Product Description
High-carb fueling shouldn’t come with a side of digestive distress.
SwissRX Happy Tummy is specifically formulated for athletes who fuel hard but need their gut to cooperate when it counts.
Whether you’re training your gut to handle race-day carb counts or need to de-bloat before smashing your next session, this isn’t just another probiotic – it’s your insurance policy against digestive distress.
Your Probiotic Arsenal Against Bloating
Attack bloating with targeted probiotic strains, such as Bacillus coagulans, which actively reduce bloating while optimizing protein digestion, and Lactobacillus plantarum, for enhanced gut-brain communication and muscle recovery.
This team is backed up by immune-boosting and digestion-aiding Bacillus subtilis, gut-resilience champion Bacillus clausii and Akkermansia muciniphila for metabolic health and gut lining support.
When you’re progressively training your gut to handle higher carb intakes, these 10 billion CFU work overtime to keep your digestive system adapting smoothly.
Gut Armor
SwissRX Happy Tummy goes on defense, too.
Gut-soothing ingredients like Slippery Elm (200 mg) and Marshmallow Root (200 mg) create a protective barrier in your digestive tract, preventing that heavy, uncomfortable feeling that can derail your session.
Add in Aloe Leaf (75 mg) for digestive health and 3 g of L-Glutamine to fortify your gut lining against exercise-induced stress, so you can push harder without digestive payback.
African Baobab (3 g) is rich in prebiotic fiber, and 250 mg of Vitamin C protects against oxidative stress.
Fueling Strategy Friendly
At just 25 calories and 3 g carbs, it won’t mess with your macro targets. The Tropical flavor (naturally sweetened with Rebaudioside M) means you won’t get flavor fatigue – it’s unique and refreshing compared to fueling products.
How to Use SwissRX Happy Tummy
Mix one stick with 8-12 oz of water or your favorite beverage. Take daily, preferably in the morning or post-workout, for optimal gut support and recovery.
If you’re training your gut to handle aggressive fueling strategies, SwissRX Happy Tummy supports the adaptation process. And if you suffer from bloating for other reasons, it will keep you comfortable and ready to perform.
Don't let the name fool you – this is bloating's worst enemy.

Happy Tummy FAQ's
Everything you need to know before getting started.



Take one stick pack every morning, ideally 30-60 minutes before training or your first meal of the day. Mix it with 8-12 oz of water or your favorite beverage. This timing allows the probiotics and botanicals to soothe and strengthen your gut lining before you start fueling, helping prevent bloating before it even starts.
Happy Tummy delivers 10 billion CFU of 5 targeted probiotic strains that fight bloating, combined with 6 gut-soothing functional ingredients. The probiotics help balance your gut bacteria and improve carb tolerance, while ingredients like botanicals work to reduce inflammation and support your gut barrier. Together, they help you fuel aggressively without digestive drama.
Unlike standard probiotics that just add bacteria to your gut, Happy Tummy is specifically formulated for endurance athletes who need to tolerate high-carb fueling. It combines targeted probiotic strains with functional botanicals in a convenient drink mix format that works fast. Plus, it only has 25 calories and 3g of carbs, so it won't mess with your macro targets.
Yes. Many GI issues during training stem from poor gut health and your body's inability to tolerate the high carb intake endurance sports demand. By improving your gut barrier function and carb tolerance, Happy Tummy helps reduce bloating, cramping, and other digestive issues that can derail your workout or race.
Most athletes notice reduced bloating within 1-2 weeks of consistent daily use. For gut training benefits (better carb tolerance), give it 2-4 weeks. Start before your big race so your gut is fully adapted when it counts.
