Build My Hydration ProfileWhether you're training, coaching, parenting, or just getting started with sports hydration — Acuity meets you where you are.
Every coach knows dehydration hurts physical performance. What most do not know is that performance effects show up early — and hit hard.
Hydration affects energy, focus, and execution during training and competition.
Most sports drinks focus on sweat loss. Acuity takes a broader approach to hydration and performance.
Acuity uses a three-phase hydration protocol for before, during, and after activity.
Designed for pre-activity hydration and performance support. Pre-loading sodium primes the absorption channel. Many athletes begin training already underhydrated.
For longer, harder, or hot-weather sessions, drink regularly based on your sweat losses, conditions, session duration and opportunities to drink.

Rehydrate based on fluid losses, thirst, conditions and the time available before your next training session or competition. When rapid recovery is needed, athletes may need to replace more fluid than the body weight lost during exercise.
Acuity combines carbohydrates and electrolytes because hydration depends on more than drinking water alone. The formula is designed around established hydration science to support fluid absorption and electrolyte replacement during demanding training.
Acuity contains 200 mg of Suntheanine® L-theanine and zero caffeine. We intentionally designed the formula without a stimulant so athletes can choose caffeine separately based on their age, tolerance, timing, and individual needs.
Every ingredient was selected with sprinting, explosive training, and high-intensity competition in mind.
Sodium and glucose work together through established intestinal transport pathways that support fluid absorption.
Acuity contains 200 mg of Suntheanine® L-theanine and zero caffeine. B6 supports normal energy metabolism and methylcobalamin B12 supports normal red blood cell formation — in a formula built without stimulants, artificial sweeteners, or unnecessary additives.
Acuity uses sodium and glucose to support fluid absorption, with a formula built for healthy athletes during training and competition.
