Beta-glucan content is the single most important criterion for evaluating a reishi extract. These branched-structure polysaccharides interact with specific receptors on the body’s defence cells. Raw whole-mushroom powder typically contains less than 0.1% of these compounds in bioavailable form — far too little for a meaningful effect. Dynveo’s extract reaches 70% beta-glucans thanks to a patented aqueous extraction process that concentrates the active compounds while removing non-essential by-products. These beta-glucans have at least 27 branch points and a molecular size calibrated for optimal interaction with cell receptors — a daily 200 mg dose is enough for a significant intake.

Reishi beta-glucans are recognised for supporting the normal functioning of the body’s defence system. Regular supplementation helps maintain balanced activity in the cells involved in natural protection, including macrophages, neutrophils and NK lymphocytes — particularly relevant during seasonal changes, periods of increased tiredness, or significant physical or psychological stress. Reishi also has recognised adaptogenic properties that help the body better manage periods of overload, making it a versatile supplement for active people seeking overall wellbeing support.

Unlike classic methods that use organic solvents, this patented process uses only water to extract and concentrate the polysaccharides and beta-glucans, resulting in an exceptionally pure, fully water-soluble extract with no chemical residues, reaching 70% beta-glucans — a level unreachable with conventional methods. The process also preserves the beta-glucans’ structural integrity, keeping their molecular size and branching at an optimal level for cell-receptor interaction, and full solubility supports fast, complete assimilation.

Dose: 200 mg of extract a day, one capsule with a meal and a glass of water — sufficient thanks to the extract’s exceptional concentration. Courses of 4 to 12 weeks are recommended, with a short break of a few days between monthly cycles to maintain the body’s responsiveness. Best taken in the morning or at midday. The capsules contain no irritating excipients and suit vegetarian and vegan diets. Store away from heat, humidity and light.

This food supplement is not a substitute for a varied, balanced diet and a healthy lifestyle. Do not exceed the recommended daily dose. Keep out of reach of young children. Pregnant or breastfeeding women should consult a healthcare professional before starting supplementation. People on immunosuppressant, anticoagulant or antihypertensive treatment should seek medical advice first. People allergic to mushrooms should avoid this product. In case of autoimmune disease, consult a doctor before use due to beta-glucans’ modulating action on natural defences.

How does this compare to raw reishi powder?

Raw reishi powder contains less than 0.1% bioavailable beta-glucans, while Dynveo’s concentrated extract contains up to 70% — thanks to the patented aqueous extraction process. In practice, 200 mg of this extract delivers as many active beta-glucans as several grams of raw powder.

Can reishi be taken long-term?

Reishi is traditionally used over long periods, though courses of 4–12 weeks with a short break between cycles are generally advised to maintain responsiveness. The purity of this excipient-free extract makes it well tolerated over time.

Is it suitable for vegetarians and vegans?

Yes — the capsules are made from hypromellose, a plant-based cellulose, and the formula contains only organic reishi extract and organic acacia fibre as a natural carrier. No animal-derived ingredients.
