From treating diabetes and obesity to fighting cancer, maitake is exceptionally beneficial. However, to enjoy these benefits of maitake mushrooms, you need to use maitake at the proper dosage. For this reason, this article will explore the benefits, side effects, and dosage of the maitake mushroom. 

By the time you reach the end of this detailed guide, you should know how the ingredients in the maitake mushroom supplement can change your life. Are you ready? Let's start by figuring out what maitake mushroom is. 

What Is Maitake Mushroom?

Maitake mushroom, or Grifola frondosa in Latin, is an edible mushroom with both nutritional and medicinal properties. The mushroom grows in dying or dead hardwood trees, particularly maples and oaks.

It is a very distinct-looking tan-brown-to-gray mushroom. Also known as hen-of-the-woods, the cluster of mushrooms resembles the ruffled feathers of a hen sitting in the forest.   

Maitake mushrooms are native to the temperate forest of Europe, the eastern part of North America, and China, typically found from late summer to early autumn.

The word maitake means "dancing mushroom"(1) in Japanese. According to folklore, the name resulted from people dancing when they found the mushroom.

Maitake is a major culinary mushroom in Japan and China, where it has been consumed for many centuries.  It is held in high regard, even used as currency in the Japanese feudal era.

In the last 30 years, much scientific research has focused on Maitake mushrooms' benefits. This article will explore up-to-date Maitake mushroom health benefits, its uses, how to consume it, and if it has any side effects.

What Are The Health Benefits Of Maitake Mushrooms?

What Are The Health Benefits Of Maitake Mushrooms?

Maitake mushrooms can treat:

  • High blood pressure
  • Diabetes
  • Obesity
  • High blood cholesterol
  • Cancer and side effects of chemotherapy

Hen-of-the-woods mushroom's main component is the polysaccharide beta-glucan. Other bioactive ingredients like polysaccharide fractions (D, MD, MZ, and X) are also present in the mushroom. Additionally, maitake is a good source of carbohydrates, proteins, dietary fibers, vitamin D, and minerals (potassium, phosphorus, Magnesium, Calcium, and Sodium).

The different bioactive compounds isolated from the mushroom are attributed to the following Maitake mushrooms benefits:

1. Maitake Supercharges Your Immune System

Our body's immune system needs the right balance to function correctly. Maitake mushrooms can regulate the immune system. 

Many studies have examined the ability of Maitake mushroom extract to modulate immune responses(2). Scientific evidence shows that Maitake mushrooms can alter the immune system's response to any threat. The body can fight threats and diseases more efficiently with an improved immune response.

Beta-glucans—one of the major components or ingredients in maitake extract—are found to significantly stimulate defense reactions in the body(3). They are considered activators of immune responses and have been highly sought-after immune-boosting natural products throughout human history.

The D fraction of the Maitake mushroom activates the Natural Killer (NK) cells(4).NK cells control several types of microbial infections by preventing their spread and subsequent tissue damage.

NK cells also limit or exacerbate immune responses according to the body's needs. The stimulation of NK cells by Grifola frondosa extracts also plays an essential role in fighting off other foreign substances from the body, including cancerous cells—this gives maitake the cancer-fighting and prevention benefits.  As part of the maitake mushroom benefit, the Natural Killer cells also hold the potential to control autoimmune disorders.

To further boost your immunity and positive reaction towards disease-causing organisms, maitake extract activates macrophages and neutrophils(5), two white blood cells that devour microorganisms. They also lead to the production of cytokines(6). These are substances secreted by cells of the immune system which control the growth and activity of immune cells.

2. Helps Control Inflammation

Maitake mushrooms inhibit two significant inflammation mediators (TNF and interleukin).

The maitake's stimulatory actions on macrophages also play a crucial role in the control of inflammation. Macrophages are indispensable players in(7) inflammation and can regulate inflammation after destroying harmful substances. They also help in wound healing and maintaining homeostasis in the tissue following an injury.

Rheumatoid arthritis is a prolonged inflammatory condition in which the immune system attacks the joint. It leads to significant joint pain and inflammation and is a source of great distress to many people.

Agaroglycerides and ergosterol are two major anti-inflammatory compounds(8) that have beneficial effects against pain and inflammation in animal models. The finding of the 2012 study indicates that the anti-inflammatory and anti-nociceptive effects of the maitake mushroom can be utilized as an alternative medication for inflammatory pain.

Another study reported that the mycelium of the Maitake mushroom inhibits cyclooxygenase(9) (COX). Inhibition of COX is one of the mechanisms by which non-steroidal anti-inflammatory agents (NSAIDs) exert their potent anti-inflammatory and analgesic effects.

Grifola frondosa extracts have shown a significant reduction in inflammatory markers(10) even in healthy people given daily for just 12 days.

According to a research study conducted in 2019(11), if the underlying cause of the inflammation doesn't go away or specific control systems meant to stop the process fail to function, the inflammation may become chronic. 

Chronic inflammatory responses can lead to cell proliferation and mutation, frequently fostering the conditions for cancer growth. Using maitake reduces chronic inflammation and lowers the risk of tumor development and growth. 

3. Keeps Blood Sugar Levels Under Control

Keeps Blood Sugar Levels Under Control

Maitake mushroom has anti-diabetes effects, which have been reported in quite a few studies. Maitake mushrooms keep your blood sugar levels in the healthy range. 

In one study, the alpha glucan extracted from the fruiting body of maitake was given to animal models of type 2 diabetes(12)

Changes in body weight, levels of glucose in the blood, and the amount of glucose stored in the liver were noted. Following the administration of maitake, there was a significant decline in body weight and blood glucose levels. 

In many cases of type 2 diabetes, a significant factor for the increased blood sugar level is tissue resistance to insulin. Many anti-diabetes medications fail to achieve the expected levels of efficiency when there is insulin resistance. While some may be able to control blood sugar, they come with many potential side effects.

Grifola frondosa is a safe and natural alternative to treat insulin-resistant diabetes. Some reports suggest maitake may, to some extent, enhance insulin sensitivity(13) and weaken insulin resistance.

It is important to note that one of the leading causes of type 2 diabetes is obesity. An article published in 2017 by the National Library of Medicine(14) showed that obesity is the leading risk factor for type 2 diabetes. Luckily, maitake facilitates weight loss

4. Fights Malignant Cancer Cells

The active ingredients in maitake play a significant role in the fight against cancer. Polysaccharides in the mushroom show potent antitumor bioactivity during chemoprevention and treatment. 

Maitake mushrooms help people undergoing cancer treatment avoid the side effects of regular cancer treatment methods, including chemotherapy and radiotherapy. 

According to experts, this can be partly attributed to the modification in the gut microbiota composition following the ingestion of mushroom polysaccharides. These beneficial compounds can reverse alterations of bacterial species involved in tumor development(15). Controlling microbial dysbiosis can augment health-promoting bacteria and metabolites of the intestine.

Research shows that the glycoproteins extracted from the mycelium of Grifola frondosa fight cancer cells(16). Glycoproteins kill the tumor cells(17) by directly putting a brake on their proliferation or initiating tumor cell death.

The beta-glucans and MD fraction of maitake mushrooms also exhibit antitumor effects(18). These bioactive compounds activate cells of the immune system (such as macrophages and lymphocytes), which attack the tumor cells.

In 1999, the Food and drug administration (FDA) approved clinical studies using the D-fraction form of maitake.  This was used in people with advanced prostate and breast cancer. To date, the antitumor property of D-fraction(19) has been studied in cancers of the bladder, prostate, liver, white blood cells, brain, breast, and kidney with positive results.

5. Decreases Blood Pressure

Decreases Blood Pressure

Maitake mushrooms keep blood pressure levels in check. The blood pressure-lowering activity of the Maitake mushroom has been the focus of multiple studies.

In a study(20) on aging female rats, Maitake mushroom extracts reduced blood pressure after four months. There were no significant toxic changes in the blood with the intake of Maitake fractions. This indicates that maitake could be a safe and natural method to favorably influence the progressive elevation of blood pressure associated with aging.

Another study evaluated the effects of Shiitake mushrooms and Maitake mushrooms on blood pressure levels(21) in rats with hypertension. In a study conducted at Tohuku University in Japan, 18 rats were divided into three dietary groups.  The first group of rats received no mushrooms, the second received Shiitake, and the third group received Maitake powders.

The rats were fed salt-infused drinking water for nine weeks. The blood pressure and body weight of the rats fed with the mushrooms had significantly lower blood pressure.  It could be possible that the lower body weight of the rats, due to the mushroom diet, may have contributed to lowering blood pressure.

6. It Has Antiviral Properties

Grifola frondosa potentiates the host defense system and can exert a protective effect against many viruses that can cause diseases.

Maitake's health benefits in fighting off viruses have been reported in a 2007 study. An antiviral protein was extracted from Grifola frondosa that inhibited the replication of Herpes Simplex Virus type 1 (HSV-1)(22).  

In the study, the mushroom protein reduced the severity of HSV-1-induced inflammation of the eyelids (blepharitis) and stromal keratitis (a type of corneal inflammation that can cause vision loss or blindness) in animal models.

In another study, researchers examined the effectiveness of dietary maitake mushrooms in boosting the potency of influenza virus vaccination(23). This double-blind, placebo-controlled study on healthy adult volunteers analyzed the response to the influenza vaccine by measuring blood antibody levels. Participants were given maitake daily for 12 weeks and were also evaluated for the suppression of symptoms of the common cold.

The study found that continuously eating maitake mushrooms can raise antibody levels against the influenza virus. Additionally, symptoms of severe cold including nasal discharge and headache were significantly improved with the intake of Maitake mushroom.

7. Maitake Mushroom Extract Improves Gut Health

One of the few mushroom varieties that benefit the health of your gut, this mushroom that grows on elm trees provides amino acids and glucose tolerance to ensure you are not suffering from gut inflammation. Maitake mushroom benefits in colon inflammation have been evaluated in clinical research.

The polysaccharide extracts of Maitake mushrooms have shown a reduction in the inflammation associated with inflammatory bowel disease (IBD)(24). TNF alpha is one of the major chemicals involved in IBD. 

In a rat model with IBD, the mushroom inhibited colon ulcers, TNF alpha, and weight loss associated with the disease. Moreover, the clinical effect of Maitake mushroom was similar to a drug commonly used in the treatment of IBD. 

This study suggests that Maitake mushroom could be valuable medicinal food for IBD treatment. It could also be an effective alternative treatment modality.

A study evaluated 14 mushroom species, including maitake, in chronic gastritis(25) caused by Helicobacter pylori. The researchers found that the alcoholic extracts of the mushrooms inhibited the growth of H pylori. This effect of medicinal mushrooms can be potentially utilized in treating H-pylori-associated gastrointestinal disorders.

8. Lowers Cholesterol

One of the lesser-known benefits of Maitake mushrooms is that they can help control cholesterol levels. Whether you take the mushroom in supplement form or other forms, the health-promoting properties of the fungus will help you lower the bad cholesterol and, at the same time, increase the good cholesterol. 

Approved by the food and drug administration, Maitake mushrooms have meager amounts of total fat. One hundred grams of the mushroom contain just about 0.2 grams of fat. While helping you avoid unnecessary fat, maitake mushrooms can be added to soups to provide good fiber and beta-glucans that support losing cholesterol in the body. 

Incorporating maitake into your daily diet can significantly promote healthy weight loss and improve blood cholesterol levels.

Maitake mushrooms can also alter lipid metabolism(26) by inhibiting the elevation of blood lipid levels and liver fat accumulation.

The study from Tohuku University, Japan, also measured plasma cholesterol, triglyceride, and phospholipid levels. There was a significant reduction in the total cholesterol levels in the rats fed maitake. This lipid-lowering property of maitake could be attributed to increased cholesterol excretion or due to the inhibition of its synthesis.

Maitake mushrooms lowered cholesterol(27) in a rat model study. There was a reduction in total Cholesterol and VLDL cholesterol.  Similar effects were also seen in another clinical study where mice fed with cholesterol were given Maitake mushroom extracts.

9. Maitake Mushroom Benefits For Skin
