Is the product made from mushrooms or mycelium?
Even though the label may say “mushroom”, you need to look at the Supplement Facts panel. For example, does it say Reishi mushroom? Reishi mushroom mycelium? Or Reishi mycelium? Some products will list the Latin name, Ganoderma Lucidum, without mentioning mushroom or mycelium.
Honest companies will reveal if the product is mycelium. They will also state in the “Other Ingredients” that there is grain or myceliated grain. Note that it is a requirement for herbal products to state “plant part” and also whether there are other unrelated materials present.
Many companies selling mycelium products will have the word “mushroom” everywhere. In their literature, label, website. Seeing the word mushroom so many times can obscure the actual product – low potency mycelium on grain.
