Kidney Stone Prevention Protocol.

Adjunctive support for people with a history of calcium oxalate stones, focused on citrate, mineral timing, and oxalate metabolism. It must be paired with clinician evaluation, stone analysis, urine testing, hydration, and diet guidance; avoid high-dose vitamin C.

In short

The kidney stone prevention protocol in brief.

A quick summary. The full stack, with dose and timing for each supplement, is below.

The Kidney Stone Prevention Protocol is an advanced stack of 4 supplements aimed at kidney health: Magnesium Citrate, Calcium, Potassium, and Vitamin B6. 2 are core and the rest are optional add-ons, at roughly $15-35/mo. Each supplement below lists its dose, timing, role, and the evidence behind it.

The stack

What is in the kidney stone prevention protocol.

Dose, timing, role, and evidence tier for each supplement. Core items carry the protocol; optional ones are situational. Open any name for the full profile.

Magnesium Citrate

Magnesium can bind intestinal oxalate and citrate may support a less stone-forming urine profile, but response depends on the person and should be checked against 24-hour urine results.

Calcium

Normal calcium intake with meals helps bind oxalate in the gut, while low-calcium diets can raise oxalate absorption. This is meal-timing support, not a reason to exceed calcium targets.

Potassium

Clinician-guided potassium alkali can raise urinary citrate in some stone formers, but potassium supplements can be unsafe with kidney disease or certain medications. Do not self-start high-dose potassium.

Vitamin B6

Vitamin B6 is involved in glyoxylate metabolism and may be most relevant when oxalate is high, but chronic high-dose B6 can itself cause neuropathy. Keep dosing conservative and lab-guided when possible.

Why it works together

How the pieces combine.

The mechanistic rationale for stacking these together rather than taking them in isolation.

  • Hydration, sodium reduction, stone analysis, and 24-hour urine testing are the foundation; supplements should be chosen from the urine pattern.
  • Calcium belongs with meals that contain oxalate, while Magnesium Citrate is often better tolerated with the evening meal.
  • Avoid high-dose Vitamin C in stone formers because it can raise urinary oxalate.
