Frequently Asked Questions

What is Quantum Nutrition Labs' return window?

Returns must be requested within 45 days of the invoice date, and a Return Authorization Number is required before sending anything back. No credit is given on items returned without that authorization number.

Does Quantum Nutrition Labs charge a restocking fee?

Yes, returns are subject to a 15% processing fee, and this applies even to unopened bottles returned in good condition. Third party, food, and lifestyle products are final sale and cannot be returned at all.

Can I return an opened bottle to Quantum Nutrition Labs?

First time customers may receive full credit on one opened bottle per product type for up to two different products if it is returned in good condition within 45 days. Returning customers generally cannot return opened bottles except when trying a new product for the first time, and any other opened bottle of the same product will not receive credit.

Does Quantum Nutrition Labs offer free shipping?

Yes, supplement orders over $99 ship free via ground within the contiguous USA, while orders below that threshold pay a $9.95 ground shipping fee. Hawaii and Alaska carry a flat $19.95 shipping rate instead.

What happens if a Quantum Nutrition Labs product arrives damaged?

Any damage must be reported within 10 days of receiving the package, and the outer shipping carton along with the damaged product needs to be kept, since the shipper will not process a damage report without them. Contacting the company immediately after noticing the damage is the fastest way to resolve it.

Does Quantum Nutrition Labs offer price protection if an item goes on sale later?

Yes, if the price on a product drops within 7 calendar days of a customer receiving it, that customer can request a refund or credit for the difference by contacting the company within that same 7 day window. This does not apply to limited-time price cuts tied to events like Black Friday or Cyber Monday.

Can I use a promo code after my Quantum Nutrition Labs order is already placed?

No, coupon codes cannot be applied retroactively once an order has been submitted, and orders cannot be modified to add or remove items afterward either. Double checking the cart and applying any code before finalizing checkout is the only way to use it.

Saving Guide

Why the 45 day window is longer than it first appears

Since the return period runs a full 45 days from the invoice date rather than the delivery date, there is more breathing room than many supplement companies offer to decide whether a new product is actually working before the window closes.

Weighing the restocking fee against a return

Because even a successful return carries a 15% processing fee, it is often more cost effective to try a smaller bottle or sample size of an unfamiliar product first rather than buying a large supply and planning to return what doesn't work out.

Using the first time opened bottle allowance wisely

New customers get some flexibility to return one opened bottle per product type across up to two different products, so it makes sense to use that allowance on the items with the most uncertainty rather than something already familiar.

Clearing the free shipping line efficiently

Orders need to reach $99 for free ground shipping, so combining a few smaller supplements into one order rather than placing separate purchases is a straightforward way to avoid the $9.95 shipping charge on orders below that mark.

Watching for the 7 day price protection window

Since a price drop within 7 days of delivery can be refunded as a credit or adjustment, it is worth keeping an eye on a product's price shortly after an order arrives, particularly outside of major sales events where this protection does not apply.

Applying a promo code before finalizing checkout

Because codes cannot be added after an order is placed and orders cannot be modified afterward, it is worth double checking that a valid code from this page is actually applied and reflected in the total before completing the purchase.

What to check before checkout

Confirm the order totals $99 or more to avoid a shipping fee, apply any promo code before finalizing the purchase since it cannot be added later, and keep the original packaging in case a return within 45 days becomes necessary.
