Return Policy
Last Updated: May 12, 2026
At SF Zero, we want you to sleep better. If SF Zero Complete doesn't help you do that, we don't want to keep your money. This page explains your return rights, the procedure, conditions, and how our 30-night sleep guarantee works. By placing an order, you agree to the terms below and to our Terms and Conditions.
This Return & Refund Policy should be read in conjunction with our Terms and Conditions.
Return Period – 30 Days
SF Zero offers a voluntary 30-day return period from the date of delivery. During this period, you may request a return without providing a reason, unless otherwise required by applicable law.
Because SF Zero Complete is a consumable supplement, returns are only accepted if the bag is unopened and the safety seal is intact. This is a food safety and hygiene requirement. We cannot resell or accept back any product whose seal has been broken.
If your bag is opened and SF Zero Complete isn't working for you, the 30-Night Sleep Guarantee further down this page applies instead. You are covered either way.
30-Night Sleep Guarantee
We believe SF Zero Complete works. If it doesn't work for you, that is on us, not on you.
If you have used SF Zero Complete nightly for at least 14 nights and you don't notice a difference in your sleep, email us at support@sf-zero.com within 30 days of delivery. We will issue a full refund. Keep the bag. No need to ship anything back.
You only need to:
- Email us within 30 days of delivery
- Include your order number
- Tell us briefly what you experienced. This helps us improve the formula and is the only thing we ask in return
One refund per customer under the guarantee. Applies to first-time orders of SF Zero Complete.
