Compare every Potassium product across UK retailers on Suppio, ranked by true value - price per active dose, not pack size. Prices refreshed daily.
Electrolyte essential for heart and muscle function
We rank Potassium by price per 2000mg - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
What it is
Potassium is an electrolyte, which is a mineral that carries an electrical charge when dissolved in body fluids. It is a vital nutrient that helps the body maintain a healthy balance of water and salts.
Why it's used
It is primarily used to support the proper functioning of the heart and the muscles. This includes ensuring the heart beats at a regular rhythm and helping muscles contract and relax correctly.
How it's made
To create the supplement, potassium is combined with other molecules to create a stable salt. This resulting compound is then processed into a fine powder, which is either packed into capsules or pressed into tablets for sale.
What it typically costs
This ingredient is generally mid-range in price. This is because the raw materials are widely available and the manufacturing process is straightforward, but there is still a need for high purity standards to ensure safety.

Does it actually differ?
Potassium
An essential element and mineral found in foods like fruits, vegetables, and meat.
It is used to regulate electrolyte balance, blood pressure, and the electrical impulses that make nerves and muscles work.
The provided text does not list specific evidence comparing general potassium to potassium citrate.
Potassium Citrate
A specific salt form of potassium.
It may be used to improve bone health and metabolism in older adults.
The provided text mentions it may improve bone health and metabolism, but does not provide a direct comparison of effectiveness against other forms.
Verdict: There is not enough comparative evidence in the text to suggest that potassium citrate is worth paying more for than general potassium.
