How KSPtabs Works

Citrate + hydration
work together

Citrate and hydration both shape urinary chemistry. See the science — and how KSPtabs delivers both in one daily routine.

How kidney stones can form

Kidney stones can form when stone-forming substances become highly concentrated in urine.

1

Urine becomes concentrated

When fluid intake is too low or fluid loss is high, urine can become more concentrated.

2

Crystals begin to form

Stone-forming substances can crystallize when their concentration becomes high enough.

3

Crystals may grow

Crystals can collect and grow into a kidney stone.

Common types of kidney stones

  • Calcium oxalate
  • Calcium phosphate
  • Uric acid
  • Struvite
  • Cystine

Where citrate comes in

Citrate is a naturally occurring substance found in urine. It interacts with calcium and other stone-forming substances and plays an important role in urinary chemistry.

Adequate urinary citrate is associated with a urinary environment less favorable to stone formation.
Diagram of how citrate works in urine: it binds free calcium, slows crystal growth, reduces crystal clumping, and inhibits crystal formation.

Citrate interacts with calcium in urine and influences how stone-forming substances behave.

Why hydration matters

More fluid helps keep stone-forming substances less concentrated in urine.

Adequate fluid intake is an important part of maintaining a less-concentrated urinary environment.

What the study showed

Low urinary citrate is among the most common findings in metabolic stone evaluation.

urinary citrate*

In a prospective crossover study, median urinary citrate rose from 597 to 797 mg/day and urine pH from 6.46 to 6.86 during KSPtabs use.

The bigger picture

Citrate and hydration are only part of a kidney-stone-conscious routine. Diet, overall health, and guidance from your healthcare professional also play an important role.
