The listings show several potassium compound forms: potassium phosphate, potassium citrate, potassium aspartate, potassium gluconate, and potassium iodide.
They commonly describe support for nerve impulses and muscle contraction, electrolyte and fluid balance, heart and cardiovascular function, and general organ or metabolic processes.
Instructions vary by product: examples include taking 4 tablets per day, 1 capsule once or twice daily with meals, 2 capsules per day in divided doses, or one tablet daily. One potassium iodide product lists a short-term two-tablet adult dose.
Common warnings include consulting a doctor if pregnant or nursing, if you take prescription medications, or if you have medical conditions; many products are labeled for adult use only and advise keeping supplements out of reach of children or consulting a clinician about electrolyte or fluid restrictions.
The listings show potassium offered as tablets, caplets, and capsules (including vegetarian/vegan capsule options).
