PeakO2 is Informed-Sport & Informed-Choice certified, vegan, gluten-free, non-GMO, and 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, and endurance.
