Energy bar - Definition and Overview

An energy bar is a dietary supplement often consumed by athletes or other physically active people to maintain their dietary needs in light of their strenuous physical activity.

As the name indicates, they are mainly a source of food energy, primarily complex carbohydrates. They also tend to contain a source of protein (often soy), plus a selection of vitamins and minerals. The flavours added to the ingredients often have them resemble baked goods, such as cookies or muffins, to make them more appealing.

The packaging of a typical bar will have a precise nutritional breakdown in order to assist the athlete in maintaining a dietary regimen. Major brand names in North America include PowerBar and Clif Bar.
