Potassium acid phosphate
Potassium acid phosphate is an oral supplement and urinary acidifier. By increasing urine acidity, it helps prevent the precipitation of calcium stones and enhances the efficacy of certain urinary tract antibiotics. It also provides potassium and phosphate ions, which are essential for maintaining physiological cellular functions and bone health.
