Mushrooms are the kings and queens of immune enhancement. Ergothionine is present in all mushrooms and has been called “the most significant longevity substance on earth”. But even more importantly mushrooms are loaded with beta 1-3 glucans which have incredible immune-boosting effects. I personally like a blend of 10 different cancer-fighting mushrooms because the synergy makes each work better. So 2+2+2+2+2+2+2+2+2+2 doesn’t equal 20 it equals 30!
