Potassium Citrate

Our clean Potassium Citrate supplement supports normal blood pressure, muscle function, and the nervous system. Given the low intakes of potassium in the UK, our fully reacted Potassium Citrate offers an easy and effective way to boost your intake of this vital mineral. Free from nasty additives, it is gentle on the stomach and highly absorbed.

Potassium is also beneficial for alkalizing urine, which can help reduce the risk of adverse health outcomes associated with acidic urine and high uric acid levels.

Here's an overview of the key health benefits associated with Potassium Citrate:

Kidney Health: Potassium citrate is often used to help prevent kidney stones. It helps reduce the formation of stone-causing crystals in the urine by increasing urinary pH levels, making it harder for stone formation. Regular intake can help lower the risk of certain types of kidney stones [1].

Cardiovascular Health: Potassium plays a crucial role in maintaining a healthy cardiovascular system. It helps regulate blood pressure by balancing the effects of sodium. This helps reduce the risk of hypertension and related conditions such as heart disease and stroke. By aiding in the dilation of blood vessels, potassium citrate can contribute to better blood flow and heart health [2].

Muscle and Nerve Function: Potassium is essential for the proper function of muscles and nerves. It helps in muscle contraction and relaxation, including those of the heart muscle, contributing to normal heart rhythm. For nerve function, potassium is critical for transmitting signals that control various bodily functions, including movement, sensation, and reflexes.[3]

Acid-Base Balance: Potassium citrate has an alkalising effect on the body, which can help correct metabolic acidosis (a condition where the body produces too much acid or when the kidneys are not removing enough acid from the body). This is important for maintaining the body's optimal pH balance, supporting overall metabolic health, and preventing various metabolic disorders [4].

Bone Health: Potassium plays a role in preserving bone mineral density. It helps neutralise metabolic acids, which can leach calcium from bones, leading to osteoporosis over time. Adequate intake of potassium can indirectly support bone health by preserving calcium stores in bones [5].

Different forms of potassium offer different benefits. Someone might choose potassium citrate over other forms like potassium chloride, gluconate, acetate, or phosphate due to its specific benefits in preventing certain types of kidney stones and managing metabolic acidosis.

Potassium citrate effectively alkalises urine, reducing the risk of stone formation and assisting in the management of acid-base balance.

Its unique action, especially in urinary tract health, makes it a preferred choice for those specific health conditions, where the other forms might be used for general potassium supplementation or other specific health needs. (6)

Almost anyone can benefit from Potassium Citrate. However, individuals who are prone to developing certain types of kidney stones, especially calcium oxalate stones, as it helps to alkalise urine and reduce stone formation.

Those looking to normalise blood pressure may also benefit from taking potassium citrate.

Additionally, those with metabolic acidosis, a condition characterised by excessive acidity in the body, may find potassium citrate beneficial for neutralising acid levels.
