YZ Polysac is a mushroom essence derived from the fruiting bodies of 100% pure wild Yun Zhi (Coriolus Versicolor). It is a natural mushroom grown in forests located atop high altitude mountains, free from pollution. A proprietary production method, involving multiple levels of grinding and extraction, is employed to break down the rigid cell walls of Coriolus Versicolor to maximize the release of its active constituents. The extracted active constituents are then further purified by a special precipitation technique and standardized to 60% polysaccharides. This technique results in the highest concentration of polysaccharides compared to all commercial Coriolus Versicolor products available.

YZ Polysac — How is it made?

The overall sourcing and logistic process of the YZ Polysac material are strictly followed under Japanese quality assurance. YZ Polysac is carefully formulated by a select team of high-caliber medical doctors, nutritionists, and natural products experts. YZ Polysac is specially encapsulated in VegeCap, free of any animal ingredients. Each 450mg YZ Polysac capsule contains highly concentrated Coriolus Versicolor extract equivalent to 6750mg dry fruit-body of Yun Zhi mushroom. YZ Polysac is individually blister packed and boxed for ultimate product protection and convenient use.

What are the benefits?

When taken regularly, YZ Polysac can enhance the immune function, promote good health, and improve liver function as well as support longevity.

Japanese logistics and quality assurance and convenient packaging

What are the ingredients?

YZ Polysac® is a mushroom essence derived from 100% pure fruit-body of wild Yun Zhi (Coriolus Versicolor) mushroom. Yun Zhi mushroom has been used in traditional Chinese medicine for centuries as a rich source of antioxidants for the body.

Traditional and Complementary Uses

Coriolus Versicolor is commonly found year-round on dead logs, stumps, tree trunks, and branches. The fungus grows throughout the temperate forest zones of Asia, Europe, and North America. The mushroom belongs to the family of Bisidiomycotinae. Among the medicinal mushrooms used in traditional oriental therapies, Coriolus Versicolor Extract is one of the best commercially established products available on the market and was systematically researched for use in cancer treatments1.

Immunomodulatory Effect

Coriolus Versicolor extract has been demonstrated to activate T lymphocytes, B lymphocytes, monocytes, macrophages, bone marrow cells, and
natural killer cells. It is shown to be capable of restoring normal functioning of certain depressed immunological responsiveness caused by tumor cells, chemotherapy or radiotherapy.

Anti-tumor Effect

Coriolus Versicolor extract has been demonstrated to control various carcinomas in experimental animals and humans. Its anticancer activity is
attributed not only to a direct cytotoxic effect but also to inhibition of proliferation of various cancers by inducing production of superoxide dismutase (SOD) and glutathione peroxidase.
