PERFORM • BEST HYDRATE
Perform at YOUR best.
Keep purposeful hydration within reach while you are active. Best Hydrate combines purposeful glucose with five highlighted electrolytes and just ~1 g sugar per 100 mL prepared.
01
When it fits
During training, sport, outdoor activity, demanding work, or other periods when convenient hydration matters.
02
How to use it
Keep the jar within reach. Add one scoop to 500 mL of water, mix lightly, and enjoy.
03
The simple cue
Mix lightly. Sip. Keep moving.

Duration mattersLonger sessions create more opportunity for fluid, sodium and carbohydrate deficits to accumulate.
Fuel and fluid interactA hydration drink can contribute carbohydrate, but endurance fueling often requires additional food or concentrated carbohydrate sources.
Practice the planRace-day intake should be tested in training for taste, gut comfort, access and pacing.
Long-duration exercise
Endurance is a logistics problem as much as a physiology problem
During prolonged exercise, the athlete has to manage several moving targets at once: body heat, sweat loss, thirst, carbohydrate use, gastrointestinal tolerance and access to aid stations or carried supplies.
That is why a strategy that works for a 40-minute session may be inadequate for a multi-hour event. As duration increases, carbohydrate-electrolyte drinks can become more useful, but they still need to fit into the athlete's complete fueling plan.
Individual losses
Use the event to estimate what you need to carry or access
Sweat losses can change with pace, body size, acclimatization, clothing and weather. A useful training exercise is to compare body mass before and after representative long sessions while recording fluid intake, then use the pattern to improve planning.
The target is not necessarily to replace every millilitre while moving. The practical objective is to avoid a deficit or excess that meaningfully compromises comfort, safety or performance.
Endurance plan
Four questions before race day
How much do you usually sweat?
Use representative training sessions, not a single test in a different climate.
Where does carbohydrate come from?
Drinks, gels and food may all contribute. Do not assume a hydration product alone covers endurance fueling needs.
What does your gut tolerate?
Concentration, volume, timing and total carbohydrate load can affect gastrointestinal comfort.
Best Hydrate in endurance
Useful as hydration, not a claim to replace the rest of the plan
Best Hydrate provides a prepared source of fluid, glucose and listed electrolytes when mixed according to the current label. In endurance settings, that can be one component of an athlete's intake strategy.
The product should not be framed as a complete endurance fuel. Longer events commonly require carbohydrate intake beyond what a lightly sweetened hydration formula is intended to provide, and sodium needs can vary widely between athletes.

Endurance nutrition is highly individual. Product use should remain consistent with the current label and the athlete's broader fueling plan.
Heat raises strainHigher environmental heat can increase cardiovascular and thermoregulatory demands during exercise.
Sweat losses varyRate and sodium concentration change with athlete, intensity, climate and acclimatization.
Cooling still mattersA drink cannot substitute for pacing, shade, airflow, rest or emergency heat-illness response.
Why heat changes the plan
Sweat cools the body, but it also moves water and electrolytes out
Evaporating sweat is one of the body's main cooling mechanisms during exercise. In hot environments, especially with high work rates, sweat losses can accumulate quickly and make access to fluid more important.
Recent evidence also shows that heat and dehydration can alter substrate use during prolonged endurance work. These physiological effects do not create one universal prescription, but they reinforce the value of planning before the session starts.
Heat and electrolyte losses
Hotter conditions can make fluid and sodium replacement more important
Sweat losses vary across athletes, sessions and environments. Plan fluid access, cooling and electrolyte intake around the duration and conditions rather than a single universal target.
Longer hot sessions can make sodium-containing drinks more relevant, while total fluid, food, health conditions and pacing still matter.
Heat strategy
Reduce the problem before trying to drink your way out of it
Acclimatize
Repeated heat exposure can improve thermoregulatory responses. Increase exposure progressively rather than jumping directly into full load.
Shift timing
When possible, move demanding sessions away from the hottest part of the day.
Plan access
Know where water and electrolyte drinks will be available before the session begins.
Watch symptoms
Confusion, collapse, severe weakness, loss of coordination or other concerning heat-illness signs require immediate action, not more training.
Best Hydrate in the heat
Electrolyte-containing fluid can be useful when sweating is prolonged
Best Hydrate provides water, glucose and listed electrolyte sources when prepared as directed. This can make it a practical beverage option during prolonged sweating.
Use an electrolyte-containing drink in the context of the session, conditions, sweat and your established routine. Longer, hotter and higher-sweat sessions increase the importance of planning fluid and electrolyte access.
High sweat day
Prepare the bottle before the heat starts
Use the current label dilution and carry enough safe fluid for the conditions and route.
