OPTIMUM NUTRITION® AMIN.O. Energy Hydration + Focus

You need energy to push through your workout. You need electrolytes to stay hydrated. You need amino acids to protect your muscles. Most athletes are mixing three different supplements just to get through one training day.

OPTIMUM NUTRITION® AMIN.O. Energy Hydration + Focus is an all-in-one workout supplement that delivers energy, hydration, and recovery in a single convenient stick pack.

One Supplement For All Your Needs

Natural Caffeine That Works – 100mg of caffeine from green tea and coffee bean gives you clean energy without the jitters or crash. It's the exact amount to dial in your focus for that key workout—not so much that you're bouncing off walls, not so little that you're still dragging.

5g Amino Acids to Support Muscle – Your body burns through amino acids during exercise, then breaks down your hard-earned muscle to get more. The 5g amino blend including BCAAs stops that breakdown in its tracks, keeping your muscles fueled and protected when you need it most.

440mg Electrolyte Blend That Matches Your Sweat – Sodium, potassium, and magnesium replace what you're losing through sweat. This isn't some token amount—it's a real electrolyte dose designed to keep your muscles firing and prevent that mid-workout bonk.

Research shows that combining amino acids with electrolytes enhances cellular hydration better than carb-electrolyte drinks alone. The amino acids actually help your body absorb and retain more water at the cellular level, meaning you stay hydrated longer. Plus, studies on endurance runners found that BCAA-electrolyte beverages reduced muscle damage markers and maintained lower limb strength better than standard sports drinks.

How to Use AMIN.O. Energy Hydration + Focus

Pre-workout fuel: Mix one stick pack with 16.9 fl oz of water 15-30 minutes before training. The caffeine kicks in fast, the aminos get to work immediately.

During long sessions: Take another pack at the 90-minute mark to keep energy and hydration levels steady.

Pro tip: Keep a few stick packs in your gym bag, car, or work desk. When you need to train but don't feel ready, grab one 20 minutes before and watch your body respond.

From CrossFit athletes to ultrarunners, endurance athletes trust Optimum Nutrition—the world's #1 sports nutrition brand—for banned substance testing and consistent quality. Every batch is tested, every ingredient is verified.

This isn't just another pre-workout. This is your complete workout solution in a single stick pack—energy, hydration, and recovery that fits in your pocket.
