Curated, not stocked.
We include this because potassium deficiency is frequently underappreciated — it rarely shows up as a dramatic symptom until it's significant. Pure Encapsulations uses a clean citrate form with minimal excipients, which suits patients with sensitivities. Our doctors most commonly suggest it after a blood panel flags low-normal serum potassium, or where dietary intake is demonstrably poor, rather than as a routine add-on for everyone.
About this product
Potassium (citrate)
Potassium (Citrate) by Pure Encapsulations is a mineral supplement providing potassium in its citrate form — a well-absorbed organic salt that pairs the mineral with citric acid to support tolerability and uptake compared with some inorganic alternatives.
Potassium is an essential electrolyte. It sits at the centre of fluid balance, nerve signalling, and the electrical activity that keeps the heart beating in a regular rhythm. Skeletal muscle contraction — including the kind that matters during exercise or recovery — also depends on adequate potassium status. Low dietary intake is common, particularly in people eating a processed-food-heavy diet with insufficient fruit and vegetables.
This supplement suits people who have confirmed low potassium through blood testing, those with higher losses through sweat (endurance athletes in heavy training), and individuals whose clinician has flagged borderline intake as a contributing factor in fatigue or muscle cramping. It is not a replacement for a potassium-rich diet, but it can help close a documented gap.
Pure Encapsulations is a brand with a longstanding reputation for clean, minimal formulations with few excipients. Their range is routinely recommended by clinicians who want a straightforward supplement without unnecessary additives. The citrate form also contributes to a mildly alkaline urinary environment, which is studied in the context of kidney stone prevention in susceptible individuals.

How to use
Follow the dosage on the packaging. Based on the product label, one capsule taken one to two times daily is the suggested intake — take with food to minimise any gastric discomfort. Do not exceed the stated dose without guidance from a clinician, as excess potassium carries specific risks.

Common questions
Frequently asked
Do I need a blood test before taking this?
It is strongly advisable. Potassium levels outside the normal range — in either direction — carry cardiovascular risks. A blood panel confirms whether supplementation is appropriate and at what level. Do not self-supplement at higher doses without medical guidance.
Is potassium citrate safe to take with blood pressure medications?
Some antihypertensives — particularly ACE inhibitors, ARBs, and potassium-sparing diuretics — can raise serum potassium independently. Combining them with a potassium supplement increases the risk of hyperkalaemia. Always check with your prescribing clinician before starting this product if you are on any of these drug classes.
How is potassium citrate different from potassium chloride?
Both deliver elemental potassium, but the citrate salt is generally better tolerated on the stomach and has a mildly alkalinising effect on urine. Potassium chloride is the form more commonly used in food fortification and some medications. For a daily supplement, citrate is often the preferred clinical choice.
How long before I notice a difference?
If low potassium is contributing to symptoms such as fatigue or muscle cramps, some people notice an improvement within one to two weeks of consistent use. The clearest way to confirm improvement is a follow-up blood test, which your clinician can arrange.
Who should avoid this supplement?
People with kidney disease or impaired kidney function should not take potassium supplements without close medical supervision, as the kidneys regulate potassium excretion. It is also not suitable for those with hyperkalaemia or taking medications that raise potassium levels, unless directed by a doctor.
