JHS Naturals Reishi is available in a 150 capsule size. The Red Reishi fruit body (Ganoderma lucidum) has the most complex constituent profile of any of the well known medicinal mushrooms (or their mycelium). Like many medicinal mushrooms it contains polysaccharides, ergesterols, and adenosine compounds. However, unique to this species are the "ganoderic acids" or "triterpenes". Contained within the hard, shiny red surface of the mushroom, these are the compounds beneficial for liver and cardiovascular health.
