Our partner supplier strives to use traditional extraction methods that best optimize the properties of each mushroom. They avoid the use of harmful solvents and chemicals which are common to many commercial extracts. Clean extraction methods are tailored to each ingredient, with a focus on preserving the maximal amount of nutrients and bioactives from each mushroom. Cold-processing also allows compounds that might be destroyed by heat to flourish. This combined attention to quality and detail assures that you get the full benefits of each mushroom in our formula.
