The usual dose is 2 to 3 grams of dried, powdered turkey tail mushrooms three times per day, either mixed into food or put into capsules. Specialized extracts known as PSK or PSP (which focus on single polysaccharides in the mushroom, to the exclusion of all other potentially beneficial compounds) were the actual form of this mushroom studied and are given in the same amounts as powdered turkey tail.
However, these extracts are quite a bit more expensive than the whole powdered herb. Crude turkey tail mushroom has been used successfully in traditional medicine for thousands of years, so it is unlikely these special extracts must be used for it to be effective.
Turkey tail mushroom generally stays potent for many years, regardless of its form. The constituents don't break down easily. Keeping it away from heat and light will help extend its useful shelf life.
