The Health Sciences Authority (HSA) has ordered the recall of CuraLin Advanced Glucose Support capsules after tests revealed that they contain undisclosed prescription-only ingredients, which could pose serious health risks if taken without medical supervision.
Imported from the United States by LYC Nutrihealth, CuraLin was marketed as a natural supplement made with traditional herbs to support blood sugar control. However, HSA testing found the presence of glibenclamide and metformin—both prescription-only drugs used to treat diabetes.
These substances can cause life-threatening side effects if misused. Inappropriate use may result in dangerously low blood sugar levels, leading to seizures, coma, or even death. Other potential side effects include nausea, diarrhoea, cholestatic jaundice (a condition where bile flow is blocked), and, in the case of metformin, lactic acidosis—an acid build-up in the bloodstream that can be fatal.
The affected batches of CuraLin have expiration dates in September 2026 and have since been pulled from sale. Listings on major e-commerce sites such as Shopee and Lazada have also been removed.
HSA has warned diabetic patients not to take CuraLin, especially if they are already on prescribed diabetes medication, as the combination could lead to an overdose due to the additive effects of the drugs.
Consumers are advised to stop using the product immediately and consult a doctor if they feel unwell. HSA also cautioned against purchasing other CuraLin variants, which may also be adulterated.
Retailers found selling products containing undeclared medicinal ingredients may face up to two years in jail and a fine of $10,000.
