How long is a product potent after expiration?
A. We cannot guarantee product potency after expiration. There are too many variables involved that we do not have control over. However, here are a few guidelines to help you determine whether your product is still potent: For our Whole Herb formulas (caps, tea, extracts): If the product is kept securely closed and in a cool, dry environment, it may be potent for 1-2 years after the expiration date. For our Dr. Enzyme™ product: If the product is kept securely closed and in a cool, dry environment, it may be potent up to 1 year after its expiration date.
