The Lactic Acid Metabolizer

MAKING FATIGUE OBSOLETE. We’re introducing an entirely new energy mechanism into the body that was previously only found in elite athletes. It’s microbiome-led, mitochondria-supported and offers a new path forward – clean energy from within. Some energy drinks may give you wings, but V•Nella is like rocket fuel for your muscles.

Reduced Fatigue

Converts lactic acid, an exercise by-product associated with fatigue, into propionate, a beneficial short-chain fatty acid (SCFA) to fuel your muscles. 

Increased Endurance

Improves physical activity and VO2 max by using propionate as an alternative fuel source for your cells.

Faster Recovery

Reduced fatigue, inflammation, and more efficiently powered muscles support recovery and repair. 

Better Mitochondrial Function

Provides clean energy at the cellular level supporting ATP production, metabolic health, and longevity.

3-in-1 Performance Probiotic 

SLEEP BETTER. POOP BETTER. RECHARGE BETTER. We like to say sleep is the most powerful performance enhancer. Nella improves gut health and sleep quality by reducing stress, inflammation, and cortisol levels — so you wake up rested and ready to perform.

Better sleep quality

Nella reduces reactive oxygen species and inflammatory cytokines to support significant improvements in sleep quality, easing falling asleep and reducing disruptions through the night.

Optimized Digestion

Provides enhanced gut microbiome health by promoting growth of beneficial microbes, reducing gut dysbiosis for better bowel movements.

More Energy

Improves free testosterone to cortisol ratio associated with recovery (energy > stress). Provides natural energy by increasing biosynthesis of vitamin K.

What Experts & Customers Are Saying

Read the overwhelming feedback from real world people who have experienced the life changing benefits of Nella and V•Nella.

The gut is one of the most important body parts. People might think that it's your legs or your core muscles, but the gut has a bigger impact on race day than any other body part. 

As an ultra runner, my gut is almost always what limits my performance in long races. FitBiomics is addressing this in a way no one else has.

- Kyle Peitari, ultra marathon runner
 

Fatigue down, VO2 Max up

“I am a 59-year old runner whose fatigue level has increased in recent years. After 3 days on V•Nella, I noticed a decrease in fatigue. After 10 days, my legs felt fresh walking up 7 flights after a run. 2 months in, I had shaved a whopping 30 seconds per mile off of my run time, without even trying (no interval training). After 3 months. I now feel energetic during my runs, and (amazingly!) my VO2 max is on the rise. I feel V•Nella has set back the clock by 10 years, and the results just keep on improving.”

More stamina, all day energy!

"The transformation in my energy levels and stamina was gradual yet profound. My stamina increased significantly, enabling me to sustain longer workout sessions—from under 60 to over 90 minutes. This boost wasn't the short-lived jolt you get from caffeine but consistent, all-day energy that improved my overall activity level, from intense workouts to playful interactions with my children. One of the most notable benefits was the dramatic reduction in recovery time between workouts and the absence of the usual post-workout soreness. This has allowed me to pursue more frequent and intense training sessions without the apprehension of next-day pain, fundamentally changing my approach to fitness.

Legs feel amazing

"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. Thank you to your scientists for figuring out this level up unlock!"

PR'd on day 8 of VNella

“I am a 38-year old mom of two kids 5 and under, and my workouts have not been what they used to be before kids despite trying to get back into it. I've been looking to maximize my 30-min workouts - it is what I have time for these days. After 3 days, I started to sleep better and noticed my energy levels increase during the day and my ability to push myself during strength and cycle workouts improve. Today I set a new PR on the peloton bike without even trying that hard - I hadn't set a new PR in this format despite really trying to for many, many months. Looking forward to seeing continued improvement in the next few months.”

Life Changing

“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 taking V•Nella about four months ago and I am working out five days a week,

losing weight, and I am literally never tired.”

V•Nella / Verified Customer

Power & VO2 Max improved in just 2 weeks!

“As a MTB athlete racing in the CAT 1/ Open-Pro category, I have more than a decade of data on Training Peaks to compare, and after only two weeks of taking V-Nella, I can tell you that the data doesn't lie! After two weeks, my power is up, my perceived effort is down, and my VO2 max (per the Garmin app) is up from 74 to 76! Even better than that, my quality of sleep has improved significantly. I wake up refreshed and ready to hit another day of training. To top it off, I am down two pounds in body weight"
