Nutramax Laboratories issued a statement in August 2018 urging consumers to return counterfeit pet dietary supplements sold by unauthorized resellers on Amazon:
“Nutramax Laboratories Veterinary Sciences, Inc. has determined that counterfeit versions of three leading veterinary Nutramax products – Cosequin® DS+MSM 132 and 250 counts chewable tablet bottle, Dasuquin® with MSM 150 count chewable tablet bottle for small to medium and for large dogs, and Proviable® DC 80 count capsules carton – have been sold by unauthorized third-party resellers on Amazon.
Most counterfeit and pirated products will probably be shipped directly from a third-party seller BUT not all third party sellers are bad.
However, even “ships from and sold by Amazon.com” products are not immune to counterfeits, as these items to are often commingled into the general FBA (fulfilled by Amazon) stock:
All those products often get pooled together by bar code, regardless of whether they come from the brands themselves or other distributors.
That means even if you buy something that is technically sold by Amazon under the brand’s name, you might end up with a product supplied by a third-party merchant, which may or may not be the real thing.”
Since the alert that went out in 2018 from Nutramax, it appears that many of the counterfeit sellers have been removed from Amazon but that doesn’t mean counterfeit products are not still there.
