KSPtabs at the AUA

In the News

In May 2019 the KSPtabs team headed to Chicago for the American Urological Association Annual Meeting, the largest gathering of urologists in the world. It was the first time we put KSPtabs in the hands of the physicians who treat kidney stones every day, and the response told us we were onto something.

The Expo

Sharing KSPtabs with the urology community

The AUA has more than 18,000 members: urologists, physician assistants, nurse practitioners, nurses and the teams around them, all focused on the kidneys, bladder and urinary system. Proper hydration is a vital part of urological health, and KSPtabs was developed to give patients a hydration tool that supports it. The AUA Expo was where we got to make that case to the people who'd be recommending it.

"The KSPtabs team shared our message and products with the attendees during the AUA Expo. We distributed over 1,000 tubes of KSPtabs, and we were overwhelmed by the positive response we received from the urological community."

The Idea

Where KSPtabs came from

KSPtabs was developed by board-certified urologist Michael Trotter, M.D. The idea came to him while visiting with a friend who was also a patient. His friend asked, "Why don't you invent something I can easily take every day to reduce my risk of forming kidney stones?" That was all it took. Dr. Trotter set out to build an effervescent tablet that would deliver the minerals stone formers need and make regular hydration something people would look forward to. The full story ran in the Austin American-Statesman the year before the AUA.

KSPtabs was built for stone prevention, but it works just as well for anyone with an active lifestyle. The electrolytes in each tablet support muscle recovery and everyday hydration, without the sugar and salt of a sports drink.

What we told the urologists

115 mEq of alkalinizing agents per tablet.

2Hydration and stone inhibitors in one glass.

3Easy enough that patients keep doing it.

Each tablet delivers 15 mEq of alkalinizing agents that support healthy urine chemistry and help reduce calcium crystal saturation, the building blocks of kidney stones. Your body doesn't store these minerals, so daily intake is what keeps them working.

The Formula

What's in KSPtabs

Ingredient What it does
Potassium citrate A potent inhibitor of urinary crystal formation. Added citrate supports a normal urinary pH and reduces calcium crystal saturation
Magnesium citrate Helps maintain normal urine parameters by binding to oxalate in the urine
Vitamin B6 As pyridoxal-5-phosphate, a well-absorbed form. Supports normal urine parameters and may help lower urinary oxalate
Bicarbonate An alkalizing agent that works with citrate to reduce calcium crystal formation. It's also what makes the tablet fizz
Avocado oil Binds the tablet
Stevia Plant-based sweetener, no added sugar, minimal calories
Natural colors Beet juice for Very Berry, riboflavin for Key Lime, vegetable juice for Sunrise Citrus

Since 2019: KSPtabs now comes in three flavors (Sunrise Citrus joined Very Berry and Key Lime), and two published studies have looked at its effect on urine chemistry. In 2026 the AUA updated its Medical Management of Kidney Stones guideline for the first time since 2014, and it now states that clinicians may offer over-the-counter alkali products, including effervescent formulations, to raise urinary pH and citrate in patients with calcium or uric acid stones (Statement 36). The full breakdown is on our Clinical Research page, and physicians can request patient samples on our Medical Professionals page.

Where KSPtabs Fits

Water gets boring. This doesn't.

Hydration is the single biggest lever against kidney stones, and the hardest habit to keep. KSPtabs dissolves in water or your favorite drink, tastes like something you'd choose, and carries the stone inhibitors with it. That was the pitch in Chicago, and it's still the pitch. What makes KSPtabs different has the longer version.

  • ✓Drop one tablet in 16 ounces of water, let it fizz, drink
  • ✓Citrate + electrolytes to support healthy urinary citrate levels
  • ✓33% increase in urinary citrate in a small clinical study*

*Median urinary citrate increased 33% during KSPtabs use. Small study in 10 healthy adults with no history of kidney stones; the study evaluated urine chemistry and did not assess kidney stone recurrence. Journal of Urology, 2021.

Common Questions

Questions urologists asked us

Is KSPtabs only for people who form kidney stones?

No. It was designed for stone formers, but it works as an everyday electrolyte drink for anyone: potassium and magnesium for hydration and muscle recovery, only a small amount of sodium, no added sugar. Athletes and people who work outdoors use it in place of sports drinks.

Can I recommend KSPtabs to my patients?

Yes. KSPtabs is an over-the-counter supplement developed by a practicing urologist, and physicians can request a sample box for their clinic on the Medical Professionals page. Many use it for patients who struggle with compliance on prescription citrate, with a follow-up 24-hour urine test to confirm the effect.

Why an effervescent tablet instead of a pill or powder?

Because the water is the point. A pill doesn't hydrate you, and a powder needs stirring and makes a mess. A tablet that fizzes in a glass ties the minerals to the habit stone formers most need, drinking more, and comes in a waterproof tube you can keep in the car or your desk.
