Researchers from NSF International and Harvard Medical School set out to determine the presence and amount of experimental stimulants in dietary supplements labeled as containing deterenol and sold in the United States. They tested 17 brands of weight loss and sports supplements that contained the ingredient. Their result: Weight loss and sports supplements that listed Deterenol as an ingredient contained 9 banned stimulants and 8 different stimulant mixtures with up to 4 experimental stimulants per product.

“We urge doctors to be aware of the possibility that patients may inadvertently be exposed to experimental stimulants while consuming weight loss and sports supplements,” said Dr. Pieter Cohen, Associate Professor of Medicine Harvard Medical School, Internist with the Cambridge Health Alliance and co-author of the study, in a press release from NSF. “We’re talking about active pharmaceutical stimulants that have not been approved by the US FDA for oral use as prescription drugs or dietary supplements. These ingredients have no place in dietary supplements. “

John Travis, Senior Researcher at NSF International and co-author of the study, added, “These hidden stimulant cocktails have never been tested in humans and their safety is unknown. You never want to find unlabeled ingredients in supplements, but it’s especially important to find those strange browbones of experimental stimulants in products that are readily available in The United States.

The Responsible Diet Council has questioned aspects of the analysis. “This report continues to tell an unfortunate, but not surprising, truth about the Internet: When researchers like Dr. Pieter Cohen specifically looking online for products that contain an illegal ingredient, they are likely to find not only those illegal ingredients, but other illegal ingredients as well, ”said Steve Mister, CRN President & CEO The products identified in the analysis are not legal supplements, but are illegal products that disguise themselves as supplements in the hope of avoiding detection .

Mr. emphasized the difference: “Legitimate dietary supplements in the sports nutrition and weight management categories – those that most consumers would encounter in local stores or on popular shopping platforms – are safe, beneficial, and help consumers achieve their fitness and weight goals. As with other dietary supplements, these products are designed to complement smart lifestyle choices, e.g. B. Eat a healthy diet, exercise regularly and get enough sleep. “

As Mister pointed out, reputable natural products serve as gatekeepers to protect customers: “This report reminds consumers that where you buy nutritional supplements matters. The illegal products identified in the report come from unscrupulous online sellers who are unlikely to be found on the shelves of reputable retailers or popular online platforms. CRN reminds consumers to seek products from nationally recognized brands or private label products from trusted retailers. Avoid products that promise extreme results, research companies and supporting science, and always speak to a doctor for advice on how to use supplements responsibly.

One key point of the analysis that CRN agrees with is that stronger and more proactive enforcement actions are needed to protect the public from adulterated products on the market. “If the agency is made aware of illegal products, the FDA must act faster and more decisively to both create a deterrent and protect consumers,” said Misted. “The FDA lacks a system to efficiently track products that come onto the market. Therefore, CRN continues to advocate a mandatory product list as a solution. This would allow the FDA to identify new products and act more quickly to remove illegal products from the market. “

CRN offers tools that can help in the meantime. “Regulators and consumers should visit CRNs Supplement OWL (Online Wellness Library) for easy access to important product and manufacturer information. This self-regulatory initiative serves as the model for the mandatory product listing and shows brands that choose to be responsible for their labels and ingredients. Consumers can also visit CRN’s website Tips and resources on buying nutritional supplements. “

For its part, NSF noted that research indicates the need for independent testing and certification of dietary supplements. To earn NSF certification, products are tested for product formulation, label information, and harmful levels of specific contaminants and potentially harmful ingredients, as per the NSF press release. This further explains that NSF certified dietary supplements must be made in a manufacturing facility that is inspected twice a year to meet US FDA’s GMP (Good Manufacturing Practice) requirements. You will get NSF certification. Products are tested for product formulation, label information, and harmful levels of specific contaminants and potentially harmful ingredients. Products certified under NSF’s Certified for Sport program must meet additional requirements and are screened for 280 prohibited sports substances.
