There are times when your body has high energy demands. With a mix of carbohydrates, protein and fibre, CLIF Bars supply working bodies with the extra energy and nutrients they need for extended periods of activity. Wholesome and nutrient-dense, CLIF Bars are formulated to steadily increase blood sugar levels without creating a precipitous “sugar crash.” CLIF Bars help people who respect their bodies and the planet to push farther with sustained energy when normal intakes are not enough. What is CLIF Bar? CLIF Bar is the original energy bar in the United States that delivers an optimal blend of nutrition for sustained energy for times when your normal intake of energy and nutrients may not be enough. When should you eat CLIF Bars? For best results, CLIF Bars should be eaten about one to three hours before activity along with water to prevent hunger and supply energy to working muscles. During prolonged, lower intensity activity such as hiking or bike touring, CLIF Bars can be eaten during the activity to help satiate hunger and meet carbohydrate demands. CLIF Bars can also be eaten after exercise, as a snack between meals or during a long, busy day to help supplement energy and nutrients as required.
