750mg
Sodium
Built for meaningful electrolyte replacement during heavy sweat, long shifts, and heat exposure.
Operational Hydration
Hydration built for demanding conditions.
Developed for long days, heavy sweat, physical workload, and repeated use.
Built around real-world demand
The harder the environment pushes, the more intentional hydration needs to be.
Heat, heavy gear, long shifts, and sustained workload all change what hydration needs to do. Operational Hydration was developed around those demands, not around trends, oversized ingredient panels, or marketing noise.
Heat
Sweat sodium losses climb.
Replacement has to keep pace across repeated servings.
Heavy gear
Output stays high.
Fluid has to reach the bloodstream, not sit in the gut.
Long shifts
Use is repeated.
Tolerance is designed in from the start.
The formula
Designed so every ingredient has a purpose.
Focused. Functional. Built around what hydration actually needs to do.
Kpotassium
Potassium
Complements the core electrolyte system to support normal fluid and electrolyte balance during sustained work.
4g
Dextrose
Enough carbohydrate to support sodium-glucose transport and fluid uptake, without turning hydration into a high-carbohydrate drink.
Tolerance by design
What is left out matters as much as what is in.
Operational Hydration was developed with GI tolerance in mind from the start. The formula stays focused rather than loading in ingredients simply to make the label look more complete.
Left out
Magnesium
Certain supplemental forms and doses can contribute to GI discomfort during repeated use.
Left out
Bulk sweeteners
Small amounts of high-intensity sweet proteins provide sweetness instead.
Left out
Sucralose, dyes, blends
The formula is built to be transparent, not hidden.

Questions
What buyers ask.
Straight answers in REZCOR’s own words. Anything else, ask product support.
Why 750 mg of sodium?
For heat exposure, load carriage, sustained output, and protective equipment, sweat sodium losses routinely exceed what low-sodium drinks can replace. 750 mg is a functional decision calibrated for meaningful replacement across repeated servings.
Why only 4 g of dextrose?
Carbohydrate in operational hydration is an absorption facilitator, not an energy strategy. Four grams of dextrose supports sodium-glucose cotransport without adding unnecessary osmotic load, residue, or calories.
Why is there no magnesium?
Magnesium was intentionally left out of the core electrolyte system because certain supplemental forms and doses can contribute to GI discomfort during repeated use.
How is it sweetened?
Small amounts of high-intensity sweet proteins provide sweetness without relying on large amounts of bulk sweeteners. REZCOR is formulated without sucralose, without dyes, and without proprietary blends.
Can it be used shift after shift?
Operational Hydration was developed with GI tolerance in mind from the start. The formula stays focused rather than loading in ingredients simply to make the label look more complete.
