Tag: Potassium in water

Trace amounts of potassium are typically found in both tap and bottled water, with concentrations varying widely based on the water source and treatment process. This guide will explain how and why does drinking water contain potassium, and whether it contributes meaningfully to your daily nutritional intake.

Drinking water's contribution to potassium intake is negligible, according to the National Institutes of Health (NIH). Water, whether tap or bottled, can contain potassium, though concentrations vary based on the source and treatment.

According to scientific studies, the potassium content in bottled water can range significantly, from negligible amounts up to 18 mg per liter, confirming that bottled water does contain potassium, but in highly variable quantities. This variation depends heavily on the water's source and how it has been processed and prepared for bottling.

The average concentration of potassium in household tap water is around 2.15 mg/liter, confirming that waters do contain potassium, but in very small amounts. This essential mineral is present in varying concentrations depending on the water source and any treatment processes applied.

For most healthy individuals, the amount of potassium in tap water is negligible compared to dietary intake, contributing less than 1% of the daily total. So, is tap water high in potassium? The truth depends on several factors, including your specific water source and whether you use a water softener.
