OPTYGEN HP, now with Ashwagandha Root has been engineered to optimize performance for endurance athletes and is the best OPTYGEN formula we’ve ever developed. Ashwagandha Root is used as an "adaptogen" to help the body cope with daily stress, and as a general tonic.

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.
