Oriveda's P50 is a concentrated premium mushroom extract that supports the immune system.*
Trametes versicolor (also known under the names Coriolus versicolor, Yun Zhi, Kawaratake and Turkey Tail) is the most intensively researched and best documented mushroom in the world, due to its outstanding properties.

In Turkey Tail the marker compounds are beta-glucans (2 different types) and polyphenols (anti-oxidants). These should always be specified on the label. Since there are no noteworthy alcohol-soluble marker compounds present, a hot water extract is the best and most potent option. There is no need for dual or alcohol extraction.

Oriveda's P50 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 Oriveda's extract, having the highest level of the desired bioactives. Our objective lab reports confirm the purity and potency of this extract.

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.)

Strong Immune & Microbiome Support Stack: Oriveda Turkey Tail or ABM and Lion's Mane UTAMA

Uncompromising Quality Control and Laboratory Testing
Safety and transparency are critical when choosing a supplement. Every batch of Oriveda Mushroom Extracts undergoes rigorous, verifiable testing to guarantee absolute safety and therapeutic potency:

  • Verified Bioactives: Potency claims are backed by objective chemical analysis, confirming precise percentages of active beta-glucans and mushroom-specific marker compounds.
  • Independent Third-Party Audits: Testing is performed exclusively by independent, ISO/IEC 17025 accredited laboratories like Eurofins and Alkemist—never in-house.
  • Pure & Filler-Free: Strict testing ensures the extracts are 100% pure mushroom, entirely free from cheap starch, grain biomass, or hidden fillers.
  • Contaminant Screening: Every batch is thoroughly screened to guarantee it is completely free from pesticides, heavy metals, and microbial pathogens.
  • Public Domain Transparency: In an industry where many brands obscure data, Oriveda publicizes its Certificates of Analysis (COAs), making the official lab results fully accessible for verification.

Reviewer: Laura from Florida  
Been giving my dog 10 of these a day since the beginning of May as recommended by my veterinarian. He is also on Yunnan Baio.  He has hemangiosarcoma’s and my Vet said this would help keep things under control and prolong his quality of life. So far so good.
