Why supplement?
Marked asPrimarySupporting
Maintains neuromuscular excitability
Aspartate is an endogenous amino acid. After potassium dissociates it enters the sodium-potassium pump path, maintaining resting potential and muscle repolarization. Endurance-exercise electrolyte formulas after sweating commonly use this salt; the aim is sending potassium back to cells as an amino-acid salt.
Helps maintain blood pressure
Potassium promotes urinary sodium excretion and relaxes vascular smooth muscle. Sports drinks and electrolyte powders use potassium aspartate as a soluble potassium source. Blood pressure and vascular tone still depend on released potassium ions; people managing blood pressure look to this cation.
Which symptoms may ease?
Muscle cramps
Aspartate is an endogenous amino acid. 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 aspartate binds potassium with an amino-acid ligand, common in sports electrolyte formulas; the active agent is still the potassium ion. 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 aspartate binds potassium with an amino-acid ligand, common in sports electrolyte formulas; the active agent is still the potassium ion. 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.
