Verification for authentic extract without adulteration
In response to the growing problem of adulteration of grape seed extract, EuroPharma®, Inc., maker of the Terry Naturally® brand of dietary supplements, has created a verification program to authenticate its scientifically-studied French Grape Seed VX1.
While grape seed extract’s health promoting power has been investigated in over 1000 published studies, archived on the National Institutes of Health (NIH) electronic database, PubMed.gov, reports of adulteration have been reported, including the use of red peanut skins instead of legitimate grape seed extract, without revealing the presence of this top 8 allergen.
In a 2015 article in the journal Food Chemistry, researchers reported that 21 grape seed extracts were analyzed. They found that 15 of the 21 products had quality challenges, and 6 samples were adulterated with high levels of peanut skin. [Villani T, Reichert W, Ferruzzi M, et al.

“French Grape Seed VX1 is one of the most powerful supplements in the world, and studies have shown the potential for enormous health benefits. In fact, our French Grape Seed VX1, featured in all our Clinical OPC products, has been used in three very successful, published studies at Baylor University, and more are in the works. However, in the presence of widespread adulteration, we sought a way to reassure our customers that all necessary quality checks are happening behind the scenes to assure the authenticity of these products,” states Terry Lemerond, president and founder of EuroPharma, Inc.
“I am pleased to learn that EuroPharma has taken the additional quality control step to help ensure the proper identity and authenticity of its Grape Seed Extract (GSE). As we have confirmed in our peer-reviewed Grape Seed Extract Botanical Adulterants Bulletin, produced under the auspices of the ABC-AHP-NCNPR Botanical Adulterants Prevention Program, some lots of GSE have been confirmed to be adulterated with extracts derived from peanut skins. Both extracts contain some similar compounds which are not easily differentiated in the quality control laboratory unless appropriate analytical testing methodologies are employed,” states Mark Blumenthal, Founder and Executive Director of the American Botanical Council, a non-profit organization designed to provide education using science-based and traditional information to promote responsible use of herbal medicine—serving the public, researchers, educators, healthcare professionals, industry and media.
“Accordingly, even if a company has a competent in-house quality control laboratory, confirmation of GSE identity via a qualified third-party laboratory using a scientifically valid analytical method is frequently necessary to authenticate GSE and ensure that there is no adulteration with lower-cost materials,” states Blumenthal.
“We take several quality steps to assure French Grape Seed Extract VX1’s authenticity. Finished products are tested using High Performance Liquid Chromatography (HPLC). To detect the presences of an adulterant, we compare the raw material to a certified standard. This is done using High Performance Thin Layer Chromatography (HPTLC), which will tell if the raw material has been adulterated based on the separation patterns. All testing is performed at ISO 17025 certified laboratories,” states Nate Paske, Quality Assurance/Quality Control Specialist at EuroPharma, Inc.
A report by the Botanical Adulterants Bulletin on the Adulteration of Grape Seed Extract, spearheaded by the ABC, offers guidance on the current market and consequences for the consumer and the industry with regards to this problem. More information on this program can be found at HerbalGram.org.
