Frequently Asked Questions

Nella is the world’s first athlete-derived Performance Probiotic. It is a daily capsule of next-generation probiotics designed to help anyone pursuing a healthy and active lifestyle to a new frontier of personal best from the inside out. This includes benefits in digestion/bowel movements, energy, and sleep. Nella is the fruition of years of cutting-edge research, decoding the microbiome of some of the most fit people in the world. Nella is made with our patented next-generation Lactobacillus probiotic strains sourced from the guts of elite athletes, giving you the Guts to Defy your Limits, Nella is Informed Sport Certified, Vegan, Gluten Free and made in the USA. #GutsToDefy

Nella is for EVERYONE who can benefit from gut health. We know that gut health supports holistic health and wellness. So Nella is for anyone who wants to live a more active life. From elite athletes to wellness seekers, we aim to help you take charge of your destiny, to excel and succeed in all aspects of life. When we feel our best, we can be our personal best.

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 the microbiome of elite athletes 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). After years of cutting edge research, we have isolated hundreds of proprietary strains, including the discovery of a game-changing lactic-eating bacteria, Veillonella, for application in sports performance and recovery. Our research has been published in the Nature Medicine, protected with IP, and featured in hundreds of global media outlets. We recently launched our first product, Nella, for gut health applications and are actively working on future game changing probiotics, including bringing Veillonella to the market!

Yup, our probiotics are coming from the gut bacteria of someone else… specifically super performers. But all probiotics have an origin story. Most probiotics on the market today are actually collected from baby poop, cheese, and plants. We work with Olympic, Professional, and nationally ranked athletes across a variety of sports with different backgrounds to unlock what is commonly enriched in their microbiomes. Our athlete-derived genetically unique strains have distinct metabolic properties that support the intense physiological demands of athletes that benefit anyone and everyone pursuing a healthy and active life. That’s why we say From Athletes. For You.™

Nella is different from other probiotics because we went straight to the source: the guts of super performers. By understanding and decoding how elite athletes' microbiome supports their sport's intense physical demands, we are cultivating probiotics to better support your active lifestyle and defy your limits. While most probiotics on the market today come from either food, baby poop, soil, or random individuals, all of our next-gen probiotics have been identified, sourced, and decoded from super performers. 

Our mission is to empower, educate, and elevate human potential, driving transformation from the inside out. We aim to inspire and build a world where greatness is possible for everyone, forging the new frontier of human health and performance. We are committed to using microbiome science and technology as a force for good to unleash the best in every body!

We believe form fits function. That's why we cultivate probiotics that work within the microbiome of elite performers. We're revolutionizing the way people understand and optimize their bodies by decoding the biology of super performers. Rather than looking at how to fix disease, we work with fit people as a proxy for understanding what drives optimal health. This allows us to cultivate next-gen probiotics that are more fit to support the diversity and demands of today's wellness needs.

We are bridging the gap between sport and science, bringing communities together, and inspiring the next generation of scientists, athletes, entrepreneurs, and more.

In short, yes you can combine Nella with other probiotics. Probiotic brands vary by the strains/amounts of each strain they contain. While many probiotics are sourced from a handful of manufacturers (you can find the same strains used in many different brands), the strains we use in Nella are our own proprietary strains. That means you will not find our strains in any other probiotics brand. Nella contains a blend of our patented Lactobacillus plantarum, Lactobacillus rhamnosus, and Lactobacillus acidophilus strains. We would suggest transitioning to using only one to see how it effects you personally (as everyone is different), before experimenting with combinations.

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.

There are a few reasons why you might not notice any benefits to taking Nella probiotics. First, the probiotics have expired. Check your Nella packaging to make sure the expiration date has not passed yet. Second, you are already consuming a lot of probiotic foods. If you are already eating and drinking a lot of probiotic foods like yogurt, kimchi, sauerkraut, kefir, kombucha, etc., you might not notice as many changes when taking Nella probiotics. Third, you have not taken the probiotic long enough. Some benefits can take weeks or months to manifest as your body adjusts to the probiotic. Finally, everyone is different. Everyone has a different genetic code, a different microbial community in their gut, and different dietary and exercise habits. FitBiomics is planning to develop many new probiotics in the future, so if this one is not working out for you, keep checking back for when our next probiotic will be released. 

Nella probiotics are safe for most people to take. However if you are pregnant, lactating, have a serious health condition, are taking any medications, or are planning medical or surgical procedures, consult your physician before use of any new probiotic or supplement! Probiotic use for children should be discussed with your pediatrician.

All of our probiotics have been genomically sequenced and decoded to identify the presence of both functionally beneficial genes (amino acid, vitamin biosynthesis, etc.) and an absence of detrimental genes (antibiotic resistance, toxins) to validate properties. They are manufactured in GMP-compliant facilities followed by rigorous purity and QC testing to ensure our product adheres to the highest commercial food grade and supplement standards. We have also performed functional beta testing for our next-gen Nella supplement with several hundred people. While not an official clinical study, our users reported benefits in digestion, energy, recovery, and quality of sleep .**

We are also planning official clinical trials to validate performance and complement the anecdotal feedback collected through measurements of biomarkers. As a microbiome startup, we're building a new frontier of fitness and nutrition and always looking for more feedback to optimize our technology and products. Please reach out and let us know about your experience or share a review of your experience!

No, Nella does not need to be refrigerated. Nella probiotics are packaged in Alu Alu blister cards which protects the capsules from exposure to light, oxygen, and moisture.

Our gut is the epicenter of health and wellness. Approximately half of our cells are microbial, with 70% of our immune cells located in our gut.

Probiotic consumption can influence overall health through the many benefits of improved gut function, including aiding digestion for nutrient absorption and metabolism, outcompeting "bad bacteria", as well as promoting the growth of "good bacteria” that can strengthen the mucus lining of the gut. Beyond the gut, probiotics can balance the pro- and anti-inflammatory actions of our immune system and even produce neurotransmitters to benefit brain function. Collectively, these functions can support energy levels, muscle development, endurance, as well as sleep and mental toughness.*

It typically can take your body 3-4 days to adjust when starting new probiotics, especially if you were not taking any prior, but it's not uncommon for these side effects to last about a week. This can include mild gas, bloating, or more frequent trips to the bathroom, all of which subside within a week. While rare, if you do experience anything worse than these symptoms, discontinue use and notify us at customercare@fitbiomics.com!

Probiotics side effects usually mean that the good bacteria are working. The most common side effects include mild forms of diarrhea, gas, bloating, cramps, rashes, or acne. Most people will only experience side effects for 3-4 days, certainly less than a week. If you continue to experience side effects for more than a week, please contact us at customercare@fitbiomics.com.

One way to minimize side effects and increase the likelihood of benefits is to take Nella within 30min before eating a healthy meal full of healthy fibers and sugars (like oatmeal and fresh fruit with a glass of milk).

We suggest making your probiotics a part of your routine! Take daily at a time that is most convenient for you to stay consistent each day. Probiotics tend to work best when taken with or 30 minutes before a meal containing healthy fibers and sugars, like oatmeal with fresh fruit. However, everyone's microbiome is unique and each person's experience will vary, so it is important to pay attention to what your body is telling you feels best.
