The Science-Backed Fix for Post-Training Bloat

By Matt Johnson

Founder of The Feed.

All that training and fueling can come with a price tag: bloating. It's not your fault; it's the result of pushing high-carb fueling and stressing our bodies. That is why we are so excited about this product.

Let's talk about the thing nobody mentions regarding high-carb fueling.

The bloating.

You finish a long workout, crushed your carb intake, felt great during the ride... then spend the next 3 hours on the couch feeling like a balloon.

The solution? It's called Happy Tummy from SwissRX.

This isn't your typical probiotic powder. It's a tropical-tasting drink that combines everything you need to stop bloating—whether it's from high-carb fueling or just everyday digestive issues.

Here's Why Most Debloat Products Fail

Most products just throw probiotics at the problem. But here's why that doesn't work:

When you're consuming massive amounts of simple carbs during training, your gut lining takes a beating. All that sugar creates an environment where bad bacteria can overgrow, your gut barrier gets compromised, and inflammation kicks in.

Probiotics alone can't fix that.

That's the breakthrough with Happy Tummy. It addresses both problems simultaneously.

Part 1: Repair the Damage First

The botanicals work to soothe and protect your gut lining:

Slippery Elm - Becomes a gel that coats your entire digestive tract. Creates a protective barrier and reduces inflammation.

Marshmallow Root - Forms a soothing layer over irritated tissue. Critical for athletes because intense exercise increases gut permeability.

L-Glutamine - Your gut cells use this as their primary fuel source. When you're training hard, glutamine stores get depleted, compromising gut barrier integrity.

African Baobab - Prebiotic fiber that feeds beneficial bacteria, plus antioxidants that combat exercise-induced oxidative stress.

These create the environment your gut needs to heal. Only then can the probiotics do their best work.

Part 2: Rebuild with the Right Probiotics

Five specific strains chosen for athletes:

Bacillus Coagulans - Survives stomach acid because it forms spores. Significantly reduces bloating and gas. Helps with that uncomfortable fullness after high-carb meals.

Akkermansia Muciniphila - The real game-changer. Lives in your gut's mucus layer and strengthens barrier integrity. People with higher levels have better metabolic health and reduced inflammation.

Lactobacillus Plantarum - Reduces markers of intestinal permeability after intense exercise. Helps break down carbohydrates more efficiently.

How to Use Happy Tummy

Use it 3-4 times per week preventatively.

That's the real discovery—you don't wait until you're uncomfortable. Take it regularly and the bloating just stops happening.

For acute bloating, it still works fast. Under an hour for most athletes. But the preventative approach is where the magic happens.

The tropical flavor is genuinely good. Not "tolerable because it works" good. Actually good.

Why This Matters

If you're serious about performance, you need to be taking in serious carbs. 80g, 100g, 120g+ per hour during hard efforts and races.

But if you're bloated and miserable for hours after every workout, you're not going to stick with it. You'll back off the fueling, your performance will suffer, and you'll never reach your potential.

Happy Tummy lets you fuel aggressively without the consequences. You get the performance benefits during the workout and actually feel good after.
