Mushrooms in Immune Assist

Adaptogenic mushrooms like those included in Immune Assist are specifically selected for their ability to aid the body in boosting its immune capacity while mitigating the effects of stress, fatigue, and adrenal burnout. Immune Assist fits all specialty dietary lifestyles as well (yes, keto and paleo, too)!

Reishi (Ganoderma Lucidum)

Reishi is a bitter, hard mushroom that is used to enhance longevity and better health in traditional Chinese medicine. Studies suggest that Reishi can mediate allergies, liver diseases, lung problems, diabetes, cancer, heart disease and other illnesses. It is also used among patients who are undergoing radiation and chemotherapy for pain reduction.

Cordyceps (Cordyceps Sinensis)

Cordyceps Sinensis has been used for approximately 50 years by the European military to increase and sustain soldiers’ energy. This medicinal mushroom is common throughout Chinese and Tibetan history, used as food, medicine and in spiritual mushroom rituals since at least 5000 BC.

Maitake (Grifola Frondosa)

Sometimes called the “hen of the woods”, maitake is a major culinary mushroom used in Japan. Researchers have indicated that this mushroom has the ability to regulate blood pressure, glucose, insulin, and both serum and liver lipids, such as triglycerides and cholesterol, and that it may also be useful in weight loss.


Shiitake, the incredible edible mushroom indigenous to East Asia, has long been used in Chinese medicine to promote youth and longevity. Shiitake contains the polysaccharide lentinan, which research suggests has potential anticancer effects by helping inhibit the replication of pathogens.


Chaga mushrooms, found growing naturally on birch trees in the Northern Hemisphere, have been used for centuries in folk remedies. Chaga has been shown to promote mental clarity, learning and memory. Chaga has been studied in cancer therapy, and its compounds are believed to kill cancer cells while boosting the immune system.

Turkey Tail (Trametes Versicolor)

Turkey Tail, has been a component of traditional Asian medicine for centuries. It contains two substances that are currently being studied as possible complementary cancer treatments in the US; in the 1980s, the Japanese government approved the use of one of those substances for treating several types of cancer.

Lion's Mane (Hericium Erinaceus)

Research on Lion’s Mane has shown the presence of several medicinal substances and antioxidants including palmitic acid, threitol and d-arabinitol. These substances have been found to reduce blood sugar and regulate lipid levels in the blood.

Poria Cocos

Poria Cocos has been used in ancient Chinese and Japanese medicine for thousands of years. Notable effects include calming the mind, promoting digestion, and functioning as a diuretic. Poria Cocos is a key source of pachymic acid, which recent studies have shown to be beneficial in treating pancreatic cancer.

Agaricus Blazei

Also known as Murrill or God’s Mushroom, it native to Brazil and widely cultivated in Japan for its medicinal uses. It is considered one of the most important edible, culinary and medicinal species of mushrooms known today. Traditionally, it has been used to help treat many common diseases such as atherosclerosis, hepatitis, diabetes, dermatitis and cancer.

TedMed Talk By Paul Stamets

View the TedMed talk where a mushroom biologist talks about the antimicrobial properties of fungi, how they can be used as potent insecticides, and how they may help boost the human immune system.

Fantastic Fungi

Fantastic Fungi, a film by Louie Schwartzberg, explores the power, beauty, and complexity of the fungi kingdom. Fungi have much more to offer than you know—from food and medicine to bioremediation, neurogenesis, and treating end-of-life anxiety. And that’s just tip of the iceberg.
