The rising popularity of Ozempic-style patches, which claim to facilitate weight loss without injections, is raising eyebrows among health experts. These patches, inspired by the prescription drug Ozempic, are being marketed online with promises of significant weight reduction. However, experts caution that these claims lack substantial evidence and may not deliver the results consumers expect.
Understanding Ozempic-Style Patches
Ozempic-style patches, also known as GLP-1 patches, are said to contain a blend of herbal extracts such as berberine, green tea (Camellia sinensis), Garcinia cambogia, and bitter orange (Citrus x aurantium L.). While some laboratory studies suggest that these extracts could suppress appetite and regulate fat metabolism, there is little evidence to support their efficacy in humans for weight loss.
A review of scientific literature indicates that the weight loss effects of these ingredients are minimal. For instance, one study found that taking up to 3 grams of berberine daily showed only a slight impact on weight and waist circumference. Similarly, another analysis revealed that doses of 2.4 grams of green tea extract or over 4 grams of Garcinia cambogia did not significantly alter participants’ weight over respective study periods of 13 weeks and 17 weeks.
Effectiveness and Safety Concerns
The primary concern with these patches lies in their ability to deliver active ingredients through the skin. The skin’s lipid composition allows for the absorption of fat-soluble compounds while blocking hydrophilic substances. Consequently, if the extracts in these patches are produced using water-based processes, they are unlikely to penetrate the skin effectively and may remain inactive.
Moreover, the limited amount of herbal extract contained in these patches poses another challenge. Typically, these patches hold less than 0.1 grams of active ingredients, far below the dosages shown to have any effect in clinical studies.
Safety is another critical issue. The Therapeutic Goods Administration (TGA) in Australia regulates medical products, including herbal extracts. For a product to be sold in Australia, it must be listed on the Australian Register of Therapeutic Goods. Currently, there are no Ozempic-style patches registered, meaning their quality and safety have not been evaluated. Instances of contamination with undeclared plant materials, heavy metals, and prescription drugs have been reported in unregistered herbal products, posing potential health risks.
In summary, while the concept of weight-loss patches may appeal to those seeking quick solutions, experts advise caution. The lack of proven effectiveness and safety raises significant concerns. Instead of investing in unverified products, individuals looking to manage their weight are encouraged to consult healthcare professionals. Doctors and pharmacists can recommend evidence-based treatments tailored to individual health goals.
