Potassium contributes to the maintenance of normal blood pressure and normal muscle and nervous system function (EFSA-authorised claims); a BMJ meta-analysis links a higher potassium intake to healthier blood pressure, especially with a salty diet.

| Frequency | 1–2 times daily |
Best forms to choose
Potassium citrate in capsules or powder; the citrate form is gentle on the stomach.
