The science

Hydration is a system.

Hydration depends on more than water alone. Electrolytes help maintain fluid balance, support nerve signaling and normal muscle function. Here is how VYTL was built, and why every amount was chosen.

The fundamentals

What electrolytes actually do

Electrolytes are minerals that carry an electric charge. They help regulate fluid balance, support nerve signaling and enable normal muscle function. When you sweat, you lose both water and electrolytes. Replacing water alone does not replace the minerals lost with it.

Sodium
Helps maintain fluid balance and supports water absorption.
Potassium
Works alongside sodium to support fluid balance, nerve signaling and normal muscle function.
Magnesium
Involved in hundreds of enzymatic processes, including normal muscle and nervous system function.
Chloride
Works alongside sodium to help maintain normal fluid balance.
The system

Calibrated to work together

Electrolytes don’t work in isolation. Each amount in VYTL is set so that sodium, potassium, chloride and magnesium work together across fluid balance, nerve signaling and muscle function. Sodium and potassium sit in a 2:1 ratio, 380 mg to 190 mg, with chloride and magnesium in support.

The VYTL formula, per stick

Every amount deliberate. Nothing arbitrary.

The ratio

Why 2:1 sodium to potassium

Sodium and potassium play complementary roles in fluid balance, nerve signaling and muscle function. Sodium is the mineral lost fastest in sweat, so it leads. Potassium works with it inside the cell. VYTL pairs 380 mg of sodium with 190 mg of potassium, a 2:1 ratio.

The goal isn’t to maximize one mineral. It’s to hold both in a balance the body can actually use, day after day.

380 mg Sodium
2 : 1
190 mg Potassium
Set on purpose. Held every batch.
Bioavailability

Form influences absorption

The number on the label is only part of the story. The same mineral can be delivered in different chemical forms, and how much of it the body takes up varies between them. VYTL uses citrate forms across its potassium, magnesium and zinc, and pairs sodium citrate with sodium chloride, chosen for how well they dissolve, how well they are absorbed, and how they sit together in one clear glass.

MagnesiumMagnesium citrateTends to be better absorbed than magnesium oxide, the cheaper form most powders use.
SodiumSodium citrate + sodium chlorideTwo sources that together deliver 380 mg of sodium, with citrate softening the salt edge.
PotassiumPotassium citrateThe same citrate family as the magnesium, so the stick dissolves clear and tastes clean.
ZincZinc citrateA well-absorbed zinc source at a dose made for daily use.

Amount, ratio and form: each decided separately, each on purpose.

Beyond electrolytes

What else earns a place

Beyond the core electrolytes, two nutrients are included at measured doses, each for a specific reason and neither at a level that turns a hydration stick into a multivitamin.

Vitamin C40 mg
Supports normal immune function and contributes to the protection of cells from oxidative stress.
Zinc5 mg
Supports normal immune function. A measured amount for daily use, not a megadose.
Restraint

Measured, not maximal

More is not always better. Every dose in VYTL is measured for daily, repeatable use: enough to serve a purpose, without adding excess to make the label look stronger. High-sodium formulas exist for people losing liters of sweat in a race. Most days aren’t that. VYTL is built for the days that are.

Why it matters

The cost of running dry

Hydration rarely disappears all at once. It slips through the day: a rushed morning, coffee before water, hours of focus, dry air, heat, movement, commuting, travel. By the time you notice it, you’re already playing catch-up.

And it isn’t only training that asks more from your body. Long workdays, Gulf heat, late nights, flights and simply being constantly on can all make staying hydrated easier to neglect.

VYTL was built for that daily reality: water and essential electrolytes, measured with purpose, so hydration becomes one less thing your day has to take from you.
