Potassium Supplements in the UK

Potassium contributes to normal muscle function, normal nervous system function and the maintenance of normal blood pressure. The NHS puts adult needs at 3,500mg a day, which most people get from food. This range includes NOW Foods, Swanson, Nutricost and BulkSupplements.

Buying guide and FAQs

What to compare

Forms include citrate, gluconate and aspartate. Compare the elemental potassium per serving, as many capsules provide 99mg, which is a small part of daily needs. Powders can provide more per serving.

How much is too much?

The NHS says 3,700mg or less a day from supplements is unlikely to cause obvious harm, but older people may be more affected by high amounts.

Who should not take potassium without advice?

Speak to your doctor first if you have kidney problems or take blood pressure medicines or some diuretics, as levels can become dangerously high.

Also browse: Magnesium, Hydration & Electrolytes, Calcium Supplements

All prices are in GBP, with free standard UK delivery.

Food supplements should not replace a varied, balanced diet and a healthy lifestyle. This page is general information, not medical advice. Always read the label, and speak to your doctor or pharmacist if you are pregnant, breastfeeding, taking medication or have a medical condition.
