Maitake
Grifola frondosa
Immune and metabolic positioning — beta-glucan D-fraction with preliminary human immune evidence.
What the evidence shows
Maitake ('hen of the woods') is a culinary mushroom with a well-studied beta-glucan fraction. A Phase I/II trial in breast-cancer patients found its D-fraction modulated immune parameters in a dose-dependent way without dose-limiting toxicity, and preclinical work consistently shows immune activation (macrophages, NK cells). Blood-sugar and lipid benefits are more preliminary — largely animal data on the SX-fraction, with limited human confirmation. The strongest signal is immune modulation; metabolic claims should stay cautious.
NutraLabel summarizes published research for formulation planning only. We make no health, disease, or efficacy claims about finished products.
Active compounds
Beta-glucans, notably the D-fraction and SX-fraction (protein-bound 1,3/1,6 beta-glucans)
Primary positioning angle: immune support, blood-sugar/metabolic health.
Format fit & formulation notes
Maitake is milder and more earthy than shiitake, but still savory — capsules are the most natural supplement format, with gummies possible given flavor masking. Chocolate is a stretch for a savory mushroom. Beta-glucan standardization (D-fraction content) is the key formulation lever; we match extract spec to your label and positioning.
Typical dose range (as studied)
Extract products commonly use ~500–1,000 mg/day of standardized beta-glucan extract; maitake is also eaten as food. Reference ranges for formulation, not a prescription.
Cautions
May lower blood sugar — caution for customers on diabetes medication. Theoretical blood-pressure and blood-thinning effects. Generally well tolerated as a food.
Claims defensibility
Immune-support language is the most defensible; blood-sugar and metabolic claims rest mainly on animal data and need conservative, hedged wording with regulatory review.
General immune-support structure-function language and beta-glucan-rich positioning, with substantiation.
Diabetes or blood-sugar treatment claims, cancer/tumor claims, and firm metabolic-disease benefit claims.
These are general guides, not legal advice. See our quality & compliance overview and work with your regulatory advisor before finalizing label copy.

Questions, answered.
Is maitake better in capsules or gummies?
Maitake is savory, so capsules are the most natural supplement format. Gummies are possible with flavor masking; chocolate is a stretch. We'll recommend the format that fits your dose and positioning honestly.
What's the evidence for maitake and blood sugar?
Mostly animal data on the SX-fraction, with limited human confirmation. Immune modulation has a stronger (still preliminary) human signal. Blood-sugar positioning should be cautious and regulatory-reviewed.
What is maitake D-fraction?
A protein-bound beta-glucan fraction studied for immune modulation. Standardizing D-fraction (beta-glucan) content is the main formulation lever for a maitake product's potency and label.
Can NutraLabel make a private-label maitake product?
Yes — capsules or gummies under your brand. Share your extract spec, dose target, and positioning; we develop the formula and manufacture finished goods.
