Reishi mushrooms have long been utilized as part of traditional Eastern medicine to promote health and longevity, including immune system support. Reishi mushroom powder can also be added to drinks as an easy, healthy treat that contains antioxidants, polyphenols and carotenoids while being high in B vitamins.

Reishi mushroom contains antioxidants, polyphenols and carotenoids which contribute to its health benefits; other compounds that may add to these benefits include beta-glucans and triterpenoids which may help lower blood pressure and sugar levels. Reishi also stimulates white blood cells known to kill cancer cells; its anticancer effects have been documented among cancer patients; more research should be conducted to see whether it can provide benefits in healthy adults as well.

Reishi mushrooms are often ground into coffee as the go-to choice, due to its healthful constituents such as high concentrations of beta-glucans that support immune function and reduce stress levels, as well as providing energy boosts that lessen chronic fatigue symptoms.

Reishi can generally be tolerated well by most individuals; however, some may experience an upset stomach or dry mouth after taking large quantities. Reishi should not be taken during pregnancy or breastfeeding periods, by those with blood disorders, or those undergoing surgery; additionally it should not be combined with antidiabetic drugs as this could cause dramatic drops in blood sugar levels.
