Mushroom Supplements

People may use mushroom supplements as wellness tools to help manage stress. Some studies suggest that mushrooms may help reduce symptoms of anxiety and depression as well as improve a person’s general sense of well-being.

Mushroom supplements may also improve immune function, explains Dr. Kelvas. As a result, mushrooms are often used by individuals with medical conditions like cancer (consult the oncology team before taking any mushroom supplements). Studies have also shown mushroom supplements may be beneficial against viruses, such as COVID-19.

Types of Mushroom Supplements

Some of the most popular mushroom varieties used in supplements include:

  • Reishi (Ganoderma lucidum) has been used to treat conditions such as cancer, Alzheimer’s disease and diabetes, although more research is needed to determine reishi mushrooms’ efficacy in these treatments.
  • Turkey tail (Trametes versicolor or Coriolus versicolor) has been used to treat lung conditions in traditional Chinese medicine and is approved in Japan as an immune-boosting supplement to individuals undergoing cancer treatment. However, the Food and Drug Administration (FDA) hasn’t approved Turkey Tail as a treatment for cancer or any other medical condition.
  • Shiitake (Lentinula edodes) may protect against viral infections, such as COVID-19. A 2022 study in Food Chemistry Advances suggested that consuming shiitake mushrooms may be beneficial in the treatment of COVID-19, thanks to its antiviral, anti-inflammatory, and immunomodulatory properties.
  • Lion’s mane (Hericium erinaceus), may reduce symptoms of anxiety, depression and PTSD, by minimizing inflammation and by encouraging nerve growth, both of which influence mental health, according to Richardson. A 2021 study in the Journal of Food Biochemistry also suggests Lion’s mane may be an antioxidant with anticancer properties.
  • Cordyceps may have anti-cancer, anti-diabetic, anti-fatigue and anti-aging properties, based on results from pre-clinical studies, according to a 2021 study in Frontiers in Pharmacology.
  • Chaga (Inonotus obliquus) may help reduce swelling and inflammation and boost the immune system.
  • Agaricus blazei Murrill, commonly known as sun mushroom may enhance chemotherapy treatment and help reduce side effects of many conventional chemotherapy drugs.
