Shipping & Returns

Shipping Policy

Delivery Time

At O2 Worldwide we strive to ship orders immediately – normally within 1-2 business days of processing an order, so you can expect to receive your order within 3-6 business days (depending on your location).  Please note that we do not ship on weekends or holidays.  Also, please allow more time if you are outside the continental USA. 

International Shipping Terms and Restrictions                    

By ordering from us you agree to these terms.  You are advised to contact your country's customs office to thoroughly inquire about import regulations before placing your order, as we will not be liable for packages refused or held for delivery.  As the buyer, you are solely responsible for any import restrictions, prohibited import items, taxes, tariffs, fees, other duties, brokerage, and/or delivery fees applied to international shipments.  Some countries have shipping restrictions on certain products, contents, or products containing certain ingredients.  As the buyer, you are responsible for complying with all applicable international, national, and local laws regulating importation of products that you purchase.  If your order is refused delivery by your country's customs office due to unauthorized product, contents, and/or ingredients, O2 Worldwide is not responsible for any losses or costs incurred by you, the buyer.  If the shipment is abandoned or discarded by customs, you will not receive a refund or credit of any kind.  Also, some countries restrict imported supplements to a 90-day supply and must be for your own personal use; losses incurred due to exceeding your country's limitations will not be refunded. International shipping charges are non-refundable. Please be aware that getting a supplement approved for import often requires extensive, well documented official permits in advanced and not guaranteed to be approved by the other country's customs office.  Thank you for your understanding.


Return Policy

30 Day Money Back Guarantee

At O2 Worldwide we want you to be completely satisfied with your decision to try our products.  For that reason, we provide a 30 day Money Back Guarantee on all our products.  That’s how confident we are that you will be pleased with your results.  But if you are unhappy with a product for any reason, you can return the product within 30 days of purchase for a full refund of the purchase price excluding shipping and handling.  No questions asked.  Simply follow the instructions below.

Instructions for Returns and Refunds

To obtain your refund, you must first contact Support Services via your O2 Worldwide Back Office, by email at, or by phone at (385) 715-2519 (Monday–Friday 9am-5pm MST) in order to obtain an authorized Return Merchandise Authorization (RMA) number. We cannot accept any returns without an RMA number. (To expedite the process, please be ready with the order number from your packing slip.)

To receive a refund, you must postmark your return within 30 days of purchase. Be sure to clearly print the Return Merchandise Authorization (RMA) number on the outside of return package. Our shipping department is NOT allowed to accept packages without an approved RMA on the outside of the package.

Address return packages to: O2 Worldwide, Attn: RMA# ______, 1485 West Hill Field Road #202, Layton, Utah 84041, USA. We will not accept or issue a refund for any packages marked “return to sender” or “refused”. We will not accept C.O.D. returns. You, as the buyer, are responsible for all costs related to shipping back your item and that the item arrives to us without damage.  Return shipping charges will not be compensated for unless the return is a result of our error (i.e., you received an incorrect or defective item).  Packages being returned should be insured by you for your protection.  If you return a package, we recommend that you obtain proof of shipment. In order to qualify for a refund, you must return all full or empty containers of the product.

After our shipping department receives your return, it generally takes 3-5 business days to process your refund. Once a return is processed, it can take up to one billing cycle for this return to be posted to your account, depending on your financial institution. Refunds will be issued to the same credit card that was charged when ordering the product.

Start feeling great again.
