Have you ever actually read the nutrition facts on the back of your mushroom supplement?
If not, I totally recommend you take a look!
Of course, if your supplement is made from actual mushrooms, then you won’t find anything too surprising.
The species of mushroom will be listed, along with the amount in each serving. You might also see the “beta-D-glucan” content, or the level of active compounds verified to be in the extract.
On some supplements however, they’ll list terms like “myceliated grain”, “mycelial biomass’, “cultured oats”, or even “freeze-dried myceliated brown rice”.
