The Importance of Gut Health
Optimizing your gut health is something we talk about a lot. Layer the demands of training and racing on top of general life and environmental stress...you have a recipe for a disrupted gut. A healthy gut can contribute to your physical + mental well-being in innumerable ways. Here's the short version of what you can expect:
- Optimized digestion and nutrient absorption
- Improved sleep quality
- More energy
- Improved immune function
How to Use Nella:
Take one (1) capsule daily, or as recommended by a healthcare professional.
Probiotics take varying amounts of time to be effective for different people based on their DNA, gut health, and the bacteria currently making up their gut microbiome. Studies have shown that it can take up to 4 weeks for probiotics to start working and sometimes 6-8 weeks to feel a difference. Furthermore, different benefits of consuming probiotics are realized at different times.

Nella Performance Probiotic FAQ's
Everything you need to know about Nella Performance Probiotic.



Nella is a daily probiotic capsule from FitBiomics containing three patented Lactobacillus strains decoded from elite athlete gut microbiomes. It delivers 10 billion CFU per capsule, is NSF Certified for Sport and Informed Sport certified, and is formulated to support digestion, sleep quality, energy, and immune function. 30 servings per bottle.
Source and certification. Most probiotics use strains isolated decades ago from food or soil. Nella's three strains were decoded from elite athlete gut microbiomes — a fundamentally different starting point. Nella is also NSF Certified for Sport, meaning it's third-party tested for banned substances and safe for athletes competing under WADA, USADA, and USA Triathlon anti-doping rules. Most consumer probiotics carry neither certification.
Four to eight weeks for most users. Probiotics shift the composition of your gut microbiome over time, not acutely. Some users notice digestion changes within the first two weeks; sleep and energy effects typically take longer. Give it a full training block before assessing.
Yes — both NSF Certified for Sport and Informed Sport certified, third-party tested for banned substances and verified for athletes competing under WADA, USADA, and USA Triathlon anti-doping rules.
No. Nella is shelf-stable at room temperature — easy for travel and race-week packing. Avoid sustained heat above 75°F.
