What Is Potassium Citrate?
Potassium Citrate Mixture is a gentle, fast-acting treatment designed to relieve the painful symptoms of cystitis and other mild urinary tract infections (UTIs).

You may benefit from Potassium Citrate Mixture if you experience:
-
Pain or stinging when urinating
-
Frequent urge to pass urine
-
Cloudy, dark, or strong-smelling urine
-
Pain low in the abdomen
-
Feeling tired, achy, or generally unwell

How Potassium Citrate Works
Potassium Citrate helps neutralise excess acid in the urine, making it more alkaline. This:
-
Reduces irritation in the bladder
-
Eases pain and burning sensations
-
Supports faster recovery from cystitis symptoms
It can also be used under medical guidance to help treat renal tubular acidosis and prevent kidney stones.
