Description
Potassium Citrate Mixture is a fast-acting urinary alkaliniser used to relieve the painful symptoms of cystitis and other mild urinary tract infections (UTIs). It works by reducing urine acidity, which can ease burning and stinging when passing urine. If you want to buy potassium citrate mixture online in the UK, choose a reputable provider and follow the dosing instructions carefully.
What Is Potassium Citrate Mixture?
Potassium citrate is an alkalinising agent. In a mixture form, it is taken diluted with water to help make urine less acidic. Less acidic urine can be less irritating to the bladder and urethra, which may reduce discomfort while you recover.
Cystitis Symptoms Potassium Citrate May Help With
You may consider potassium citrate mixture if you have:
- Pain, burning, or stinging when urinating
- A frequent urge to pass urine
- Cloudy, dark, or strong-smelling urine
- Pain or pressure low in the abdomen
- Feeling tired, achy, or generally unwell
Important: Symptom Relief Only
Potassium citrate mixture helps relieve symptoms by alkalinising urine. It does not kill bacteria. If symptoms persist, worsen, or recur frequently, seek medical advice. Some cases require assessment and antibiotics.
How Potassium Citrate Works
Neutralises Excess Urine Acidity
Potassium citrate helps neutralise excess acid in urine, making it more alkaline. This can reduce bladder irritation and help ease pain and burning sensations when passing urine.
Other Uses Under Medical Guidance
Under medical supervision, potassium citrate may also be used for conditions such as renal tubular acidosis and to help prevent certain kidney stones.
