One in ten people get a kidney stone. Most get another one within five years.
We built a system of three products to help. It works the way doctors actually handle stones — by raising citrate, lowering oxalate, and keeping you hydrated.
"I built LithoLyte because patients deserved a real solution — not another supplement."
It starts long before the pain.
A kidney stone doesn't appear overnight. It builds, quietly, over weeks or months. Understanding the four stages is the first step to stopping it.
When you don't drink enough fluids, your urine gets thick with minerals like calcium and oxalate. Think of it like adding too much sugar to a glass of tea — it stops dissolving.
Those minerals start to clump into microscopic crystals. Most people pass these without ever noticing. The trouble starts when crystals stick together.
Without enough citrate to break them up, crystals bind into solid stones. Some stay tiny. Others grow until they get stuck in a narrow part of your urinary tract.
A stuck stone sets off pain often described as worse than childbirth. Most pass on their own — but 1 in 4 need a medical procedure to remove them.
The good news: stones are preventable. The next sections show you how.
If any of these sound like you, listen up.
Stones don't pick favorites — but they do pick patterns. These are six big risk factors urologists see in patients who form stones over and over again.

Without citrate
Crystals stick together. Stones grow.
With citrate
Citrate coats crystals. Stones can't form.
The amount of citrate doctors recommend per day to keep urine balanced.
Section 03 · The Science
And most people don't have enough of it.
Citrate is a tiny molecule derived from citrus fruits. It does two things stones hate: it grabs onto calcium so it can't form crystals, and it raises your urine's pH so existing crystals stay dissolved.
People who form stones often have low urinary citrate. Raising it back to normal levels is ideal.
From citrus, by design
Citrate is the same molecule that makes lemons taste tart.
Doctors have known for decades that people who drink lemon juice form fewer stones. The active ingredient is citrate — naturally found in lemons, limes, and oranges.
But you'd need to drink the juice of 10 whole lemons a day to hit a clinical 10 mEq dose. LithoLyte gives you the same citrate — in one tasteless stick.
Section 04 · Prevention
Every guideline from the American Urological Association uses these levers. Move any one of them in the right direction and your risk drops. Move all three and you change the math entirely.
Stones form when urine gets too concentrated. Drinking enough fluids with citrate keeps minerals from clumping. Doctors recommend at least 2.5 liters of urine output daily — about 3 liters of fluids in.
Citrate is the molecule that stops crystals from sticking together. Stone-formers usually run low. Replacing it brings urine chemistry back to normal — and keeps it there.
Oxalate is in spinach, nuts, beets, and chocolate — and it's a common ingredient in stones. Now you can stop it from getting absorbed.
Section 05 · The System
Most people start with LithoLyte. Then layer in what they need.
The three products map directly to the three pillars. You don't need all three to start — but optimizing all three will enhance performance.
All Three Pillars
Hydration. Citrate. Oxalate. Covered.
When you address all three pillars at once, your urine chemistry shifts in your favor — and stays there. Stack the system and start your day knowing every lever is being pulled.
Section 06 · Why us
Most aren't built by a doctor at all.
Walk into any store and you'll find a wall of supplements. Almost none of them deliver a clinical dose. Almost none are formulated by anyone who treats stones for a living. We built LithoLyte to close that gap.
"I watched the same patients come back, year after year, with the same issues. The supplements they were buying weren't doing anything. So we made one that does."
Section 07 · Personalized
A 24-hour test shows exactly which pillars you need.
No two stone-formers are the same. Some have plenty of citrate but eat too much oxalate. Some are simply dehydrated. A urine panel tells you — and your doctor — which lever to pull.
Reading your results
You're not drinking enough fluids with citrate.
Your diet is the trigger.
Always work with your doctor to interpret a 24-hour urine test. LithoLyte is not a substitute for medical care.
Your next step
One stick a day. That's the whole routine.
