Why supplement?
Marked asPrimarySupporting
Lowers kidney-stone risk
Citrate is metabolized in the body to bicarbonate; urinary citrate rises and calcium-salt crystals are less likely to precipitate. Calcium-stone prevention trials in hypocitraturia mostly use this salt. Fruit-and-vegetable potassium also often exists as citrate; people with recurrent stones look to this anion.
Supports bone mineral retention
Alkali load in older-adult trials has been linked to lower bone-turnover markers, with bone less often mobilized to buffer dietary acid. Potassium citrate raises urinary citrate and whole-body alkali reserve together; people who want to keep bone mineral look to this organic-anion path.
Helps maintain blood pressure
Potassium itself maintains membrane potential, helps the kidney excrete sodium, and relaxes vascular smooth muscle. Potassium citrate sends potassium ions together with a metabolizable organic anion. People managing blood pressure who also want a food-like potassium anion often choose this salt to put potassium back.
Which symptoms may ease?
Muscle cramps
Citrate is metabolized in the body to bicarbonate; urinary citrate rises and calcium-salt crystals are less likely to precipitate. 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
Potassium itself maintains membrane potential, helps the kidney excrete sodium, and relaxes vascular smooth muscle. 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
Potassium itself maintains membrane potential, helps the kidney excrete sodium, and relaxes vascular smooth muscle. 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.
