Coriolus Versicolor PSP-50 is a concentrated premium mushroom extract that supports the immune system.*
Coriolus versicolor (also known under the names Trametes versicolor, Yun Zhi, Kawaratake and Turkey Tail) is the most intensively researched and best documented mushroom in the world, due to its outstanding properties.

Oriveda PSP-50 is the most potent Coriolus PSP extract commercially available. It is also the only fully certified extract worldwide, with guaranteed levels of the main bio-active and bio-available ingredients. In Turkey Tail the main bioactive compounds are beta-glucans (2 different types) and polyphenols (anti-oxidants). Oriveda guarantees the presence of these compounds and their bioavailability.
Only the mycelia (the 'roots' of the mushroom) were used for the extract, having the highest level of bio-actives.
PSP is the abbreviation of PolySaccharo-­Peptide, a protein bound polysaccharide extracted from a specific strain of the mycelia of the Coriolus versicolor mushroom.

Extracted using hot water followed by alcohol precipitation - the main bioactives are water-solubles with a high molecular weight according to research. Alcohol precipitation is a purification process. It removes useless matter and low molecular weight compounds and thus increases the concentration of bioactives in the final product. The final product contains no alcohol.



Function:
Supports the immune system.

More Information

PSP is an abbreviation of 'PolySaccharoPeptide': now in general known as 'proteo-glycan'. ORIVeDA's PSP-50 is identical to the original PSP as it was developed in China, over 25 years ago. In itself PSP is an improved version of the well-known Japanese PSK, which is even older. PSP is chemically identical to but structurally different from the Japanese PSK (PolySaccharideKureha), which is marketed and sold under the brand name Krestin in Japan.

ORIVeDA's PSP-50 has been cultivated and extracted using the original methods. The only difference is a significant higher purity due to the more advanced 21st century pharmaceutical techniques. Only pure COV-1® mycelium (the 'roots' of the mushroom) was used for the extract, having the highest level of the desired bioactives.

The quality marker for hot water extracted Turkey Tail is beta-glucan. Turkey Tail contains two types of beta-glucan, which are in part linked to peptides to form bioactive glyco-proteins / proteoglycans. To be in line with the research a Turkey Tail extract should preferably be based on a specific deep layer cultivated mycelium strain (COV-1) of the mushroom. "Deep layer cultivated" means "cultivated in liquid" as opposed to rice/grains. The advantage is that there is no left-over substrate in the final product, it is pure mycelium, starch-free. This method is only used in Asia.

This product is similar in function (and with a higher PSP percentage) to the I'm Yunity supplement for dogs, (at a much more reasonable price.)
