The Natural Energy BarTo perform at your best, the last thing you want to put in your body is a synthetic product. That's why we believe in using healthy ingredients, such as organic rolled oats, organic roasted soybeans, organic milled flaxseed and organic soy flour. With a mix of carbohydrates, protein, and fiber, CLIF BAR is a moderate glycemic index food. What does this mean? Basically, you'll benefit from a steady increase in blood sugar levels followed by a gradual decline (sustained energy!).Eat a CLIF BAR 1 - 2 hours before a workout or race, and you'll avoid the sugar high and crash associated with refined ingredients and sweeteners. A CLIF BAR delivers the boost you need without unwanted crash and burn. You don't have to be an athlete to enjoy a CLIF BAR, but with the extra energy a CLIF BAR provides you may find it hard not to be.
