Your Body Is Not
Like Anyone Else's
We didn't guess what your body needs. We studied thousands of athletes across dozens of sports, multiple climates, and every body type — and built a system that knows exactly how to hydrate you.
Thousands of Athletes. Real Sweat. Real Conditions.
We collected sweat data from athletes across the country — not in sterile labs, but in the real environments where they actually train and compete. Hot and humid summers in the Southeast. Dry desert heat in the Southwest. Cold and wet conditions in the Pacific Northwest. High altitude training in Colorado.
Each participant wore precision biosensors that measured sweat rate, electrolyte concentration, core body temperature, and hydration status in real time — during actual workouts, not simulated ones.

Every Sport Demands Something Different
A marathon runner and a powerlifter both sweat — but they lose entirely different ratios of sodium, potassium, and magnesium. We studied them all.
Distance Running
High sweat volume, significant sodium loss over time
Cycling & Spin Classes
Sustained output; potassium and magnesium depletion
Weightlifting & Strength
Lower volume but high mineral concentration in sweat
HIIT & Circuit Training
Intense bursts elevate sodium loss rapidly
Swimming
Sweat masked by water; dehydration often undetected
Hiking & Trail Running
Altitude and terrain increase fluid and mineral demands
Hyrox & Functional Fitness
Mixed-modal stress creates complex electrolyte profiles
Court Sports (Tennis, Basketball)
Stop-start intensity creates variable sweat patterns
Team Sports (Soccer, Lacrosse)
Duration and position affect hydration needs significantly
Yoga & Pilates (Hot)
Heat-driven sweat with minimal cardiovascular compensation
Boxing & Martial Arts
Rapid dehydration in short timeframes
Winter & Cold Weather Sports
Cold air masks thirst; dehydration risk is underestimated
Two People. Same Workout. Completely Different Needs.
Even when we put two athletes through the identical training session in the same conditions, their sweat profiles were rarely the same. Here's why.
Body Composition
Muscle mass, body fat percentage, and overall size directly influence how much you sweat and what's in it. Larger athletes with more muscle produce more heat and require proportionally more electrolytes.
Height & Weight
Surface area relative to body mass determines heat dissipation rate. Taller, leaner athletes shed heat faster. Heavier athletes retain it longer — both affecting fluid and mineral loss.
Climate & Humidity
In humid conditions, sweat evaporates slowly and the body compensates by producing more. In dry heat, evaporation is fast but electrolyte concentration in sweat is higher. Altitude further complicates the equation.
Training Age & Fitness Level
Highly trained athletes sweat earlier and in greater volumes — an adaptation that improves cooling efficiency. But this also means they deplete electrolytes faster than beginners at equivalent intensities.
Biological Sex
Hormonal differences influence thermoregulation. On average, female athletes begin sweating at higher core temperatures and lose different concentrations of key electrolytes than male athletes.
Activity Type & Duration
Short explosive efforts shift mineral loss toward magnesium and potassium. Long endurance efforts deplete sodium most significantly. Mixed-modal training creates unique compound profiles.
Acclimatization
Athletes who train in the heat regularly develop more efficient sweat glands that produce higher-volume, more dilute sweat. Unacclimatized athletes show more concentrated but lower-volume sweat.
Diet & Baseline Nutrition
What you eat affects what's available in your sweat. Low-sodium diets reduce sodium in sweat. High-potassium diets show elevated potassium excretion. Baseline nutrition shapes your hydration baseline.
Age
As we age, the body's thirst mechanism becomes less sensitive, sweat gland efficiency declines, and the kidneys become less effective at retaining key minerals — increasing the need for targeted supplementation.
We Studied the Science.
Now We Know Your Body.
After years of research and tens of thousands of data points, we've built predictive models that tell us — with high confidence — exactly how your body will respond to exercise, and what it will need to perform at its best.
When you tell us about yourself — your body, your sport, your environment — we're not guessing. We're matching you against a database of real athletes who share your profile. Your formula is built from their data, refined by our research, and made exactly for you.
You Tell Us About Yourself
Height, weight, body type, activity, climate. Basic inputs that our models use to build your initial profile.
We Match You to the Data
Our system cross-references your profile against thousands of athlete data points to predict your precise electrolyte needs.
