Shiitake extract concentrates the mushroom into a capsule that delivers a reliable amount of beta glucans and other polysaccharides such as lentinan. Unlike dried powder, the extract standardizes these compounds so each dose matches the label.
People take it once or twice daily with food for better absorption. The polysaccharides support normal immune function by gently nudging immune cell activity.
Do not use shiitake extract alongside immunosuppressive drugs without a doctors input. Those with autoimmune conditions, diabetes, or bleeding disorders, as well as anyone on blood thinners, should check with a healthcare provider first. Safety during pregnancy and breastfeeding has not been established.
