Why supplement?
Marked asPrimarySupporting
Helps maintain blood pressure
Reduced-sodium salts replace part of table salt with potassium chloride, keeping a salty taste while sending potassium into cooking. Potassium promotes urinary sodium excretion and relaxes vascular smooth muscle. Most potassium repletion in adult blood-pressure trials is this chloride salt; people managing blood pressure meet it most often.
Maintains neuromuscular excitability
The sodium-potassium pump drives potassium into cells, creating resting potential; repolarization depends on potassium leaving through channels. Heavy sweating loses potassium in sweat; potassium chloride puts this intracellular cation back so calf twitching and weakness follow less often.
Which symptoms may ease?
Muscle cramps
The sodium-potassium pump drives potassium into cells, creating resting potential; repolarization depends on potassium leaving through channels. People whose calves seize at night or whose muscles stay hard after training more often notice fewer cramps and less morning leg ache after several continuous weeks.
High blood pressure symptoms
Reduced-sodium salts replace part of table salt with potassium chloride, keeping a salty taste while sending potassium into cooking. People with heavy heads and tight necks in the morning and higher readings more often notice the numbers and a clearer head after several continuous weeks.
Which conditions may it support?
Hypertension
Reduced-sodium salts replace part of table salt with potassium chloride, keeping a salty taste while sending potassium into cooking. People with high home readings and a heavy, tight neck more often notice the numbers and a clearer head after several continuous weeks.
How to take it?
Potassium supplement doses are usually low; do not treat low blood potassium yourself with salt substitutes.
How oftenGet it mainly from food; use supplements only as a clinician directs.
What to watch
Cautions
People with kidney or heart disease or on ACE inhibitors/ARBs/potassium-sparing diuretics must not self-supplement potassium.
Hyperkalemia can cause dangerous arrhythmias.
Interactions
- ACE inhibitors/ARBs, potassium-sparing diuretics, aldosterone antagonists (hyperkalemia)
- Do not stack on prescribed potassium
· Stomach discomfort
· Nausea
· High blood potassium can cause muscle weakness and heart-rhythm problems.
Long-term dependenceNot addictive; buildup with impaired kidney function can cause high blood potassium.
