“Tianji True Slim” Contains Hidden Drug Ingredient That Dangerously Increases Blood Pressure and Heart Rate

The FDA is advising consumers not to purchase or use “Tianji True Slim,” a product promoted and sold for weight loss, cleansing the digestive system, improving body metabolism, restoring energy, improving circulation, and eliminating water retention. This product is promoted on, and possibly sold in some retail stores.


An FDA laboratory analysis confirmed that “Tianji True Slim” contains sibutramine.  Sibutramine is a controlled substance that was removed from the market in October 2010 for safety reasons. The product poses a threat to consumers because sibutramine is known to substantially increase blood pressure and/or pulse rate in some patients and may present a significant risk for patients with a history of coronary artery disease, congestive heart failure, arrhythmias, or stroke. This product may also interact, in life-threatening ways, with other medications a consumer may be taking.


This is one example of a growing trend of products marketed as dietary supplements or conventional foods with hidden drugs and chemicals. These products are typically promoted for weight loss and body building, and are often represented as being “all natural.” Consumers may unknowingly take products laced with varying quantities of approved prescription drug ingredients, controlled substances, and untested and unstudied pharmaceutically active ingredients. The FDA is unable to test and identify all products on the market that contain potentially harmful hidden ingredients. Enforcement actions and consumer advisories for tainted products only cover a small fraction of the tainted over-the-counter products on the market.
