Red Reishi belongs to a class of products known as adaptogens. For thousands of years, it has been prized for its ability to balance energy levels, reduce the negative effects of stress, and support the immune system. In traditional Chinese medicine, red reishi is said to benefit the heart, lungs, liver, kidney, and pancreas, and it is precisely for this reason that it helps to support and optimize the immune system. Red reishi is especially beneficial to the endurance athlete or “fitness buff”. Endurance athletes such as marathoners/runners, triathletes, and distance swimmers put their bodies through considerable stress in the course of training for their chosen event. Adaptogens like red reishi have the unique ability to help the body adapt to the effects of stress, and in terms of adaptogens, one of the very best is red reishi.
