What is in it
The only active ingredient is potassium citrate. 99 mg is the standard strength for potassium capsules.
How 99 mg compares. It is a small top-up. The adequate intake for adults in the Australian and New Zealand Nutrient Reference Values is 2,800 mg a day for women and 3,800 mg a day for men. One banana has roughly 400 mg, and potatoes, beans, yoghurt and leafy greens are all good sources. For most people, food does far more for potassium intake than a capsule.
Who it suits
- Adults who want a small, measured potassium top-up on the advice of a health professional.
- People who want potassium in the citrate form.
Who should check first
- Kidney disease: do not take potassium supplements unless your doctor tells you to.
- Blood pressure or heart medicine: ACE inhibitors, sartans and potassium-sparing fluid tablets such as spironolactone raise potassium levels. Do not add a potassium supplement without your doctor's advice.
- Using salt substitutes: many are potassium based, so count them too.
- Pregnant or breastfeeding: check with your doctor first.
How to use it
Follow the directions on the label and do not take more than it says. Take it with food and a full glass of water to be gentle on the stomach.
