About KSPtabs

A urologist's answer to "drink more water."

KSPtabs is an effervescent citrate and electrolyte tablet developed by a practicing urologist in Austin, Texas, for the patients he saw every day: people who knew hydration and citrate matter for their kidney health and couldn't stick with the routine. Drop one in water, let it fizz, drink.

Our Story

It started with a question on a lake

Dr. Michael Trotter, board-certified urologist and developer of KSPtabs

Michael Trotter, M.D.Board-certified urologist, Midtown Urology, Austin. Developed KSPtabs.

On a hot summer day in 2012, Dr. Trotter was on Lake McQueeney with friends when one of them, a longtime kidney stone patient, asked the question that started all of this.

"Why don't you invent something I can easily take every day to support my kidney health?"

He already knew the basics in medical terms: more fluid, and citrate to support healthy urine chemistry. The problem was that the prescription version, large potassium citrate pills several times a day, was something most of his patients quit within months. So he set out to build a version people would keep taking: the minerals that matter, pressed into a tablet that dissolves in water, tastes good, and lives in a tube you can carry anywhere. He still practices at Midtown Urology in Austin, and KSPtabs is still a small, family-run company based there.
