How to create a return


To qualify for a refund, we require the thin KOS label that surrounds the product bottle to be returned along with your original order number and the return authorization (RA) number assigned to your return written on the outside of the envelope.

It is your obligation to pay the return postage, and we do recommend you opt for tracking and confirmation numbers for verification of delivery. Please note we are not asking you to mail back your entire supplement bottle, only the thin, product label surrounding the bottle. To return our new 14-serving pouches or single-serving pouch, simply empty the pouch and return in an envelope with your Return Authorization # (RA#) written on the front. We must receive the label(s) within 60 days from the date of original purchase for the refund to be valid.

If you need assistance with your return, you may also contact us at 1-833-344-4567 Monday through Friday between the hours of 9:00am and 5:00pm Pacific Time, or by emailing us at
