Potassium 99 mg Tablets

Potassium 99 mg tablets provide 99 mg of elemental potassium as potassium citrate — the standard single-tablet dose for a food supplement. One a day, 90 tablets, a three-month supply.

What potassium does in the body

Potassium is the main positive ion inside cells, and the gradient it forms against sodium outside the cell is what makes nerve signals and muscle contraction possible. Potassium contributes to the normal functioning of the nervous system, to normal muscle function and to the maintenance of normal blood pressure. Sodium and potassium work as a pair: modern diets are heavy on sodium from processed food and light on potassium, which comes from vegetables, fruit, legumes and potatoes.

Why the dose is 99 mg

The daily requirement is around 3500 mg, and no tablet can carry that — a supplement is a top-up, not a source. 99 mg per tablet is the limit applied to potassium in supplements for good reason: a large single dose of potassium salt can irritate the gut and, in anyone whose kidneys are not clearing potassium normally, raise blood potassium. The bulk of your intake should keep coming from food; this tablet covers the shortfall on days when it does not.

Who it suits — and who should not take it

People eating few vegetables and fruit, anyone on a low-carbohydrate or ketogenic diet (where potassium losses rise), and those who sweat heavily in training or heat. Do not take potassium supplements if you have kidney disease, or if you take potassium-sparing diuretics, ACE inhibitors, angiotensin-receptor blockers or NSAIDs long term, without asking your doctor first — these all reduce potassium excretion. Magnesium is the partner electrolyte: the cell cannot hold potassium properly when magnesium is low, so magnesium bisglycinate is usually the more useful place to start.

How to take potassium tablets

One tablet a day with a meal and a full glass of water — potassium salts on an empty stomach can cause nausea. Do not exceed one tablet a day unless a doctor has told you to.

Questions people ask

Why so little potassium per tablet?

Because supplement doses of potassium are capped for safety. Food is the realistic source; the tablet is a top-up.

Is it an electrolyte for training?

It covers part of the picture. Sodium and magnesium are the other two electrolytes lost in sweat.

Can I take it with other minerals?

Yes, potassium does not compete with them for absorption. See all minerals.

Good to know. Do not exceed the recommended daily dose. Food supplements should not replace a varied, balanced diet and a healthy lifestyle. Talk to your doctor before use if you are pregnant, breastfeeding, taking medication or have a medical condition. Keep out of reach of children. Store in a cool, dry place away from direct sunlight.
