Maitake, also known as Grifola frondosa, is native to Asia and the United States. Valued for centuries in wellbeing traditions, it is considered a natural tonic and a general support against everyday stress. This supplement comes exclusively from controlled organic cultivation in the United States, guaranteeing the absence of GMOs and chemical residues and a minimal environmental footprint. Slowly dried at low temperature then finely ground, the Maitake retains all its original active substances for optimal effectiveness with every dose.

Maitake’s main qualities lie in its high polysaccharide content, standardised to 60%, and its significant beta-glucan content of 20% — complex sugars known for their beneficial action on immunity. The extract used in these capsules offers all the advantages of a full-spectrum powder, meaning the whole phytochemical spectrum of the entire mushroom is preserved. Each capsule provides 300 mg of polysaccharides and 100 mg of assimilable beta-glucans, with no trace of additives or solvents.

The vegetable capsule format is the ideal choice for preserving the integrity of the Maitake. Unlike powders or tablets sensitive to humidity, the capsule perfectly isolates the active compounds from air and oxygen, ensuring optimal storage without risk of degradation of the precious molecules. This packaging suits vegan diets and allergy-prone individuals, as it contains no gluten, dairy derivatives or artificial colourings.

The recommended dose is 1 to 3 capsules per day, ideally in the morning with a large glass of water, to fully benefit from the synergistic action of the polysaccharides and beta-glucans over the following weeks. Thanks to its gentle, allergen-free formula, this supplement suits both vegetarians and people wanting to avoid controversial additives. Maitake can be combined with other complementary mushrooms such as shiitake or reishi, for a comprehensive approach to immune support.

Not recommended for pregnant or breastfeeding women without medical advice. Not recommended for people on immunosuppressant treatment without prior medical advice.

What makes concentrated Maitake capsules different from other forms?

The capsule format actively protects the fragile components against humidity and oxidation, unlike powder formats which quickly lose effectiveness. These capsules contain a complete full-spectrum extract with no solvent or additive, where each capsule equals a strong, intact and highly assimilable portion of mushroom.

Where is the Maitake in these capsules grown?

The Maitake comes exclusively from cultivation sites in the United States, guaranteed free from pesticides and genetic modification. Each harvest respects strict environmental standards and benefits from independent control ensuring the botanical authenticity of the mushroom used.
