Increase Power Output and Endurance with PeakO2®

PeakO2® is an organic-certified combination of six adaptogenic mushrooms that are grown in the United States, including:

  • Cordyceps (Cordyceps militaris)
  • Reishi (Ganoderma lucidum)
  • King Trumpet (Pleurotus eryngii)
  • Shiitake (Lentinula edodes)
  • Lion’s Mane (Hericium erinaceus)
  • Turkey Tail (Trametes versicolor)

PeakO2® is a patented ingredient from Compound Solutions, one of the leaders in ingredient development and research within the sports nutrition industry.

PeakO2® is:

  • Informed-Sport & Informed-Choice Certified
  • Vegan
  • Gluten-Free
  • Non-GMO
  • Grown on organic oats in the USA

PeakO2® was specifically designed to help users adapt to and overcome both physical and mental stress, resulting in improved power output and endurance.

PeakO2® carries out its performance-enhancing effects by improving oxygen utilization and work capacity, while simultaneously reducing lactate levels. In other words, Peak O2® allows you to train harder and for longer.

PeakO2® appears to improve submaximal endurance performance as up to 2g/day has been shown to decrease blood lactate levels by 9% when subjects train at the same work rate. This essentially indicates that taking it helps your body exert less stress to meet the demands of exercise.

PeakO2®, in doses up to 2g/day, can improve endurance performance as seen by a 25.8 second time to exhaustion performance improvement in the Charleston study and a 70-second improvement in the UNC study. 

Supplementing with PeakO2® daily may improve:

  • Energy
  • Performance
  • Wellness
  • Endurance
