Lemon juice is one of the simplest and cheapest home remedies for kidney stone prevention. The reason is its high content of natural citrate.
Why citrate is so important
Citrate binds calcium in the urine and prevents calcium oxalate crystals from clumping together. People with low urinary citrate have a much higher stone risk – exactly where lemon juice helps.
Practical use
- Juice of ½ lemon in a glass of water, several times a day
- Or quality lemon juice concentrate/powder on the go
- Spread it across the day, not all at once
Caution & when to see a doctor
The acid can erode tooth enamel – dilute with water and use a straw if needed. With a sensitive stomach or reflux, dose carefully. Acute renal colic needs medical care.
