The most common cause of Cushing syndrome (CS) is exposure to exogenous glucocorticoids. There is an increasing incidence of adulterated over-the-counter (OTC) supplements containing steroids. We present a case of Artri King (AK)-induced CS in a 40-year-old woman who presented with an intertrochanteric fracture of her right femur. Laboratory testing revealed suppressed cortisol and adrenocorticotropic hormone, which was consistent with suppression of the hypothalamic-pituitary-adrenal (HPA) axis. Following the cessation of the AK supplement, the patient’s HPA axis recovered, and the clinical manifestations of CS improved. This case emphasizes the need for better regulation of OTC supplements and the need for cautious use.
