Return Policy

Any unopened bottle purchased directly from Houston Enzymes may be returned within 60 days of purchase for a full refund. Products are guaranteed to be active to the level stated on the label, within the stamped expiration date. Products purchased from other resellers, including Amazon, will need to be returned to those resellers in accordance to their own return/refund policy. Because we cannot guarantee specific results for your unique digestive needs, we offer free samples to residents in the US.
