DOES IT WORK?
Results vary. Split Gill Polypore is actually one of the more interesting lesser-known mushrooms. Schizophyllan (its unique beta-glucan) has been studied as an injectable immunotherapy adjunct in Japan. But that's injectable, not oral. As an oral supplement, the evidence drops off significantly.
