What is Maitake Mushroom?

The Maitake mushroom, or Grifola frondosa, carries a rich history in Japanese culture and is celebrated for its health benefits and esteemed status.

Beyond adding flavor to meals, Maitake is recognized for its medicinal properties, ranking it among the elite medicinal mushrooms globally. It functions as an adaptogen, supporting the body in managing stress and restoring balance.

Naturally found in Japan, China, and North America, these mushrooms thrive at the base of Oak, Elm, and Maple trees. While they can be grown domestically, wild Maitake are often considered superior. They are most commonly harvested in autumn.

Nutritional Value

Maitake is celebrated for its taste in the culinary world and for being a functional food packed with essential nutrients. So, what makes this mushroom a nutritional powerhouse?

Maitake is rich in vital nutrients, including [1]:

  • Vitamins: It's an excellent source of vitamin C, which is crucial for maintaining skin health, boosting immunity, and aiding in collagen production. Additionally, maitake mushrooms are among the top sources of vitamin D found in mushrooms, essential for bone health and immune function.
  • Minerals: These mushrooms are packed with minerals essential for bone strength, metabolic processes, and generating energy.
  • Fiber: Maitake contains dietary fiber, which is beneficial for digestion and promotes a healthy gut, pivotal for overall digestive wellness.
  • Amino Acids: As the building blocks of proteins, the amino acids in maitake are essential for muscle repair, facilitating enzymatic reactions, and supporting various bodily functions.

Now, let's examine some of Maitake's benefits more closely.

1. Boosting Memory and Cognition

The Maitake mushroom has shown great promise for brain health, especially in enhancing thinking and protecting against memory diseases [2].

Research in 2019 [3] explored how Maitake mushroom extract could help with learning and memory. They found that this extract effectively improved these functions. This improvement is partly thanks to the mushroom's effect on the hippocampus, a brain area crucial for memory. The study points out that Maitake might do this by increasing the levels of two pivotal brain substances:

  • BDNF (Brain-Derived Neurotrophic Factor): This protein helps brain cells grow, stay healthy and communicate. It's essential for learning and remembering things.
  • AMPAR (α-Amino-3-Hydroxy-5-Methyl-4-Isoxazolepropionic Acid Receptor): These receptors help brain cells communicate quickly and are vital for brain plasticity, which is the brain's ability to change and adapt, essential for learning and forming memories.

The study also highlights Maitake's potential to protect the brain, a significant finding considering the increase in neurodegenerative diseases like Alzheimer's. Maitake helps by preventing damage to brain cells in the hippocampus and supporting important brain signaling pathways.

The magic behind Maitake's benefits for the brain involves several actions. It modifies how brain cells signal to each other, protects against oxidative stress, and boosts neurotrophic factors like BDNF. The boost in BDNF is crucial for neuroplasticity, allowing the brain to make new connections. The increase in AMPAR expression is essential for synaptic transmission and plasticity, fundamental processes for learning and memory [4].

The implications of this research are vast. Maitake could enhance cognitive function in healthy individuals and as a complementary approach to treating or managing conditions associated with cognitive decline. This effect is particularly relevant for aging populations and those at risk of neurodegenerative diseases.

2. Enhancing Immunity

Beta-glucans are at the heart of Maitake mushrooms' power to boost our immune system. They are complex sugars located in the mushroom's cell walls and are Maitake's "secret weapon" for supporting our immunity [5].

Beta-glucans work by changing how our immune system reacts to threats. They kickstart immune cells like macrophages and T-cells into action. Macrophages are a kind of white blood cell that eat up and break down things like dead cells, germs, and other harmful substances that don't belong in our body. They're vital for our body's first reaction to infections. T-cells, meanwhile, are crucial for the next phase of defense, recognizing and remembering specific germs to fight off infections and destroy infected cells [6].

Studies on Maitake have found that its beta-glucans ramp up the activity of these pivotal immune cells. One specific study looked into how different extracts from Maitake can strengthen our innate immunity, which is our body's immediate response to invaders. The study found that an extract from Maitake using hot water was especially good at encouraging cytokine production and making human immune cells more effective at engulfing and killing invaders [7].

These findings suggest that the small polysaccharides, a type of sugar molecule from Maitake, can improve our body's innate immunity in lab settings, showing its potential as an immune system booster.

3. Managing Blood Sugar and Blood Pressure

Maitake mushrooms have sparked excitement among researchers for their potential to positively influence blood sugar and insulin levels.

Imagine a natural ingredient that tackles insulin resistance and high blood pressure, two common health challenges. Maitake mushroom steps into this role with its ether-soluble (ES) fraction showcasing a knack for lowering blood pressure in subjects with a tendency towards hypertension.

But that's not all – the whole mushroom powder and its water-soluble (WS) fraction have also been credited with reducing blood pressure in models of insulin resistance. The cherry on top? The ES fraction went further to cut down triglycerides and enhance markers of diabetes health, such as reducing circulating insulin levels and HbA1C, a long-term blood sugar marker. These findings paint a promising picture of Maitake as a multifaceted ally in metabolic health [8].

In another exploration, a part of Maitake known as fraction SX emerged as a hero in managing blood sugar and pressure. This fraction lowered glucose levels and improved insulin sensitivity, making it a potential game-changer for type-1 diabetes, especially when paired with chromium [9]. This fact suggests Maitake SX could be a valuable tool in the dietary management of diabetes and hypertension, offering a natural solution to these widespread concerns.

The journey doesn't end there. Maitake extracts, particularly fractions SX and D, have shown potential in addressing age-related hypertension and metabolic issues. These extracts not only enhanced insulin sensitivity but also dialed down inflammation markers [10].

This positions Maitake as a potential natural intervention for extending a healthier lifespan, mitigating the metabolic shifts that come with aging, and keeping glucose metabolism in check.

4. Promoting Fertility

Polycystic ovarian syndrome (PCOS) is a condition where the ovaries produce too many male hormones, leading to issues like small cysts on the ovaries, acne, weight gain, and infertility. But, there's a glimmer of hope from an unexpected source – Maitake mushrooms.

Recent research, particularly a fascinating 2010 study shines a light on this possibility. The study discovered that Maitake extract could kickstart ovulation in 77% of participants with PCOS, showing promise nearly on par with some traditional medications [11].

This Tokyo study is a beacon of hope for women struggling with PCOS. It evaluated the effects of Maitake extract on ovulation and found that an impressive 76.9% of participants saw their ovulation triggered by the extract. This success rate is particularly noteworthy given the stubborn nature of PCOS and the difficulties it presents in managing fertility issues.

Safety and Side Effects

Maitake mushrooms are generally easy to digest unless they’re less fresh, which can make them harder to break down. Cooking the mushrooms can help make them more digestible.

While it's rare, some people might experience an allergic reaction or an upset stomach after eating maitake mushrooms.

If you're managing diabetes, it's wise to speak with your healthcare provider before adding maitake mushrooms to your diet, as they could impact your blood sugar levels.

For those who are pregnant, breastfeeding, or living with an autoimmune disease, getting a green light from your doctor before using maitake mushrooms is advised.


Maitake mushrooms are a powerhouse of health benefits, revered in culinary and medicinal circles. They boost cognition, promote immune health, and assist in managing blood sugar.

Rich in vitamins, minerals, and antioxidants, Maitake offers a holistic approach to well-being and is a valuable addition to a health-conscious lifestyle. With their blend of flavor and function, Maitake mushrooms encapsulate the essence of nutritional richness and therapeutic potential.
