potassium citrate

Labeling varies. Common labeled values include elemental potassium amounts such as 90 mg and 99 mg, and other listings that show the salt amount (for example, 275 mg of potassium citrate). Some products list the capsule as providing 140 mg or 200 mg of potassium (labeling conventions vary by product).

Potassium citrate is often paired with magnesium, commonly presented as magnesium citrate, magnesium oxide, or magnesium glycinate alongside the potassium citrate.

Most products come as capsules or vegetarian/veggie capsules and commonly carry dietary labels such as gluten-free, non-GMO, and vegan/vegetarian.

Some labels report elemental potassium (for example, 90 mg or 99 mg), others report the salt amount as potassium citrate (for example, 275 mg of potassium citrate), and some listings show both by stating elemental potassium “from” a specified amount of potassium citrate.

Product labels show various combinations. Examples include 140 mg potassium paired with 70 mg magnesium, formulations listing 90 mg elemental potassium alongside 100 mg elemental magnesium, and products that list about 99 mg potassium with a magnesium total of 400 mg (labeling formats vary by product).
