Immune Capsules
Capsules carry shiitake polysaccharides from the fruiting body as the immune-positioned dose.


Shiitake extract is made from the fruiting body of Lentinula edodes. The commercial marker is usually total polysaccharides, sometimes with a separate beta-glucan line. Lentinan, the purified beta-glucan studied in Japan, is a different material from a 10–50% polysaccharide powder.
It is used in immune-positioned capsules, mushroom coffee, broths and savoury snacks. The powder is brown to yellow and tastes savoury, so it suits a capsule or a seasoned food better than a clear drink.
When buying, name polysaccharides and beta-glucan separately, and ask which method produced each number. A UV polysaccharide result counts more than fungal beta-glucan. Fruiting body should be on the specification, not assumed.
