Maitake (Grifola frondosa)
Maitake — meaning 'dancing mushroom' in Japanese — contains D-fraction beta-glucans that are among the most potent immune-activating polysaccharides in the mushroom kingdom, studied specifically for their effects on natural killer cells and healthy glucose metabolism.
Key Compounds in Maitake
Maitake's primary active compounds are its unique D-fraction beta-glucans — a specific structural form of beta-1,6/1,3-glucans found in high concentrations in this species. D-fraction has been studied for its ability to activate NK cells, macrophages, and dendritic cells more effectively than beta-glucans from many other mushroom species. Maitake also contains alpha-glucan fractions, ergosterol (a vitamin D precursor), and a range of antioxidant phenolic compounds.
Historical Use of Maitake
Maitake grows in the wild in mountainous regions of northeastern Japan and North America, appearing at the base of oak, elm, and maple trees in the fall. In Japan, it has been traditionally foraged and consumed as a culinary and medicinal food for centuries, valued for its immune-supporting and energy-boosting properties. Its rarity and value in traditional Japanese culture reportedly caused people to 'dance with joy' upon finding it — hence the name.
Modern Research on Maitake
Research on Maitake's D-fraction has been conducted in both in vitro and human studies. A 2009 study published in the Journal of Medicinal Food found that Maitake D-fraction activated immune effector cells and demonstrated synergistic effects with other immune compounds. Research has also explored Maitake's effects on glycemic response — a 2012 study found Maitake extract influenced insulin sensitivity markers in animal models, with follow-up human research ongoing.
How NüShroom Uses Maitake
Maitake is part of both the Daily Defense Gummies 10-in-1 blend and the Fermented Superblend. Its D-fraction beta-glucans work synergistically with Turkey Tail's PSK/PSP and Chaga's polysaccharides to provide comprehensive immune system coverage from multiple biological mechanisms.

Standard doses in research range from 500mg to 2,000mg of Maitake extract daily. Maitake is well-tolerated with no significant adverse effects at supplemental doses. Those on diabetes medications should monitor blood sugar, as Maitake may have modest effects on glucose metabolism.
Maitake FAQ
What makes Maitake's beta-glucans unique?
Maitake contains D-fraction beta-glucans — a specific 1,6/1,3-glucan structure that research has shown to activate NK cells, macrophages, and dendritic cells with particular efficiency. While many mushrooms contain beta-glucans, the D-fraction from Maitake has a distinct molecular structure that interacts with immune receptors in ways that set it apart from other species.
Does Maitake affect blood sugar?
Research suggests Maitake may have modest effects on insulin sensitivity and glucose metabolism. While it's not a treatment for diabetes, some studies have found Maitake extract influences glycemic markers in animal models and preliminary human research. Those with diabetes or blood sugar conditions should consult a healthcare professional before supplementing with Maitake.
