Potassium
206mg
Most of us are under-consuming this mineral. It supports your muscles and helps keep your fluids balanced. Potassium and sodium work in tandem, so getting the balance between the two right really matters.
Sodium
222mg
The mineral we're getting plenty of! When you think about it, most of us are eating salt throughout the day, so don't overdo it. But sodium does help your body hold onto fluid and stay hydrated, so it's an absolute must on those extra-sweaty days.
