Refund Policy


Last updated: June 8, 2019



If you are not satisfied with your purchase for any reason, we will refund the amount paid for your first try, less shipping and handling. To request a refund, please send an email to with your name, order confirmation number, and reason for the request, within 60 days of receiving your first shipment. To prevent abuse of this policy, we retain the right to refuse or restrict this guarantee based on our discretion and best judgment.



We do our best to ensure your bottles travel safely, but occasionally accidents may happen in transit. If the product you received was damaged, please reach out and send a photo to us, and we will replace it for free.



We will do our best to address any changes to an order before it ships, but once packages enter processing, they cannot be canceled or modified. In these cases, orders may be eligible for a return.

Please send returns to:

WeWork c/o ZBiotics Company Returns
44 Montgomery St, 3rd floor
San Francisco, CA 94104

Please include your name, e-mail address, order number (if available), a copy of your paper invoice or a printed copy of your e-mail receipt, and the reason for return.




If you purchased ZBiotics on Amazon and you are not satisfied with the product, you must use or the Amazon app to return the items or request a refund. We cannot help facilitate these transactions because they are handled exclusively by Amazon.
