Buying Guide: What to Look for in a Sparkling Energy and Hydration Drink
Caffeine Source and Content
Not all caffeine is created equal. Some drinks use synthetic caffeine that hits fast but fades quickly, while others rely on natural sources for a smoother lift. The Optimum Nutrition Amino Energy Hydration Drink provides 100 milligrams of caffeine from natural sources, which is enough to sharpen focus without jitters. If you are sensitive to stimulants, this moderate dose works well for pre-workout or an afternoon boost.

Combined with zero sugar and only 5 calories, it is a lean option for those watching their intake. For a deeper dive into recovery formulas, read our thorne amino complex berry review.
