Adaptogens are naturally occurring substances that normalize your body's processes during times of stress and exertion. They can help your immune response, aid absorption of nutrients, as well as increase stamina and strength. Optygen uses two of the main adaptogens used by Tibetan Sherpas to help them Climb Mount Everest.
