This supplement has caused severe digestive distress for me. I have no other food allergies, and eat mushrooms all the time. Very disappointed.

This supplement is a great support for my father who was diagnosed with early stage Alzheimer over a year ago. I can honestly say that the formula has stopped the progression of this condition and he even seems to have more mental clarity since starting to use it. The doctor is also very pleased with the slow progression of the disease.
