The Best Supplements is sure you will be happy with your order. However, if for any reason you are not completely satisfied with one of our products, we gladly offer a 30-day money-back satisfaction guarantee to all Retail or Preferred Customers. If a customer is dissatisfied with any product for any reason, you may return the item in its original packaging, along with the original invoice. The customer is responsible for the cost of return freight. In order to facilitate the return process, the Retail or Preferred Customer is required to contact The Best Supplements Customer Service Department to obtain a Return Merchandise Authorization (RMA) Number. This number must be written on the outside of the shipping box. If a package is returned without an RMA Number, the refund may be delayed or refused.  Please also indicate the reason for return on your invoice or an attached note.

We are so confident our products will provide you with the benefits you are searching for because we only offer the finest products from some of the leading manufacturers, raw material suppliers and some of the most brilliant formulation minds in the health industry.  At The Best Supplements we don’t offer any fad products, gimmicks or hype, all the products on this site are from sustainable, quality companies with the best reputations. These may not be the cheapest products, we believe when it comes to what you put inside your body is the most important thing and this is not the time to cut corners. You may find the same brand for an unusually low price on other sites on the internet, but please be aware there are imposter, forged, copycat products out there where the packaging looks just like the original but the product inside the bottle is very low quality.  All products we purchase at The Best Supplements come directly from the manufacturer, never from 3 parties distributors in between.  Feel free to ask for a Certificate of Analysis on any of the items you purchase from us.
