Hydration with a Purpose

Everyday hydration,
with citrate built in.

KSPtabs combines citrate + magnesium with electrolytes in a zero-sugar, lower-sodium effervescent tablet — developed by a urologist for hydration that fits into real life.

Why KSPtabs Is Different

Hydration is
more than sodium.

Sodium plays an important role in hydration, especially when you're losing a lot through sweat. But everyday hydration doesn't always call for an ultra-high-sodium formula.

KSPtabs takes a different approach: citrate + electrolytes, including potassium and magnesium, in a zero-sugar formula designed for everyday hydration, workouts, travel, heat and life on the go.

Most people already get plenty of sodium through everyday foods, so for daily hydration, adding a high-sodium drink on top may simply not be necessary.

And because KSPtabs was originally developed by a urologist, citrate isn't an afterthought — it's part of the reason the formula exists.

K
Potassium
An essential electrolyte involved in fluid balance, normal muscle contraction and nerve function.
Cit
Citrate
A defining part of the KSPtabs formula. In a small clinical study, KSPtabs use was associated with a significant increase in urinary citrate.*

Mg
Magnesium Citrate
Involved in over 300 enzyme reactions — including muscle contraction and relaxation, which is why adequate magnesium is associated with reduced cramping. Also supports nervous system regulation and a calmer stress response.
B6
Vitamin B6
Supports normal metabolism through its role in more than 100 enzyme reactions.
Different Hydration Needs

Different hydration needs call for different formulas.

Hydration isn't one-size-fits-all. Sodium needs can vary based on your activity, climate and diet. KSPtabs offers a lower-sodium, zero-sugar, citrate-forward formula for everyday and active hydration.

Formula Type Sodium* Sugar* Best For
Higher-sodium endurance formulas 600–1,000+ mg 0–40+ g Heavy sweat, long-duration endurance exercise
Rapid-rehydration formulas 250–600 mg 0–15 g Rapid rehydration, travel, dehydration recovery
KSPtabs 170 mg 0 g Everyday hydration, workouts, travel, heat & active lifestyles

*Per serving. Values vary by brand and product.
