Fans at the foot
of an oak.
A single cluster can weigh several kilos: dozens of grey-brown, spoon-shaped caps overlapping into something between a feather duster and a cabbage. The fruiting bodies carry beta-glucans and the glucan-protein complexes known in the literature as the D and MD fractions. Ours is the fruiting body only, extracted 10:1, in an HPMC capsule.

One ingredient. One of the most studied culinary mushrooms, for every day, all year. Individual experience varies.
The fourth jar
on the shelf.
People arrive at maitake after the obvious three. Ask what they were looking for:
- A named species, for ‘mushroom blend’.
- Fruiting body, for mycelium grown on grain.
- 1,000 mg a day, for 100 mg in a four-mushroom capsule.
- A plain label, for a vague one.
The everyday choice for anyone who reads the label first.

Questions, answered.
Every day, all year, often alongside the others in the range.
Names given in the literature to particular glucan-protein complexes isolated from Grifola frondosa. They describe compounds found in the mushroom.
Maitake itself is a culinary mushroom and dried maitake is used as a seasoning. This is a 10:1 extract rather than the dried mushroom, so it is made for a capsule, not a pan. The powder is the one that goes into food.
Fruiting body, extracted 10:1. No grain in the jar.
Thirty days, at two capsules a day.
Yes. Fungal extract, HPMC shell.
Anyone pregnant or breastfeeding, and anyone under 18, should speak to a doctor first. If you take medication for blood sugar, mention it to your pharmacist.
