HYDRATE
THE BODY.Sharpen the Mind.

The first sport hydration formula built for both what dehydration does to your body and what it does to your brain. When you lose fluid, you don't just lose energy. You lose sharpness.

Your brain
suffers before
your body gives out.

Every coach knows dehydration hurts physical performance. What most do not know is that the cognitive effects hit first — and hit hard.

Reaction time slows. Decision-making breaks down. Concentration disappears. For an athlete reading a defense, tracking three players at once, or processing a play in real time — that is not a minor inconvenience. That is the difference between a great play and a costly mistake.

No sports drink on the market has addressed this. Until now.

body weight fluid loss triggers measurable cognitive decline — reaction time, focus, decision-making.

Before. During. After.

Acuity is the only sport hydration product with a scientifically timed three-phase protocol. Each phase is grounded in published sports science.

01
Before · Prime
Activate
30–60 minutes pre-activity

L-Theanine reaches peak cognitive effect in 30–60 minutes. Pre-loading sodium primes the absorption channel. Most athletes arrive dehydrated. Acuity Before changes that.

02
During · Sustain
Perform
Every 15–20 min during activity

For sessions over 60 minutes or in heat, Acuity replaces electrolytes as they are lost. Dual carbohydrate system fuels performance without GI stress. Don't wait until you're thirsty.

03
After · Restore
Recover
Within 30 minutes of finishing

For every pound of body weight lost, drink 16 oz. Sodium drives fluid retention. B12 and B6 support neurological recovery. Be ready before the next session begins.

Every ingredient
earns its place.

Dextrose + Sucrose 12g
Dual carbohydrate sources activate sodium-glucose co-transport using two gut pathways simultaneously. Faster absorption, less GI stress. The same mechanism hospitals have used since 1968.
Sodium Chloride 240 mg
Primary electrolyte lost in sweat. Drives fluid retention and activates the absorption mechanism. Calibrated to sweat science, not just flavor balance.
Potassium Citrate 110 mg
Cellular fluid balance and nerve signaling. Citrate form buffers pH naturally and is gentler on the stomach than potassium chloride.
Magnesium Citrate 25 mg
Central to muscle relaxation, energy production, and neuromuscular signaling. Involved in over 300 enzymatic reactions. Most athletes are mildly deficient.
L-Theanine (Suntheanine®) 125 mg
Increases alpha brain wave activity — the zone-like state athletes describe as peak focus. Calm, controlled alertness without stimulants. No competitor carries this.
Vitamin B6 (Pyridoxine HCl) 44% DV
Co-factor in dopamine, serotonin, and GABA production. Maintains the neurochemical baseline needed for sharp thinking under competitive pressure.
Vitamin B12 (Methylcobalamin) 208% DV
Active form — not cheap cyanocobalamin. Supports nerve conduction speed, mental clarity, and oxygen-carrying red blood cell production. Better absorbed in dissolved format.

SCIENCE
⚗️
Sodium-Glucose Co-Transport

When sodium and glucose are consumed together, they activate a specific absorption channel in the gut wall — pulling water into the bloodstream significantly faster than water alone. The same mechanism hospitals have used in IV fluids since 1968. That is the foundation of Acuity.

Faster absorption vs. water alone
🧠
Cognitive Performance Layer

L-Theanine increases alpha brain wave activity — the focused, zone-like mental state athletes perform best in. Combined with B6 for neurotransmitter support and methylcobalamin B12 for nerve conduction speed, Acuity addresses what no other hydration product does.

Calibrated for Athletes

Acuity is not a clinical ORS or a hospital IV. It is the hospital mechanism calibrated for healthy, high-performing athletes — enough sodium and glucose to activate rapid absorption, without the medicinal concentration. Designed for the field, the court, and the track.
