The complete system
Gut, brain, muscle, and immune benefits all in one stack.
FitBiomics decoded two separate microbiome pathways that elite athletes benefit from — one governing immunity and recovery, one governing endurance and power. The bundle addresses both.
- Rebuilds microbiome diversity and gut-immune barrier
- Regulates circadian rhythm for restorative sleep
- Produces butyrate for sustained cellular energy
- Reduces gut inflammation and bloating
- Supports short-chain fatty acid production
- Converts exercise lactate into propionate fuel
- Extends endurance and time-to-exhaustion
- Improves VO2 max by up to 13%
- Accelerates post-workout lactate clearance
- Reduces DOMS and next-day muscle soreness
How to use the bundle
One simple daily protocol.
One Nella capsule in the morning with a glass of water. The gut-immune-brain axis strains work with your circadian biology - use consistently to see the benefits on your sleep, inflammation, and mental capabilities.
One V·Nella capsule in the morning with a glass of water. With Veillonella in your system consistently, you'll reap the benefits of fighting fatigue from the lactate your muscles produce.
The bundle's effects compound. Within the first ten days you'll notice benefits in sleep, energy, endurance, recovery. Consistentcy will allow you to maximize the results as the benefits continues building through week 4 and beyond.
Human performance and longevity.
Both formulas decoded from elite athlete microbiomes.
Nella and V·Nella both originate from the same foundational research. This single study identified two distinct biological pathways: one governing the gut-immune axis (Nella), one governing the gut-muscle axis (V·Nella). The bundle is the most complete expression of that science.
The landmark discovery paper: full metagenomics sequencing of Boston Marathon finishers revealed Veillonella atypica enriched post-race in elite athletes. Transplantation into germ-free mice produced a 13% improvement in run time via propionate signaling — establishing the gut-muscle axis that powers V·Nella.

When both systems work together.
"4 months on the bundle. Nella fixed my sleep and digestion in two weeks. V·Nella kicked in at week 3 — I could push through the zone where I normally fade. I upgraded my whole operating system."
"Sleep improved first, then energy stopped crashing, then workout performance went up. It's exactly the order they described. I'm not going back to either one individually."
"The bundle converted me from skeptic to believer. Nella transformed my sleep and gut. Adding V·Nella changed my cycling — I used to dread climbs, now I almost enjoy them."
"I was hesitant to spend on both. Two months later I'm shocked at how different I feel. Better sleep, way more energy, better runs. It just works. The Harvard research is legit."
"As a triathlete I needed both — gut health for recovery and performance biology for race day. This is the only stack that addresses both scientifically. Game changer."
"My doctor was skeptical when I told her about it — then she read the research and told me to keep going. Sleep is the best it's been in a decade. Performance PRs every week."
What to expect
The bundle timeline.
Nella and V·Nella begin their processes. Early gut changes — regularity, reduced bloating. Most people notice Nella first.
Sleep improves noticeably (Nella). Performance gains begin — workouts feel more sustainable, recovery is faster (V·Nella).
Energy is consistent. Soreness is reduced. Athletes hit new performance benchmarks. Sleep is deep and reliable.
Both axes fully established. This is your body operating at the biological level it was meant to. The compound gains continue.
