Sodium’s partner. It works mostly inside your cells, where it helps nerves send signals and muscles contract.

What it does.
Figures marked with an asterisk link to their sources at the foot of the page.
Most of your body’s potassium sits inside your cells, while most of its sodium sits outside them*1. The difference between the two holds an electrical charge across every cell membrane, and your nerves and muscles use that charge to send signals and contract.
European food regulators accept that potassium contributes to normal muscle function, to the normal functioning of the nervous system and to the maintenance of normal blood pressure*2.
You lose far less potassium in sweat than sodium: typically about 2 to 8 mmol per litre, against 10 to 90 mmol for sodium*3.

Bananas
Banana plants draw potassium up from the soil through their roots and store it in the fruit, which is how bananas became the best-known potassium food. A litre of bev. gives as much potassium as about 70 g of banana, without the 8.5 g of sugar and 62 kcal that come with it*4.
How much is in bev.
Made up as directed, bev. carries about 6.4 mmol of potassium per litre. That sits inside the 2 to 8 mmol per litre found in sweat*3, so bev. carries potassium at the kind of strength your body loses it.
It arrives alongside 600 mg of sodium, so the two partners travel together in every glass.
All of it comes with zero sugar and zero calories in the prepared drink. One squeeze into a bottle of water and it is ready, with no tablets to dissolve.
Where it comes from.
It comes from three salts. Potassium bicarbonate gives the most, and potassium chloride and tripotassium citrate monohydrate add the rest.

| Potassium bicarbonate | 332 mg | 130 mg |
| Potassium chloride | 122 mg | 64 mg |
| Tripotassium citrate monohydrate | 155 mg | 56 mg |
