What Makes PeakO2® Special?

PeakO2® isn’t your average mushroom mix. It’s a full-spectrum, unextracted blend of both mycelium and fruiting bodies from six powerhouse mushrooms: Cordyceps militaris, reishi, lion’s mane, shiitake, king trumpet, and turkey tail. This combo helps your body adapt to stress, boost power and endurance, balance your gut, and support immune health. Basically, it’s your all-in-one upgrade for body and mind.

Why PeakO2®?

Everyone’s talking about mushrooms, but at NOVA, we don’t jump on trends—we demand proof. That’s why PeakO2® made the cut: it’s a clinically tested, certified-organic, cultivated here in the U.S and packs a blend of six adaptogenic mushrooms, each with unique benefits. We’re here for real results, not hype.

The Science: Clinical Trials That Matter

We’re not here for “maybe” results. PeakO2® has been put to the test—twice.

UNC Chapel Hill Study (21 Days, Competitive Athletes)

Athletes taking PeakO2® were able to work out harder and longer—lasting over a minute more before getting tired and boosting their peak power—while those taking a placebo saw no such gains.

Peak Power: Athletes supplementing with PeakO2® saw a 17.6% boost in peak power output in just seven days, while the placebo group dropped by 11.8%.
Endurance: Time to exhaustion improved by 70 seconds for the PeakO2® group (only 5 seconds for placebo).
Anaerobic Performance: Enhanced oxygen use means you can push harder, longer.

College of Charleston Study (28 Days, Recreationally Active Adults)

Everyday active people using PeakO2® improved their endurance, had more energy for longer workouts, and recovered better, while the placebo group didn’t see these benefits.

Endurance: Significant improvements in time to fatigue after 28 days on PeakO2® (no change for placebo).
Blood Lactate: Lower blood lactate levels in the mushroom group, which means less fatigue and better recovery.
Heart Efficiency: Lower heart rate at the same workload—more work, less effort.
