In the News: Nature Made® TripleFlex® Triple Strength

Pharmavite LLC, the manufacturer of Nature Made®, disputes the Consumer Reports’ chondroitin sulfate testing methodology used for its Nature Made TripleFlex® Triple Strength product as featured in the publication’s October issue, which review of glucosamine and chondroitin combination products.  The recent challenge from Consumer Reports is about the amount of chondroitin sulfate in our products as compared to what is stated on the label; it is not about safety.  Nature Made TripleFlex Triple Strength products are safe and effective.


Pharmavite takes the Consumer Reports findings seriously and respects the publication’s role in evaluating products for consumers.  However, in this particular situation, we strongly dispute its testing methodology.  Why?  Consumer Reports didn’t use a test methodology for measuring the chondroitin sulfate in the products that was officially accepted.  To be validated a testing methodology; the method must be capable of providing reproducible results among multiple laboratories.  The level of reproducibility has not been achieved with the test method used by Consumer Reports.  Ironically although Consumer Reports recognizes USP as a credible standard setting organization and indeed used their test methodology for other tests on these products, it did not use UPS’s official and validated chondroitin sulfate testing mythology. 


In contrast, we test every batch of our TripleFlex products using the official, industry-recognized, USP-validated testing methodology.  Independent test results using this methodology found that the products noted in this article all met the standard set by Consumer Reports for its quality rating.  Had Consumer Reports used the USP testing methodology for our product, we would have been listed as a product that met all of the quality criteria.


We believe that the Consumer Reports different testing methodology is producing results that are not representative of the levels of chondroitin sulfate in the Nature Made TripleFlex product formulation.  Of note, Consumerlabs.com, an independent testing organization similar to Consumer Reports, published tests results of our TripleFlex products in May 2012, which indicated that our products met label claim.


You, our consumer is very important to us. Therefore, we will continue to investigate the difference in the test methodologies to try to understand why the Consumer Reports results are so different from our own.
