Most energy drinks are loaded with large amounts of caffeine, sugar, and other substances that deliver a quick boost of energy. Sugar and fructose, both found in energy drinks, spike your insulin level briefly, which means an infusion of energy; but this surge is short lived. When the sugar is used up, your insulin level will plummet, resulting in a “crash” and fatigue.Energy drinks typically contain three to five times the caffeine in a same-size can of soda. Too much caffeine, and caffeine-like substances such as guarana, can cause side-effects such as irritability, insomnia, and rapid heartbeat. Sunrise® is different. It’s all-natural, free of added stimulants, artificial sweeteners, colors, or preservatives—there’s no harmful side effects with Sunrise®, so there’s no jitters or a “crash.”
