• We have a 30-day money back guarantee, which means you have 30 days after receiving your item to request a return. 

• To be eligible for a return, your item must be in the same condition that you received it, unused, with the seal in tact, and in its original packaging.

Unwanted items- we offer a "no-quibble" 14-day guarantee for all items returned unused and in the original condition and packaging.

Damaged items- all damaged items reported within 5 days of receipt can be returned for a full refund or replacement.


• You will be responsible for any return delivery charges if the item is not damaged.

• Damaged items are returned free of charge. Details of such will be provided upon requesting a return.

• To place a return, you can contact us at support@knownnutrition.com

• Once accepted, we will provide instructions on how and where to send your package.

• Items sent back to us without first requesting a return will not be accepted. 

Please inspect your order upon receipt and contact us immediately if the item is defective, damaged or if you receive the wrong item, so that we can evaluate the issue and make it right.


• Unfortunately, perishable goods where the safety seal has been broken cannot be returned.

• The fastest way to ensure you get what you want is to follow the return process above. Once the return is accepted, make a separate purchase for the new item.


• We will notify you once we’ve received your return, and let you know if the refund was approved or not.

• If approved, you’ll be automatically refunded on your original payment method.

• Please remember it can take some time for your bank or credit card company to process and post the refund too although this is typically 3-5 working days.
