Harvard-developed probiotic science for real results
GLP-1 medications are powerful tools for weight loss — but they come with side effects that disrupt the very systems that keep you feeling alive, energized, and strong. It’s not a character flaw. It’s biology.
“GLP-1s help you lose weight, but they weren’t designed to protect your gut health, your energy, or your metabolism. That’s where Nella comes in.”
— FitBiomics Research TeamEnergy Drain & Fatigue
GLP-1s slow digestion and suppress appetite, leaving you feeling drained and unmotivated — a cycle that makes everything harder.
Muscle Loss, Not Just Fat
Without enough activity and support, the weight you lose can include lean muscle — weakening your body and slowing recovery.
Gut Disruption & Imbalance
GLP-1s alter how your gut moves food and disturb the healthy bacteria your body relies on for digestion, mood, and balance.
Your gut health partner on the GLP-1 journey.
Nella is a next-generation probiotic developed from the microbiomes of elite athletes — engineered to restore gut balance, revive energy, and protect your metabolism while you lose weight.
Restore Energy
Fight the fatigue that comes with reduced digestion and caloric restriction. Feel like yourself again, day after day.
Heal Your Gut
Replenish the beneficial bacteria disrupted by GLP-1s. Reduce bloating, improve regularity, and restore digestive harmony.
Protect Metabolism
GLP-1s change how your body uses fuel. Nella helps maintain metabolic balance so your body keeps burning efficiently.
Sleep & Recovery
Your gut microbiome directly regulates sleep quality through the gut-brain axis. Nella supports deeper sleep cycles, overnight muscle repair, and the full-body recovery your GLP-1 journey demands.
How Nella works inside your body.
GLP-1 Disrupts
GLP-1 medications slow digestion and suppress appetite, altering your gut environment and allowing imbalances to accumulate.
Nella Enters
Nella delivers a breakthrough probiotic strain discovered in elite athletes — Veillonella atypica — that feeds on lactic acid in your gut.
From elite athlete microbiomesFatigue Becomes Fuel
As it consumes lactic acid, the probiotic produces propionate — a clean, natural energy source your body uses for movement and recovery.
Clean, gut-powered energyYou Thrive
More energy, better gut balance, improved digestion, and deeper sleep for overnight recovery.
Stronger, lighter, balancedThe research behind Nella was published in Microbiome Journal, a leading peer-reviewed journal, validating the next-generation probiotic strains found in elite athlete gut microbiomes.
Science decoded from the world’s fittest microbiomes.
FitBiomics founder Dr. Jonathan Scheiman led research at Harvard’s Wyss Institute studying the gut microbiomes of elite marathon runners and Olympic athletes — unlocking probiotic strains unavailable anywhere else.
The probiotic designed for your GLP-1 journey.
GLP-1 medications change how your gut works — affecting your digestion, energy, sleep, and the bacteria that keep you balanced. Nella was developed from the microbiomes of elite athletes to restore what GLP-1s disrupt, so you can lose weight without losing your vitality.
People just like you are feeling the difference.
I've been on Ozempic for 6 months and the fatigue was real. After two weeks on Nella, I have noticeably more energy and my digestion finally feels regulated again. I wish I'd found this sooner.
I sleep better, recover faster, and feel more energetic during the day. The bloating I was experiencing on Wegovy has almost completely gone. Highly recommend to anyone on these medications.
Taking Nella feels like I upgraded my body's battery. I have more energy, I keep up with my kids, and I walk into my workouts ready to go. It allows me to stay active while losing weight.
