Dietary supplements, particularly weight loss and energy products containing herbals or complementary nutritionals, are a significant cause of emergency department visits for cardiovascular adverse events (palpitations, chest pain, tachycardia) in young adults aged 20-34.

If you are taking weight loss or energy supplements, be aware that they can cause heart palpitations, chest pain, or rapid heart rate, especially if you are between 20 and 34 years old. These products are not strictly regulated for safety before sale. If you experience these symptoms, seek medical attention and inform the provider about the supplement you are taking.
