Bioavailable potassium form that also alkalises urine
We rank Potassium Citrate by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
Potassium Citrate is a salt made by combining potassium with citric acid. It is a bioavailable form of the mineral, meaning the body can easily absorb and use it. It also works to alkalise the urine, which means it increases the pH level to make the urine less acidic.
This ingredient is primarily used to ensure the body has enough potassium for healthy nerve and muscle function. Because it reduces acidity in the urine, it is often used to help prevent certain types of kidney stones from forming.
To create this supplement, manufacturers combine potassium hydroxide with citric acid in a controlled chemical reaction. This process results in a powder that is then dried and milled into a fine consistency. This powder is then either filled into capsules or pressed into tablets for sale.
The cost of this supplement is generally mid-range. This is because the raw materials are relatively easy to source, but the process of ensuring the powder remains stable and does not clump requires specific manufacturing standards.
