The Health Sciences Authority (HSA) has found that the "Ke Le" weight loss product sold online contains two undeclared potent medicinal ingredients that could pose serious health risks.
Ke Le has been promoted online as an appetite suppressant for weight loss.
The ingredients, ephedrine and pseudoephedrine, are typically used as medicines to relieve blocked nose and cough.
However, the recommended dosage instructions for the product would have caused unknowing consumers to take more than four times the limit of ephedrine for the treatment of common cold, flu and allergies.
HSA has warned that consuming such dangerously high levels of ephedrine can cause serious and life-threatening adverse effects.
