What is shiitake mushroom extract used for?

Shiitake has been cooked and used in traditional practice across East Asia for centuries, and the earliest written record of it goes back to the Song dynasty in 12th century China. It is best known for its polysaccharides, the beta glucans that mushroom extract labels are standardized to. Each capsule holds 500 mg of shiitake fruiting body extract standardized to 30% polysaccharides, and people usually take one to three a day with a meal.

How people use it

Take one to three capsules a day with a meal, and no more than 12 in a day. We suggest the morning or afternoon rather than right before bed. At one a day, a bottle of 90 lasts three months. The label says it is for adults only, so if you are pregnant or nursing, take medication or have a medical condition, ask your doctor first.

Fun fact: The name is Japanese. Take means mushroom, and shii is the Japanese chinquapin, an evergreen relative of the oak whose fallen logs shiitake has traditionally been grown on.
