Prevagen Authorized Dealer and Warranty Statement

Prevagen is firmly committed to providing our customers with safe and reliable products through authorized dealers. Unfortunately, Prevagen products are sometimes sold by companies that are not authorized to do so. Goods sold by these unauthorized companies are not purchased from Prevagen; instead they are acquired from a host of other sources. Due to the nature of the goods sold by unauthorized dealers and their business practices, products sold by unauthorized dealers are not entitled to Prevagen warranty coverage. We are using our best efforts (including this warning) to prohibit these companies from taking advantage of consumers, but these practices still exist. We urge you to use diligence when selecting a dealer to make your purchase.

Our policy is to honor product warranties only on products purchased from an authorized Prevagen dealer and only accompanied by a receipt or proof of purchase. If you purchase a Prevagen product from an unauthorized dealer or if the original serial number has been removed, defaced or altered, your Prevagen warranty will not be valid.

 

Online Sellers

A further note about online sellers (particularly those on Amazon.com or Ebay.com): Many resellers who sell through Amazon.com and Ebay.com are not authorized resellers of Prevagen products. When purchasing Prevagen products on Amazon.com or Ebay.com, it is important to note where the product is being “shipped from and sold by,” which is stated clearly in the header for each product.

Prevagen products sold by unauthorized dealers sometimes are purchased on a secondary “gray” market or may be damaged, defective or so-called “B” stock goods, or stolen goods.

 

Beware of Unauthorized Prevagen Products

Like many premium goods, Prevagen products are being stolen and sold, usually at drastically reduced prices and diminished quality. These products do not meet Prevagen standards and are not covered under Prevagen warranty. If you would like to report a suspected counterfeit Prevagen product or have questions concerning this issue, please contact Customer Service at 1-888-758-7358. We appreciate your help in maintaining the integrity of the Prevagen brand.

 

Beware of Other Product Package Alterations

Many times, products from unauthorized reseller have product lot numbers that have been changed or even removed all together. Some products are marked with arbitrary “Use By” or Expiration Dates. Any Prevagen product that does not have a product lot number issued by Prevagen should be returned. Removal or alteration of the original Prevagen product lot will automatically void the warranty on that product.

Some unauthorized resellers remove product inserts and informational materials designed to inform and assist you with the proper use of your purchase. If your Prevagen product is missing its outer box packaging, package insert, or has an obviously altered product lot number label, immediately contact whoever you purchased that product from for resolution and copy Prevagen.
