Potassium is an essential mineral that contributes to normal muscle function, the normal functioning of the nervous system, and the maintenance of normal blood pressure. If you eat plenty of fruit and vegetables you'll usually get all you need – but with many of us not managing our five-a-day, and a growing share of our diets coming from highly processed foods, it's easy to fall short of the recommended intake.
If that sounds like you, a supplement can help top up your levels. Potassium is found in a wide variety of foods, most of them plant-based, and it's available as a supplement in several forms – from vegetarian capsules to electrolyte liquids and mineral sachets. It's also one to be sensible about dosing, so it's worth understanding how much you need before you start.
