'Full Spectrum Myco-Products' are the complete fungal material consisting of all the biologically active components, such as the mycelium, the fruitbodies, the spores and by far the most important of all, the extra-cellular compounds that are produced throughout the entire life cycle of the organism. It is these extra-cellular compounds (compounds that are excreted outside of the cell and into the surrounding environment) and all the other 'survival' compounds that the fungus produces to give itself an advantage over the competing bacteria and microbes in the highly competitive environment in which it lives that are responsible for the main medicinal properties known from the fungal kingdom. These secondary metabolites have opened up the frontiers of medicine *and it is these properties that are removed through most extraction processes*. It is only in the 21st century that science has developed practical ways to reliably produce full spectrum myco-products which are now considered the current "Gold Standard" for most mushroom based dietary supplements. Be a smart shopper- most companies take the easy approach of growing or buying mushroom fruitbodies, and then making a tea which is spray dried and called a "hot water extract". Many claim this is the best form to use, or even that it is the only bioactive way to use mushrooms, which is of course nonsense, since mushrooms have been eaten for their health properties for thousands of years. The concept that extracts are better than anything else is yesterday's science and it does not reflect today's state-of-the-art knowledge. These "hot water extracts" are certainly better than trying to digest hard woody fruitbodies such as Reishi, but this extraction process entirely misses the potential health benefits which are offered by the extra-cellular compounds, which are not present in the fruitbodies. Relentless Improvement Hericium does NOT use a hot water extract!
