Maitake Mushroom Fruiting Body Extract
Also known as: Grifola frondosa, Maitake mushroom, Maitako, Dancing mushroom
Overview
Maitake mushroom (*Grifola frondosa*) is an edible and medicinal fungus found in Japan, China, and North America, often growing at the base of oak, elm, or maple trees. It is valued for its potential health benefits, including anticancer, antidiabetic, antimicrobial, antioxidant, anti-obesity, and immunomodulatory effects. Maitake is rich in β-glucans, antioxidants, vitamins B and C, copper, potassium, fiber, minerals, and amino acids. Research suggests that Maitake extracts, particularly D-Fraction, may reduce tumor size and stimulate the immune system. It has also shown promise in improving insulin resistance and inducing ovulation in patients with polycystic ovary syndrome (PCOS). While preclinical and some clinical research supports these benefits, more rigorous human studies are needed to confirm its efficacy and safety. The quality of available evidence is largely based on animal studies and some human trials, indicating the need for further clinical validation.
Benefits
Maitake mushroom extracts have demonstrated several potential health benefits. Studies indicate antitumor effects, with Maitake D-Fraction showing a reduction in tumor size and prevention of oncogenesis in animal models. Immunomodulatory effects have also been observed, with human studies showing a decrease in pro-inflammatory cytokines after ingestion of Maitake extracts. Furthermore, Maitake extract has been found to improve insulin resistance and induce ovulation in patients with PCOS, particularly when combined with clomiphene citrate. Animal studies suggest potential cardiovascular benefits, such as lowering triglyceride and cholesterol levels. These benefits are supported by varying degrees of evidence, with antitumor and immunomodulatory effects having stronger preclinical support, while PCOS and cardiovascular benefits require further clinical validation.
How it works
Maitake extracts, particularly β-glucans, exert their effects by interacting with the immune system. These β-glucans bind to cell wall receptors on immune cells, such as macrophages and T cells, stimulating specific immune responses. This interaction leads to the activation of macrophages and the production of cytokines, modulating the immune system and reducing inflammation. Additionally, Maitake extracts influence metabolic pathways, improving insulin sensitivity and lipid metabolism. The bioavailability of Maitake extracts can vary depending on the form and preparation, with different solvents affecting the molecular weight and, consequently, the bioavailability of the β-glucans.
Side effects
Maitake mushroom is generally considered safe, but comprehensive human studies are needed to fully assess long-term safety. Common side effects in humans are not well-documented, but animal studies and some human trials have not reported significant adverse effects. There is limited evidence on uncommon or rare side effects. Potential drug interactions may occur with drugs metabolized by cytochrome P450 enzymes, although this has not been reported in humans. Caution should be exercised in patients with immune system disorders or those taking immunosuppressive drugs. Pregnant or breastfeeding women should consult their healthcare provider before using Maitake supplements due to the lack of specific studies in these populations. It is important to consult with a healthcare provider before starting any new supplement regimen.
Dosage
The minimum effective dose of Maitake mushroom in humans is not well-established, but studies suggest doses ranging from a few milligrams to several grams per day may be effective. For antitumor effects, a dose of 5 mg/kg per day of Maitake D-Fraction Pro4X has been effective in animal studies. Doses used in human studies for immunomodulatory effects have varied widely. There is no established maximum safe dose, but high doses have not been associated with significant adverse effects in available studies. Consistent daily dosing is common, and the timing of administration can vary depending on the intended benefit. Maitake D-Fraction, an extract rich in β-glucans, is often recommended. Bioavailability can be influenced by the solvent used and the form of the extract. A balanced diet and adequate hydration may enhance absorption.
