The new and improved OPTYGENHP has been engineered to optimize performance for endurance athletes and is the best OPTYGEN formula we’ve ever developed.

This next-generation OPTYGENHP has been upgraded with the most potent blend of Cordyceps mushroom available to maximize your VO2max and time to exhaustion. In addition, there’s a clinically effective dose of premium grade Rhodiola because the latest clinical research shows the combination of these two endurance-specific adaptogens improves aerobic performance.

The main adaptogen in OptygenHP were first used by Tibetian Sherpas to help them climb Mt. Everest. OptygenHP contains this unique adaptogen because clinical research on elite endurance athletes shows it increases VO2Max, increase the body’s ability to adapt to high levels of physical stress, increase anaerobic threshold and reduce lactic acid.


A study done by South Dakota State University showed OptygenHP reduces cortisol levels (the primary stress hormone) by 26%. Chronically elevated cortisol levels can prevent an athlete from recovering, increase the risks of overtraining and suppress the immune system.


A 2012 study done at Luther College showed endurance athletes who used OptygenHP increased time to lactate threshold by 42%. The purpose of this study was to determine the effects on highly trained distance runners of OptygenHP.

Though changes in performance variables (VO2 max, hemoglobin, serum ferritin and salivary cortisol) were similar between groups, time to onset of lactate threshold was nearly 42% greater in E=experimental vs C=control group.
