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:

Directions:
One serving is 3 capsules.
Recommended intake:
A leaflet with detailed instructions and background is included with every order.
As a daily dietary supplement: 1 serving daily (adult below the age of 50); 2 servings in case you're older.

In case you do not want to consume the capsules - they are easy to open (just pull them apart) and you can dissolve the extract powder that's inside in warm / hot water. We recommend to take the extract together with some vitamin C this improves the absorption and therefore the therapeutic potential. Store at room temperature, dark and dry.
Suggested for dogs:
100mg per kilogram of body weight per day, divided into morning/evening portions. 6-7 capsules daily for a 50# dog.
[ 50lb = approx 23kg x 100mg = 2300mg/ 350mg/cap = 6.57 caps per day ].

60 servings / 180 capsules @ 350 mg
General guidelines:
This product does not contain toxins, psychotropic substances or other harmful substances. It is not
addictive. It is not possible to overdose and there are no harmful side effects. In general it can be used
together with other medication and will not affect the intended effect of that medication.
The product should be taken with water or another liquid (not in smoothies!) together with food.
If immune support is the main goal, you should take the product on an empty stomach, at least 30 min. before meals.
If you do not want to consume the capsules: they are easy to open (just
pull them apart) and you can dissolve the extract powder that's inside
in warm water.
We recommend to take the extract together with some vitamin C this
improves the absorption of betaglucan in particular and therefore the
therapeutic potential.
Warnings:
Do not use when on immune-suppressing
medication, e.g. after an organ transplant. This extract's
immune-modulating
properties can act against the medication, so do not use this extract if you are
using this type of medicine.
Better NOT mix with lactose-containing
products such as milk lactose
will bind to the polyphenols,
rendering them useless.
For people that are highly susceptible to swings in blood sugar levels (usually the same people that have
problems with alcohol and caffeine): mushroom extracts can have an effect on blood sugar
levels. People using insulin (such as diabetics) might have to adjust their medication. There are reports
stating that taking mushroom extracts can cause of feeling of fatigue or dizziness in these cases
because blood sugar levels are too low. Taking the product together with some sugar-containing
beverage (such as freshly squeezed juice also
contains vitamin C (!)) might help.
Since the effect on pregnant and breastfeeding women has never been researched, we recommend
against using mushroom extracts in these situations.
General Cautions:
Keep away from children.
This product has not been evaluated by the FDA. It is not intended to diagnose, treat, cure, or prevent any disease.

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.)
