What exactly is in each capsule, and why whole mushroom powder rather than an extract?

Each capsule contains whole chanterelle mushroom powder (Cantharellus cibarius). The powder is made from the entire fruiting body without isolating individual compounds from it, such as beta-glucans or proteins. As a result, the supplement retains the natural composition of the mushroom as it is found in food: nutritional components, flavour compounds and minor substances that remain together after drying. This is what sets whole mushroom powder apart from extracts in which a single active substance has been isolated: you get the mushroom in a form close to how it is used in cooking, but without having to cook it. The capsule also masks the distinctive mushroom taste, which some people find too strong, and lets you add this ingredient to your diet without changing the taste of your meals. Because the product is not an isolated extract, it is often chosen by people who want to include a natural food ingredient in their diet rather than a supplement based on a single substance.
