Corolius PSP (400mg) Mushroom Science Medicinal Extract

PSP is a recent addition to the family of medicinal mushroom products. Developed in China, extensive clinical testing did not begin until the early 1990's. Our product is an intra-cellular mycelial extract from the famous Cov 1 strain of Coriolus versicolor. The mycelium is produced through the deep layer cultivation method, which yields the most bio-actively potent mycelium for the raw material. ** Super Strength/PSK vs. PSP ** What is the Difference? There are three different therapeutic strength extracts derived from Coriolus versicolor. Super Strength and PSK are primarily protein linked and were developed in Japan. PSP is primarily peptide linked and was developed in China twelve years after the research on PSK was first published. To make PSP, the recipe for Super Strength/PSK is followed, then, as a final step, precipitation with alcohol is used to reduce the protein links to peptide links. The primary active compounds, the glucan structures, are unchanged by precipitation with alcohol. The glucan structure of the three different extracts is identical under NMR analysis. Coriolus Super Strength contains 600 mg per capsule vs. 400 mg per capsule for the PSP, and the Super Strength contains 42% actives vs. 30% for the PSP.
