Drug class: Vitamin and Mineral Supplement

Overview

Emergen-C is an over-the-counter dietary supplement that contains high doses of vitamin C, B vitamins, and electrolytes. It is commonly used to support immune health, boost energy, and replenish nutrients lost during physical activity or illness. The main ingredient, vitamin C (ascorbic acid), is an antioxidant that helps protect cells and supports the immune system. The B vitamins in Emergen-C play a role in energy production, while added electrolytes (such as potassium and sodium) help maintain hydration. Emergen-C is not a treatment or cure for colds or flu, but it may help reduce the duration or severity of symptoms in some people. It is important to use Emergen-C as directed and not exceed the recommended daily dose, as excessive intake of certain vitamins can cause side effects.
