30-Day Money Back Guarantee


We are so confident that our products work that we're backing them with a 30-Day Money-Back Guarantee.

We ask that you try Nutralin® for a full 30 days (because diabetes is a process to work through with your veterinarian) before deciding if you want a refund. We suggest 30 to 60 days for both Sterling Coat®-Treaties and Vitali-Treaties® because they normally take longer to work.


Why? It's simple really. Our food-based products take a while to build up in your pet's system. This means it can take up to a few weeks before you notice the effects.


Remember, these are not prescription drugs.


Also, they must be kept resealed after each use. 


If you give them time to work, you will be pleasantly surprised.


So give our products a full 30 to 60 days of use before deciding what you think of them.

If you love them, great! But if after trying them for 30 to 60 days you're not satisfied, send them back for a full refund.

Our promise:

  • We accept returns on all items within 30 days from date of delivery
  • We will refund the entire purchase price of the order
  • There are no hidden fees or re-stocking fees

Please note: we can only issue refunds for the items returned to us so please send back all empty, opened and sealed items.

Should you wish to return any items, you must contact our office for a return authorization (RA) number along with return instructions, which will allow us to ensure there will be no delay in issuing your refund. Please note that without an (RA) return authorization, we can’t refund your purchase.

Please understand that it will take some time to process your return. Your credit should be finalized 5-10 days after we receive your return in the warehouse.

To get a return authorization number, please contact us within 30 days of the shipment date. You can email or call us with your questions, comments or concerns at any time. We welcome and appreciate your feedback. We hope that you enjoy shopping at: www.vinteknutrition.com and feel confident about your purchases.

You can obtain a return number by calling a customer service agent at 1-(605) 332-VINTEK (8468) or Toll Free (855) 332-VINTEK (8468) or email support@vinteknutrition.com
