The maitake mushroom (Grifola frondosa), also known as “sheep’s head” or “hen of the woods,” is a polypore that grows at the bases of oak trees. In addition to its culinary versatility (one of my favorite choice edibles from the fungal kingdom), the maitake mushroom has been researched extensively for its nutritional and medicinal effects. Let’s take a look at the research:
Contents
Benefits
Vitamin D
All mushrooms contain a fungal cell membrane molecule known as ergosterol. Upon UV exposure, this compound is converted into ergocalciferol, or vitamin D2. Some mushrooms contain more vitamin D2 than others depending on the species, environmental conditions, and post-harvest treatment. Maitake mushrooms, at 100 grams of fresh material, have been shown to contain more than 2,000 IU of vitamin D2 when exposed to supplementary UV treatment.
To increase the vitamin D2 content of your mushrooms, place them gills-side-up under direct sunlight. Sliced mushrooms will yield even more vitamin D2, as this method increases surface area and allows more ergosterol to be exposed to sunlight.
Cancer
There is ample research suggesting that maitake mushrooms may play a role in the protection against various cancers, with one key compound gaining most of the attention. Known as D-Fraction, this polysaccharide has the ability to enhance certain immune system cells, such as macrophages, helper T cells, and cytotoxic T cells, which all work together to attack tumor cells.
In one clinical trial, D-Fraction was administered to cancer patients without the combined use of conventional therapies. As a result, metastatic tumor growth slowed down, tumor lab markers decreased, and natural killer cell activity increased (natural killer cells are immune system cells that play a role in inducing tumor cell death). These results were witnessed in all patients.
Other studies have shown that D-Fraction can induce cellular death (a process known as apoptosis) in human breast cancer cells and advanced renal-cell carcinoma cells. Additionally, D-Fraction has been shown to reduce bladder cancer cell growth and has been linked to bladder cancer disease remission.
Immune system
For many of the same reasons that maitake may help protect against cancer, it also plays a critical role in supporting immune system health. Maitake contains important polysaccharides which, as mentioned previously, help to enhance the activity of certain immune system cells, such as T cells, B cells, macrophages, and natural killer cells. Ultimately, polysaccharides from the maitake mushroom act as immune system regulators.
Additionally, many medicinal mushrooms are known for their immunomodulatory effects, and maitake is no exception. Immunomodulation is the process of enhancing, stabilizing, or depressing the immune system depending on circumstances. For example, stimulating the immune system is necessary in instances of viral or bacterial infection. Depressing the immune system may be desirable when experiencing the effects of autoimmune diseases. Beta-glucans from maitake mushrooms have been shown to play a key role in the immunomodulatory process.
Antioxidants
Oxidation is a natural process in the human body that, if left unchecked, can result in conditions such as atherosclerosis, diabetes, and Alzheimer’s disease (just to name a few). Antioxidants combat the process of oxidation, and can be produced internally as well as provided externally through the consumption of antioxidant-rich foods.

Administration of maitake mushroom, therefore, may be a unique approach to combating angiogenesis.
Antioxidants isolated from maitake mushroom have been shown to be effective against other reactive molecules found in our bodies, including the hydroxyl radical and the superoxide radical (13). These molecules may play a critical role in several diseases, such as hypertension, cardiovascular disease, and myocardial infarction. Consumption of maitake mushroom with its naturally occurring antioxidants, including its phenols, flavonoids, ascorbic acid, and α-tocopherol may be a wise strategy in protecting the body against diseases associated with oxidation.
