When describing the 5-Hour Energy feeling, some people say it’s “like the sun coming up in my head.” That’s because when you’re feeling groggy and lethargic, 5-Hour Energy wakes up your brain and gets you back to feeling the way you want to feel – bright, alert, focused and energetic. What you won’t feel is jittery, or – crash. That’s because, unlike other energy drinks, 5-Hour Energy doesn’t jack you up with sugar, caffeine and herbal stimulants. Instead, it’s packed with stuff that’s good for you – B-vitamins, amino acids and enzymes.
