Express Delivery SwissRX Fiber

You may not be struggling with a fueling problem, you could be fighting a gut problem. If you’ve ever dealt with mid-race GI distress, unpredictable digestion during big training blocks, or wild hunger swings that derail your recovery, your gut is the limiter long before your legs are.

SwissRX Fiber is the first fiber supplement actually designed for endurance athletes’ gutsnot bathroom emergencies.

Built for Performance, Not BloatDelivers 11g of strategically selected fibers that won’t congest, clump, or turn into gel in your bottle. Unlike traditional fiber supplements that expand in your stomach and wreck your training, this next-generation formula stays smooth from first sip to finish. You can sip it throughout the day or enjoy it over iceno “mix and chug” panic required.

Feeds the Bacteria That MatterThis isn’t generic psyllium husk. SwissRX Fiber specifically supports keystone gut species like Akkermansia, Bifidobacterium, and F. prausnitziithe bacteria linked to improved gut barrier integrity, better carbohydrate tolerance, and reduced inflammation under training stress. Translation: a gut that holds up when volume is high.

Stabilizes Energy Without the CrashesThrough short-chain fatty acid production, SwissRX Fiber helps stimulate GLP-1 and PYYhormones that control blood sugar response and satiety signals. That means fewer wild hunger swings during big mileage weeks and more consistent energy when you’re stacking hard days back to back.

The formula combines eight clinically researched fiber sourcesresistant starches, fruit fibers, beta-glucans, and prebiotic fibersto increase microbial diversity and support regularity without urgency. This is gut support that compounds over time, not just a short-term fix.

How to Use SwissRX Fiber

Daily: Mix 1 scoop (16.7g) with 6-8 oz of water once daily, ideally in the morning or between meals. Use liquids below 140°F to preserve the prebiotic activity.

Timing Strategy: Take it away from your hardest training sessions to avoid any fullness during workouts, but make it a non-negotiable part of your daily routine.

Pro Tip: Start with half a scoop for the first week if you’re not used to higher fiber intake, then gradually increase to the full serving as your gut adapts.
