Decoded at Harvard Medical School
Elite athletes have unique microbes in their gut that drive peak performance.
Now you can too.
Researchers at the Wyss Institute for biologically inspired engineering sequenced the gut microbiomes of ultra-marathoners and olympic athletes and published their finding in Nature Medicine. They discovered that elite runners carried high abundances of Veillonella atypica - a bacteria strain almost entirely absent in sedentary individuals. This microbe converts lactic acid, the byproduct of exercise, into propionate: a short-chain fatty acid that fuels muscles and activates the gut-mitochondrial signaling pathway. This lead to the creation of V-Nella and Nella after years of metagenomic translation and clinical validation.

FAQ
Everything you need to know.
What's the difference between Nella and V·Nella?
Nella targets the gut-immune-brain axis — it's your foundation for daily gut health, improved sleep quality, and sustained baseline energy. V·Nella targets the gut-muscle axis — it's designed for performance, converting lactic acid into propionate fuel and supporting the metabolic pathways that drive endurance and reduce fatigue. Many customers take both as the Health Bundle: Nella handles rest and recovery, V·Nella handles output and performance.
How is FitBiomics different from normal probiotics?
Traditional probiotic strains have been around for decades and created from soil and other old bacteria. FitBiomics strains were discovered in 2019 via full metagenomics sequencing of elite athletes at Harvard's Wyss Institute. Our formulas have undergone IRB-approved, placebo-controlled, randomized clinical trials on the final product — not just individual ingredients. Every batch is third-party tested for purity, potency, and label accuracy.
Can I take FitBiomics if I'm on a GLP-1 medication?
Yes — and many customers specifically take FitBiomics alongside GLP-1 medications like semaglutide. GLP-1 drugs can cause digestive discomfort, fatigue, and disrupted sleep, as well as a loss in lean muscle. V·Nella's Veillonella atypica produces propionate that directly stimulates the body's own GLP-1 secretion via the gut-brain axis, while Nella helps protect gut integrity by restoring microbiome balance. As always, consult your physician before adding any supplement while on prescription medication.
When should I take my capsule?
Each product is one capsule per day. Both Nella and V-Nella can be taken in the morning before breakfast with water. Consistency is key: most customers notice meaningful results within 10–14 days, with full benefit at the 4–8 week mark.
Is FitBiomics HSA / FSA eligible?
FitBiomics products may be eligible for reimbursement through certain HSA and FSA plans, depending on your plan administrator's guidelines. We recommend checking with your plan administrator directly. Many customers submit their FitBiomics receipts for reimbursement and are approved. Contact us at team@fitbiomics.com if you need a letter of medical necessity or additional documentation.
