Frequently Asked Questions
What is Nella by Fitbiomics?
Nella is a daily capsule of next-generation probiotics designed to help anyone pursue better holistic health. This includes benefits in digestion/bowel movements, energy, and sleep. We studied the microbiome (trillions of cells in the gut) of the most fit and healthy people thriving in the modern world, decoded what biologically makes them unique, and translated the extraordinary into these cutting-edge performance probiotic capsules. Nella is Informed Sport Certified, Vegan, Gluten Free and made in the USA.
What scientific credibility does nella by Fitbiomics to support their claims?
FitBiomics is a biotech startup spun out of the Wyss Institute for Biologically Inspired Engineering at the Harvard Medical School. Founded by a biomedical scientist and former athlete, Dr. Jonathan Scheiman built FitBiomics on the quest to benefit the health and wellness of everyone by decoding the microbiome of the most fit people in the world.
With a team of renowned scientists, we study the microbiome to identify novel probiotic bacteria that support optimal health. Utilizing next-gen metagenomic sequencing and purification, we isolate the probiotics that are abundant in super performers, analyze their genes and metabolic functions, and commercially develop them to support active lifestyles. In particular, we're sequencing elite microbiomes to identify and isolate novel probiotic bacteria for applications in performance and recovery.
FitBiomics is the microbiome discovery platform driving our scientific development of all our next-gen innovations (probiotics). Our research has been published in the Nature Medicine Medical Journal, protected with IP, and featured in hundreds of global media outlets.
What kind of benefits can I expect from taking Nella probiotics?
Nella provides benefits in supporting better digestion, better quality sleep, and better energy levels. An optimized microbiome has shown to support better immunity, brain function, stress levels, recovery and focus.,
When should I expect to feel the benefits?
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. For example, those with digestive issues may notice improvements within a week, but other benefits like improved immunity and energy can take months. As with any supplement, the impact may be gradual as balance is slowly restored to your gut bacterial community, addressing the core of your overall health.
What makes Nella different from other probiotics?
most of the probiotics on the market today are formulated from either plants, soil, baby poop, yogurt or other food sources. We believe, lets translate what makes super performers elite and revolutionize health for everybody.
