How Unstone-B6 Tablet works

This combination helps prevent the formation of kidney stones by reducing the factors that lead to stone buildup in the urinary tract. Potassium and magnesium citrate increase urinary citrate levels and make the urine less acidic, which helps stop stone-forming minerals from sticking together. Vitamin B6 (pyridoxine) helps reduce excess oxalate in urine, a common cause of stone formation. Together, these actions lower the risk of new stone formation and support kidney health.
