Are there potassium supplements without sodium additives?

Are there potassium supplements that avoid sodium additives?

Yes, many potassium supplements contain no added sodium. Most standard potassium chloride tablets and capsules list only the active ingredient and fillers like microcrystalline cellulose or magnesium stearate, with no sodium chloride or sodium-based preservatives.

Potassium gluconate and potassium citrate products follow the same pattern. Manufacturers formulate these versions for patients who need to restrict sodium intake, such as those managing hypertension or heart failure.

What potassium forms avoid sodium?

Potassium chloride tablets from generic manufacturers typically contain 8 mEq, 10 mEq, or 20 mEq of potassium with no sodium.
Potassium gluconate tablets or capsules provide 99 mg elemental potassium per dose and are sodium-free.
Potassium citrate extended-release tablets supply 10 mEq or 20 mEq potassium and list no sodium ingredients on their labels.

Which brands skip sodium entirely?

Major retailers sell store-brand potassium chloride and potassium gluconate that show zero sodium on the Supplement Facts panel. Prescription extended-release potassium chloride (Klor-Con, K-Dur) also contains no added sodium. Users checking the label for “sodium” or “NaCl” will find these products clean.

How do sodium-free options compare with regular supplements?

Sodium-free versions deliver the same elemental potassium as products that may contain trace sodium from manufacturing. The difference appears only when a product explicitly adds sodium chloride as a filler or stabilizer, which is rare in current formulations. Patients following a low-sodium diet can use either type if the label confirms zero added sodium.

When should you check the label for sodium?

Always verify the Supplement Facts or drug facts panel. Even sodium-free potassium products may carry a warning for patients with kidney disease or those on potassium-sparing diuretics. Pharmacists can confirm the exact sodium content of any specific bottle if the printed label is unclear.
