The explosive rise of weight-loss products marketed through social media has made consumer vigilance more urgent than ever, especially as online ads increasingly push supplements described as “natural,” “safe” and “fast-acting” without any scientific proof or regulatory approval to back those claims.
According to Mudhi Al-Hajri, a therapeutic and community nutrition expert, who spoke exclusively to Gulf Times, the recent warning issued by Qatar’s health authorities over a slimming product found to contain undeclared pharmaceutical substances is a stark reminder that many so-called natural products may conceal serious health risks.
Laboratory testing revealed the product contained sibutramine and phenolphthalein, two pharmaceutical compounds that were not disclosed on the label, effectively making it adulterated and potentially dangerous to consumers.
Sibutramine was once prescribed as an anti-obesity medication but was withdrawn from many international markets after studies linked it to higher risks of high blood pressure, rapid heart rate, heart attacks and strokes in vulnerable patients. Phenolphthalein, formerly used as a laxative, has also been discontinued in numerous countries over safety concerns and its possible association with an increased risk of certain cancers after prolonged use.
Al-Hajri warns that the greatest danger lies in the fact that these substances are deliberately omitted from ingredient labels. As a result, consumers may unknowingly ingest prescription-strength drugs, exposing themselves to dangerous drug interactions and potentially life-threatening complications, particularly people with cardiovascular disease, hypertension, diabetes and older adults.
She explains that some unscrupulous manufacturers intentionally add these pharmaceutical compounds to trigger rapid appetite suppression or dramatic weight loss. Consumers, believing the results come from herbal ingredients, are misled into trusting products whose apparent effectiveness is driven by concealed medications rather than natural formulations.
Al-Hajri urges consumers to exercise caution by following several essential precautions: avoid purchasing weight-loss products through anonymous social media accounts or unverified online advertisements; ensure that any product is officially registered and licensed by the relevant health authorities; be wary of marketing claims such as “100% natural,” “no side effects” or “guaranteed results within days”; and consult a physician or qualified nutrition specialist before using any weight-loss supplement.
While legislation imposing penalties on those who import, sell or promote adulterated or unlicensed products is an important safeguard, Al-Hajri stresses that legal action alone cannot fully protect public health.
An effective consumer protection system, she argues, must combine strong legislation, rigorous regulatory oversight, sustained public education and close cooperation between government authorities and digital platforms.
She advocates tougher penalties against anyone involved in importing, distributing or advertising products containing undeclared pharmaceutical ingredients, alongside the confiscation and destruction of offending products. Repeat offenders, she says, should face stricter sanctions, especially when violations lead to serious health consequences or fatalities.
Equally important, she says, is closer coordination with social media platforms to ensure the swift removal of illegal advertisements and accounts promoting unlicensed products once notified by the relevant authorities, thereby reducing public exposure to potentially harmful supplements.
Public education remains the cornerstone of prevention. Al-Hajri calls for wider circulation of the names and images of non-compliant products, greater awareness of the risks posed by hidden pharmaceutical ingredients and stronger encouragement for consumers to buy only from trusted, regulated sources rather than relying on misleading ads or celebrity endorsements that lack scientific credibility.
“Human health should never become a testing ground or a vehicle for quick profit,” she says. “Every product introduced to the market must be safe, licensed and subject to rigorous regulatory oversight.”
She concludes that safeguarding consumers is a shared responsibility involving regulators, legislators, digital platforms, the media, healthcare professionals and consumers themselves. Ultimately, awareness prevents harm before it occurs, effective oversight keeps dangerous products off the market and strong legislation ensures accountability for those who endanger public health.
