What V·Nella does
Performance from the inside out.
V·Nella targets the gut-muscle axis — the biological pathway connecting your microbiome to lactate metabolism and muscular endurance.
Lactic Acid Conversion
V·Nella's Veillonella atypica strains consume lactate produced during both high-intensity and daily activities and convert it into propionate — the SCFA which re-enters circulation as fuel, extending your performance window before fatigue.
Endurance
V·Nella improves your ability to run until exhaustion and motivates voluntary exercise — not through stimulants or willpower, but through microbiome optimization. When your gut converts lactate to fuel, your body simply keeps going longer.
Amplified Recovery
By upcycling lactic acid during recovery and turning it into propionate, V·Nella creates alternative fuel and triggers anti-inflammatory responses — reducing soreness, accelerating next-day readiness, and improving training consistency.
The mechanism
How V·Nella upcycles your fatigue into fuel
V·Nella's strains were selected from elite endurance athletes — not elite marathoners specifically, but individuals chosen through elite endurance performance for optimized lactate metabolism. These are the microbes thriving in the world's most efficient biological systems.
During physical activity, lactate floods the bloodstream and enters your gut. Veillonella atypica consumes this lactate as a carbon source, fermenting it into propionate — a short-chain fatty acid that circulates back as usable aerobic fuel.
Propionate enters cells and drives ATP signaling — making metabolic fueling more efficient. The result: more usable energy during peak effort, reduced perceived exertion, faster lactate clearance, and measurable improvements in time-to-exhaustion.

The research that made V·Nella possible.
From discovery to pre-clinical to clinical studies. Here's the science that V-Nella brings in a daily capsule. Pre-clinical published in Nature Medicine, 2019.
Real athletes, real results
Built for people who push limits.
After 3 weeks of use, I did a 600-mile bike ride over 6 days — with NO lactic acid build up and legs feeling fresh every day. I knew this was going to disrupt the endurance field. An amazing innovation.
As a 59-year-old runner whose fatigue level has increased in recent years, I figured I'd give it a try. After 3 days I noticed a decrease in fatigue. After 10 days, my legs felt fresh while walking up 7 flights after a run.
V-Nella is giving me insane energy. I am a 57 year old post-menopausal woman who has been chronically tired for decades. I started four months ago and I am working out five days a week and I am literally never tired. Life changing.
As an MTB athlete in the CAT 1/Open-Pro category, I have more than a decade of data on Training Peaks. After only two weeks of V-Nella, my power output and recovery metrics changed meaningfully. The data doesn't lie.
I've been taking V·Nella for 3 months and my endurance is noticeably longer. By mile 15 I used to fade — now I still feel strong. Recovery is genuinely faster, I used to need 48 hours between hard efforts, now 24 is enough.
As a cyclist I can tell a tangible difference. I climb longer, push harder without the leg burn, and recover faster. The science is legit. This is in my permanent training stack.
6 weeks in and my zone 2 heart rate is lower at the same pace, post-workout soreness is noticeably less. I PR'd my half marathon by 4 minutes after 8 weeks — V·Nella was the only change I made.
I've been taking Nella for over a year and V·Nella since it came out. I'm an endurance runner — marathons, ultras, longest 100k. My legs rarely get really tired anymore and I credit this. Thank you to your scientists.
What to expect
Performance compounds over time.
Veillonella establishes in the gut. Subtle gut microbiome shifts occur. Not much to feel yet - the biology is priming.
Lactate conversion begins. Users typically notice longer sustainable effort, slightly less burning at threshold. Recovery starts improving.
Measurable improvements in time-to-exhaustion. Next-day soreness decreases. Training consistency improves as recovery becomes faster.
VO2 max gains consolidate. The new performance ceiling is your baseline. Athletes report this as their best sustained athletic form.
Why V·Nella is different
No stimulants. No crash. Just biology.
Every other performance product hits your nervous system harder. V·Nella works by making your cells more efficient with the energy they already produce.
Comparisons reflect typical, publicly available product and ingredient information. Individual brands vary.
Complete the system
Pair V·Nella with Nella for total-body gut performance.
V·Nella handles the gut-muscle axis — endurance, lactic acid conversion, and performance. Nella handles the gut-immune axis — sleep, digestion, and daily energy. Together they address every dimension of performance biology. Save $45 with the Health Bundle.
