History of the company
Started in 1994, Mushroom Science was originally named "JHS Natural Products" after the three founders, John Seleen, a mushroom grower, He Xianguo, a natural products chemist and Steven Bailey, a naturopathic doctor.
The company was started in an effort to introduce PSK (polysaccharide-K) to American health care practitioners. PSK is extracted from the medicinal mushroom, Coriolus Versicolor. PSK was the top-selling immune support supplement in the world and the most potent Coriolus Versicolor extract available. Although there was Coriolus Versicolor extracts being sold in the U.S. at the time, none of them were as potent or as well researched as PSK.
Who we are and why we are different
A cutting-edge company
A true pioneer in the mushroom supplement industry, Mushroom Science was the first company in North America to offer Coriolus Versicolor mushroom extracts matching the quality and content of the PSK used in world-renowned Japanese research.
Hot water extraction
Mushroom Science is the only U.S. Mushroom Company that offers hot water-extracted mushroom supplements that match the potency and quality of the preparations used in Traditional Chinese Medicine. Hot water extracts are the only kind of mushroom supplements ever used or studied in scientific research and the only method of preparation used in traditional herbal practice. Each of our products is prepared using a hot water extraction process and is sold in an encapsulated powder form.
The science of hot water vs. other forms of extraction
Hot water extraction is the only scientifically validated process for releasing the immune-supporting polysaccharides (beta-glucans) into a bioavailable form.
Alternative methods of extraction, including mushroom supplements preserved in alcohol (a.k.a. "cold water extracts"), or unextracted mycelium powder (made by growing mushroom mycelium on sterilized rice), have not been scientifically tested and offer no evidence of comparable immune benefit. There is no research to support the science behind these alternative extraction methods, making it impossible to know what immune health benefits they may provide.
Committed to Science
Mushroom Science maintains a strong commitment to the science supporting the immune health benefits of medicinal mushrooms. Clinical research has been conducted on the following of our products: Coriolus Super Strength, Reishi Gano 161 and MaitakeGold.
Committed to Consumer Education
Committed to helping health practitioners and customers select only the most effective supplements for immune health, Mushroom Science always lists potency information in the supplement facts panel of every label. Mushroom Science encourages consumers to check labels, to verify that a manufacturer provides potency information by listing the actual percentages of active compounds in their mushroom supplements.
Committed to Proper Preparation
Mushroom Science is built upon a belief that no other supplement provides greater benefit for immune health than properly prepared medicinal mushroom supplements. Initially used in Chinese herbal preparations, medicinal mushrooms were traditionally prepared as a tea by steeping in hot water. Modern science confirms this traditional knowledge and recognizes the hot water extraction method as essential to preparing effective mushroom supplements.
