Optimum Nutrition Amino Energy Sparkling Hydration Drink — Watermelon 12 Pack, Sugar-Free 100 mg Caffeine

This sparkling hydration drink blends a crisp watermelon flavor with an amino acid mix, electrolytes and caffeine sourced from tea leaf or coffee bean. Designed for people who want a low-calorie pick-me-up without sugar, the formula adds BCAAs and other amino acids for post-activity support while keeping the taste bright and bubbly. Each 12 fl oz can contains 5 calories, zero sugar and 100 mg of caffeine, plus sodium, potassium and magnesium to assist everyday hydration.

How does this drink give energy without excess sugar?

The product uses 100 mg of caffeine from natural sources (tea leaf and/or coffee bean) to boost alertness while relying on sucralose for sweetness instead of sugar. Because the drink is lightly carbonated and low-calorie, it delivers a refreshing sensory cue that many users equate with more vibrant energy.

• 100 mg caffeine per serving from tea leaf and/or coffee bean
• Zero sugar; sweetened with sucralose
• Only 5 calories per 12 fl oz can
• Light carbonation for a refreshing mouthfeel

What role do amino acids and BCAAs play in this beverage?

Each can supplies a 5-gram amino acid blend containing branched-chain amino acids plus supporting amino acids like L-theanine and L-citrulline. These ingredients are included to complement activity and recovery routines, providing nutrients commonly sought after training sessions or long days.

• 5 grams amino blend including L-leucine, L-threonine and L-lysine
• Micronized taurine and L-alanyl-L-glutamine for stability and mixability
• L-theanine to support a smoother caffeine experience
• Formulation suitable for on-the-go use and between workouts

Will this drink help me stay hydrated during workouts or travel?

The beverage includes key electrolytes—sodium citrate, potassium chloride and magnesium phosphate—to help replace minerals lost through sweat and routine activity. While not a medical rehydration solution, its electrolyte content plus the fluid volume make it a practical choice for light to moderate exertion, commuting or long days.

• Sodium and potassium help maintain fluid balance
• Magnesium phosphate contributes electrolytic support
• Carbonated water provides a refreshing alternative to still drinks
• Convenient 12-pack format for travel, gym bags, or office stock

How does flavor and ingredient transparency affect my choice?

Watermelon flavor is achieved through natural and artificial flavoring with citric and malic acids for brightness and tartness. The label lists preservatives (potassium sorbate, potassium benzoate) and a clear amino blend so you can see what you’re consuming and decide based on taste preferences and ingredient needs.

• Natural and artificial flavoring for consistent watermelon taste
• Citric and malic acids for balanced acidity
• Transparent amino ingredient listing on the label
• Packaged to preserve carbonation and flavor in a 12 fl oz can

Who this is for: Optimum Nutrition Amino Energy Sparkling Hydration Drink is aimed at active adults, gym-goers and busy professionals who want a light, flavored beverage that supplies caffeine, electrolytes and amino acids without sugar or heavy calories. It’s well suited for anyone seeking an on-the-go, refreshing alternative to traditional energy drinks—perfect for pre-workout focus, between-set refreshment, travel or a midday lift when you want flavor, fizz and functional ingredients.
