Body water lost
Measurable drop in strength, reaction time, and decision-making. In a sport of milliseconds, this is the fight.
Why hydration is performance.
A 2% loss in body water is enough to measurably reduce strength, reaction time, and decision-making — the three currencies of combat sports.
Chapter 01 · The Problem
Most electrolytes weren't made for fighters.
They're calibrated around runners, cyclists, or the average adult on a Tuesday. Combat athletes sweat harder, train more often, cut weight, and recover on a clock. Their physiology is a different problem.
Heavy sweat loss
1.5–2.5 L per hard session, mineral-rich.
Multiple sessions daily
Two-a-days leave no runway for slow recovery.
Weight cutting
Fluids and food restricted while output stays maximal.
Rapid recovery window
The clock resets tomorrow morning — every time.
Chapter 02 · The Loss
Sweat is not water.
Every litre a fighter loses in training carries a specific mineral fingerprint. Replacing water alone can leave the body flatter than before the session.
Ranges reflect published sweat composition data for trained athletes. Individual losses scale with heat, intensity, and genetics.

Chapter 03 · The Cost
The cost of dehydration.
Even small fluid losses change how a fighter performs, recovers and shows up the next day. Here is what the research shows.

Plasma volume falls
The heart works harder to move less blood. Perceived exertion rises before thirst even registers.

Mineral status the night before shapes muscle relaxation, sleep depth, and tomorrow's session.
Chapter 04 · The Answer
So we built the formula that meets the sport.
Not a general electrolyte drink with a fighter on the label. A profile engineered from published sweat data for trained combat athletes — dosed for the demands, not the average adult.
Chapter 05 · The Formula
Five inputs. Each tied to a physiological loss.
Nothing decorative. No filler carbs, no synthetic dyes, no caffeine hidden in the mix. Just the minerals and cofactors the sport takes back.
Na
Restores plasma volume lost in heavy sweatPink Himalayan Salt
Sodium is the dominant electrolyte in sweat — and the one generic drinks under-dose most. Hydō delivers a fighter-grade replacement, not a wellness sprinkle.
Mg
Muscle relaxation · sleep · recoveryMagnesium Bisglycinate
Chelated for absorption without gut distress. Backs muscular recovery between sessions and supports the deep sleep fighters live and die on.
K
Cellular fluid balance · cramp preventionPotassium Citrate
The counterpart to sodium. Keeps fluid inside working cells, not pooling between them. Under-dosed in almost every mainstream product.
TC
Antioxidant support · session-to-session recoveryTart Cherry
Polyphenols shown to blunt markers of exercise-induced muscle damage. The bridge that keeps back-to-back training days from compounding.
B6
Energy metabolism · nervous system supportVitamin B6 (P5P)
The active pyridoxal-5-phosphate form supports how the body converts fuel into usable energy and helps maintain nerve function under high training stress.
Benefits
Built into every scoop.
Hydration
Replenishes the electrolytes lost across long sessions.
Performance
Maintains plasma volume so output doesn't fall off late in rounds.
Recovery
Supports muscle function and sleep quality between sessions.
Muscle Support
Essential electrolytes to reduce cramps and sustain power through every round.
The Magnesium Decision
Not all magnesium is equal.
Magnesium powers sleep, muscle relaxation, and energy metabolism. But the form matters as much as the dose. We chose bisglycinate because fighters can't afford the side effects of cheap alternatives.
—
Magnesium Oxide
Poorly absorbed — often causes cramping and digestive distress.
—
Magnesium Citrate
Better absorbed, but still has a laxative effect at higher doses.
✓
Magnesium Bisglycinate
Chelated to glycine. Highly absorbable and gentle on the gut.
100mg per serve
Magnesium Bisglycinate
Chelated to glycine for high absorption without the laxative effect common in cheaper forms.
Deeper sleep
Supports the slow-wave sleep fighters need to recover between sessions.
Muscle relaxation
Helps reduce cramps and keeps muscles pliable through hard training blocks.
Less fatigue
Cofactor in ATP production — the energy currency burned in every round.
Gentle on the gut
No laxative effect. Easy to digest even when calories are restricted.
Most electrolytes stop at hydration.

FAQ
Questions, answered.
Hydō is built specifically around the electrolytes fighters lose in hard training — sodium, magnesium, potassium — without the sugar, synthetic dyes or flavour overload found in typical sports drinks.
