Mycologists claim that only ganoderma lucidum rather than ganoderna tsugae has adequate beta glucans, While this may (or may not) be true, there is more to mushrooms than the beta glucans, and your product meets all my requirements and tastes delicious in a cup of coffee or even a tiny glass of water. There is a sweetness that other mushroom products lack, probably due to the extraction process. My partner took some before airplane travel (since she often gets sick as a consequence), and did really well, too. She did not get sick!
