ABOUT THIS PRODUCT
Enjoy Optimum Nutrition Amino Energy Sparkling RTD as an ice-cold energy kick during or after your exercise! This delicious drink is more than just a refreshment. Whether you are planning to run a marathon, join a bike trip, squeeze in an extra hard HIIT session, or simply enjoy an active weekend with your friends – Optimum Nutrition Amino Energy Sparkling RTD supports you through strenuous and exhausting days and supplies your body with important minerals and amino acids that have been lost. The harder you work out, the more you sweat – that much is clear. But did you know that extensive sweating makes you lose important electrolytes, which can lead to massive exhaustion and dehydration? Electrolytes are particles that carry a positive or negative electric charge in your body. These mineral are used in metabolic processes and required for several important bodily functions, including maintaining acid-base balance, proper nerve + muscle function, and keeping you hydrated. Optimum Nutrition Amino Energy Sparkling RTD contains added electrolytes and much-needed minerals like potassium, sodium and magnesium to get you hydrated, improve your endurance and boost your performance.
- Sparkling hydration drink.
- Supports muscle recovery after exercise.
- Improves energy & focus.
- Replaces electrolytes.
- Delicious & convenient.
Each can contains a blend of amino acids, including L-Leucine, L-Threonine, L-Theanine, L-Citrulline, Micronized Taurine, Sustamine L-Alanyl-L-Glutamine and L-Lysine Hydrochloride. Amino acids are the building blocks of protein and responsible for processes, including reducing fatigue, boosting cognitive function, speeding up muscle growth, increasing endurance, and supporting repair processes. To further increase your energy levels and focus during a tough sesh, 100mg of caffeine from natural sources has been added. It is widely known that a single dose of caffeine can boost physical and mental performance, improve focus and stimulate fat burning.
Optimum Nutrition Amino Energy Sparkling RTD is free from fat or sugar plus it contains only 5 calories and 1 g of carbohydrates per can, making it a very convenient low-calorie drink. Enjoy it before or after training or any time of the day as a convenient energy kick. Rehydrate your body with this sparkling powerhouse and give it what it needs to perform like never before!
