I use reishi from Terrasoul, its definitely high enough quality to have the active ingredient in it. Make sure your supplement mentions a standardised percentage of polysaccharides and specifically names "beta glucans". Some companies will inflate their polysaccharide percentage with other kinds that arent beta glucans, so read into their claims.

Take my opinion with a grain of salt, however.
