PREP
Arrive normally hydrated through routine drinking and meals. Aggressive pre-exercise hyperhydration is a specialized strategy with mixed context-dependent evidence and possible gastrointestinal trade-offs.

Performance Hydration
Hydration strategy should follow the athlete, the session and the environment, not a single universal drinking rule.
Start with contextDuration, intensity, temperature, humidity, clothing and access to fluid all change the problem.
Sweat loss variesSweat rate and sweat sodium concentration differ substantially between athletes and even between sessions.
Hydration is one inputFuel, cooling, pacing, sleep and training status also shape performance and recovery.
Performance first principles
Replace what matters without turning hydration into a rigid formula
Exercise increases metabolic heat production and can increase sweat losses, especially in hot conditions. Fluid availability matters because progressive body-water loss changes cardiovascular and thermoregulatory strain, but the performance effect is not identical in every sport or protocol.
Research also shows that simple thresholds can be misleading. The impact of exercise-induced dehydration depends on the environment, exercise design, starting hydration, opportunity to drink and the athlete's ability to self-pace.
A practical strategy therefore starts with the session: how long it lasts, how hard it is, how hot it is, what the athlete typically loses, and whether another session follows soon.
Build the plan
PREP → PERFORM → RECOVER
PERFORM
Use thirst, planned access, sweat patterns, duration and conditions to guide intake. Longer or hotter sessions can make carbohydrate-electrolyte beverages more relevant than water alone.
Perform →RECOVER
Restore fluid and sodium when meaningful sweat losses occurred, especially when recovery time is short. Rehydration is only one part of complete recovery nutrition.
Recover →Where Best Hydrate may fit
A prepared carbohydrate-electrolyte drink within a broader plan
Best Hydrate adds glucose and listed electrolyte sources to water. That can make it a practical option when an athlete wants a prepared hydration beverage rather than plain water alone.
It should not be presented as a universal performance enhancer. The evidence for carbohydrate-electrolyte drinks is strongest in contexts where exercise-associated fluid loss, longer duration, heat, limited food availability or rapid recovery make fluid, carbohydrate and electrolyte replacement more relevant.
Runners & high-sweat athletes
Electrolytes for runners should match the run, heat and sweat losses
For shorter runs in mild conditions, water and normal meals may cover much of the hydration need. As duration, heat or sweat losses rise, sodium-containing fluids can become more useful because athletes are replacing both water and electrolytes.
Some high-sweat athletes may need a higher-sodium plan than others. Best Hydrate can contribute fluid and sodium when prepared according to the current label, but it should not be treated as a universal sweat-replacement formula.
Choose the use case
Different sessions, different priorities
Endurance
Long-duration work brings fluid, carbohydrate and electrolyte planning together.
Endurance →Heat & High Sweat
Environmental heat and high sweat rates raise the cost of poor fluid access.
Heat & High Sweat →Recovery
Rehydration needs to fit beside refuelling, repair and rest.

LOW-SUGAR HYDRATION
LOW SUGAR HITS THE HYDRATION SWEET SPOT.
~1 g of sugar per 100 mL prepared. Best Hydrate keeps a small amount of purposeful glucose in the formula for sodium-glucose transport while avoiding a conventional high-sugar load.
Purposeful glucose. Not zero. Not overloaded.

More context
Performance hydration starts with the conditions
Training duration, intensity, heat, clothing, sweat rate, access to fluids and the rest of the diet all change the hydration problem. Best Hydrate is one option within that broader strategy, not a promise that one formula universally improves performance.
