Every number on this page comes from peer-reviewed, placebo-controlled research. Here's the story, the scientists and the findings.
Where it started
Nomio's science has a 30-year backstory. It runs through the Swedish lab that changed how athletes think about nitrate, and gave the world the beet shot.
At Karolinska Institutet, Jon Lundberg's team saw nitric oxide jump to roughly 1,000 times normal in a student who had just burped. Tracing that spike revealed how the body turns nitrate from vegetables into nitric oxide.
Filip Larsen, first author alongside Eddie Weitzberg and Jon Lundberg, showed that dietary nitrate lowers the oxygen cost of exercise. That finding launched the beet shots endurance athletes use today.
The same researchers asked what else in vegetables changes how muscles handle hard work. The answer was isothiocyanates (ITCs) from broccoli sprouts. The catch: ITCs break down within hours.
A double-blind study in Redox Biology found lower lactate, less oxidative stress and better performance after a week of hard training with broccoli sprout ITCs.
After eight years of work, ITCs were finally stable enough to bottle. Nomio launched, and quickly spread through Olympic and world-class endurance athletes.
A second peer-reviewed study found lower lactate near threshold 3 hours after a single dose, the way Nomio is used today.
The team
Two researchers who have built their careers in exercise physiology, advised by the scientists who discovered the nitrate pathway.
The findings
In a double-blind crossover study, 9 active adults did 7 days of daily high-intensity intervals: once with broccoli sprout ITCs, the active compounds in Nomio, and once with a placebo. Here's what changed.
At the same submaximal effort after the training week. On placebo, lactate went up.
46 seconds longer in a max test, compared with 5 seconds on placebo.
Measured in muscle biopsies. On placebo, it went up.

Double-blind, placebo-controlled crossover. 9 active adults drank broccoli sprout juice twice daily during 7 days of high-intensity interval training, then repeated the week on placebo.
With ITCs: lactate at the same effort fell while it rose on placebo, time to exhaustion improved by 46 seconds (vs 5 on placebo), and oxidative stress markers in muscle and blood went down. NRF2, the body's antioxidant master switch, increased in muscle. VO2max did not change.
15 adults cycled at three submaximal intensities 3 hours after a single dose of a glucosinolate-rich sprout drink or placebo. Blood lactate was lower near the lactate threshold.
The effect followed a U-shaped dose curve: a moderate dose worked best, matching the ITC content of one Nomio shot.
Independently of Nomio, David Hood's lab at York University in Toronto treated muscle cells with sulforaphane, an ITC, while electrically stimulating them to mimic exercise training.
Sulforaphane increased mitochondrial respiration, mitochondrial content and the signals that build new mitochondria. The authors describe it as the first evidence that sulforaphane mimics the mitochondrial adaptations of training.
Built for hard training blocks
Hard weeks are where fitness is built, and where fatigue piles up. During that same week of daily intervals, athletes on ITCs showed clear signs of coping better with the load.
On placebo, max heart rate dropped 3 bpm after the week, a common sign of accumulated fatigue. On ITCs it held steady.
2 h 16 min a day on ITCs vs 5 h 21 min on placebo, tracked around the clock with glucose monitors.
The body's antioxidant master switch increased in muscle on ITCs, but not on placebo.
That's the stretch of training Nomio is designed for.
How we test
Supplement claims are easy to make. These are the standards behind ours.
Neither participants nor researchers knew who got ITCs and who got placebo.
Every participant was tested both ways, so each person is their own comparison.
Muscle biopsies tracked oxidative damage, NRF2 and mitochondrial function.
Continuous glucose monitors logged blood sugar 24 hours a day.
Several doses were tested. The best response came at a moderate dose, matching one Nomio shot.

Where the evidence ends
Honest science means saying where the evidence ends. Our human studies so far are small, with 9 and 15 participants, and were done in healthy, active adults in the lab.
The mechanism behind Nomio's effect is still being worked out.
Our next step is larger studies with trained athletes. We'll keep publishing what we find.

Anyone doing structured hard training: intervals, tempo runs, hill repeats, long races. Nomio's research was done with healthy, active adults, not elite pros.
Nomio is not recommended for children, or for pregnant or breastfeeding women.
Take one shot 3 hours before your hardest sessions or races. On your biggest days (VO2max work, hills, long structured runs), add a second shot 1 hour before bed. Most athletes use 1–4 shots a week. No more than 2 shots a day.

Nomio was developed over 8 years at Karolinska Institutet and the Swedish School of Sport and Health Sciences, by many of the same scientists who discovered nitrate's role in endurance performance. The key studies are summarized above.
Keep it refrigerated for the full 8-month shelf life. It also holds up at room temperature, so you can bring it to training, races and travel.
We're committed to clean sport. Nomio is on the Cologne List and has been tested for banned substances.
