To give you further details about the bitterness of Reishi, the bitterness comes from the beneficial triterpene compounds. These compounds give reishi its bitter flavor. These compounds are found in the mushroom and our product is extracted exclusively from the mushroom (fruiting body).
You want a reishi product to be bitter. If a reishi product is not bitter, start asking questions.
Many so-called reishi products do not taste bitter and this is a perfect indicator of the product not containing any detectable amounts of the beneficial triterpene compounds. This is either due to inferior extraction or the product not being made from the mushroom.
