gut health is cumulative. The athletes who see the biggest difference are the ones who don't skip days.

Dr. Kevin Sprouse, Head of Medicine for EF Education-EasyPost Pro Cycling, recommends SwissRX Gut Defense to all of his patients, calling it the single most effective gut supplement he's encountered. Athletes who stay consistent report that the GI issues that used to appear on long training days simply stop showing up.

SwissRX Gut Defense (Capsules) FAQ's

Everything you need to know before getting started.

The Feed Expert #1The Feed Expert #2The Feed Expert #3

The powder delivers a higher dose of L-Glutamine and is designed for active gut repair — especially during the first month or after a hard training block. The capsules are formulated as a daily maintenance dose, easier to sustain long-term. We recommend starting with the powder, then transitioning to capsules.

Take 2 capsules three times per day with meals, or as directed by your healthcare professional. Spacing doses throughout the day keeps your gut consistently supported rather than relying on one large dose.

Most athletes notice a difference within two to three weeks of consistent daily use. Gut health is cumulative — the athletes who see the biggest improvement are the ones who build it into their daily routine rather than taking it sporadically.

Yes — many athletes use the powder during heavy training blocks or race prep (when gut stress is highest) and the capsules as a daily baseline. Check with your healthcare provider if you have questions about combined dosing.
