In short, it means certain active constituents are concentrated 8-10x compared to a typical extract. Let’s use 8:1 as an example (like our Cordyceps powdered extract found in the LUNGS formula). Fruiting body is harvested, dried, and extracted in water and/or alcohol before being powdered. If you start with 1g of dried mushroom, and the powdered extract yields 1g, this is a 1:1 extract. If the same 1g of powdered extract was obtained from 8g of pre-extracted dried mushroom, we call it 8:1, representing an 8x concentration. With mushrooms, this process leads to lower levels of beta-glucans but much higher levels of other key constituents like terpenes, which is why we use concentrated extracts specifically for Lion’s mane, Reishi, and Cordyceps, depending on the formula.
