FitBiomics Performance Lab · Open Enrollment

Your wearable data could advance the science of human performance.

We're recruiting Nella and V·Nella users with wearable devices to contribute data to our ongoing performance research. Your body's response helps us understand — and prove — how microbiome science translates to real athletic results.

✓ Takes Nella or V·Nella ✓ Wears Apple Watch, Oura, Garmin, or WHOOP ✓ Trains at least 3× per week ✓ Willing to share anonymized wearable data

Spots are limited — we onboard in cohorts of 50.

Your wearable.
Your data. Your proof.

We're building a live dashboard where you can track your own response to Nella and V·Nella over time — HRV, readiness, resting heart rate, and more.

Keep reading below to see Jonathan's real results tracked through Oura — a preview of what personalized performance data looks like for a founder who's been on the protocol since day one.

The Process

How the Performance Lab Works

Step 01

Apply

Fill out the form above. We review applications and onboard in cohorts of 50 participants at a time.

Step 02

Connect Your Wearable

After onboarding, you'll connect your device data through our secure partner integration. Your data is anonymized before it reaches us.

Step 03

Take Your Protocol

Continue taking Nella and/or V·Nella as normal. We track baseline vs. results over a 60-day window.

Step 04

Get Your Report

At the end of the study period, you receive a personalized performance report showing your individual results vs. cohort benchmarks.

From the CEO

Jonathan's data. Published results, personal proof.

Jonathan Scheiman doesn't just run the company that makes these products - he's a subject in the data. As a high-level athlete and the researcher who identified Veillonella atypica, Jonathan has been taking the full bundle since day one and tracking every metric.

His results mirror what the clinical trials show - but seeing them in one person's continuous wearable data over 6 months tells a different story than a 4-week trial. Over 163 days of continuous Oura Ring tracking, heart-rate variability (HRV) reversed course and resting heart rate moved in the opposite direction at the same time — the pairing you'd expect if the change were physiologically real. All this to say, even with the stress of running a company, Jonathan was able to keep his cool by taking V·Nella.

What People Say

★★★★★

"After only two weeks of taking V-Nella, I have more than a decade of Training Peaks data to compare — the data doesn't lie. My power is up, my perceived effort is down, and my VO2 max jumped from 74 to 76."

Verified Customer
V·Nella · MTB Athlete
★★★★★

"I've been taking Nella for well over a year and V·Nella since it came out. I'm an endurance runner — marathons, ultras, longest is 100k. My legs rarely get really tired and I credit this stuff."

Verified Customer
Health Bundle · Ultra Runner
★★★★★

"2 months in, I had shaved 30 seconds per mile off my run time really without even trying. My VO2 max is on the rise. V-Nella has set back the clock by 10 years, and the results just keep improving."

Verified Customer
V·Nella · Runner, age 59
★★★★★

"I've been struggling with bad sleep and gut health due to SIBO. Taking Nella has completely solved for my motility and sleep quality. I fall asleep and stay asleep — honestly in disbelief. I highly recommend this product."

Verified Customer
Nella · Gut Health
★★★★★

"After 3 days I started sleeping better and my ability to push myself during workouts improved. I set a new PR on the Peloton without even trying that hard — I hadn't set a new PR despite really trying for many, many months."

Verified Customer
V·Nella · Strength & Cycling
★★★★★

"Been taking these products together for a few months and when I ran out, WOW I noticed the difference. These keep me at my best. Energy, sleep, and a regulated gut."

Verified Customer
Health Bundle
★★★★★

"I tend to do 90–120 minute resistance training sessions and I felt just as energetic at the end. My muscles felt resilient and I was solely limited by aerobic capacity — not fatigue."

Verified Customer
V·Nella · Resistance Training
★★★★★

"I have felt more regular as Nella continues to help optimize my gut. I also notice better sleep quality when I take it versus when I miss a day. Highly recommend!"
