- Urine pH is an important factor in the production of kidney stones.
- Uric acid, cystine, and calcium oxalate stones tend to form in acidic urine
- whereas struvite (magnesium ammonium phosphate) and calcium phosphate stones form in alkaline urine.
- Urine should be acidified for prevention of calcium phosphate and struvite stones.
- Cranberry juice or betaine can lower urine pH.
