Potassium

An essential mineral studied for blood pressure, requiring caution with kidney disease or certain medications.

Evidence category: Reference only. This describes the source category, not approval or certainty.

Regulatory statement in source: Not separately recorded; do not infer approval from the evidence category.

Potassium is an essential mineral and electrolyte required for nerve signaling, muscle contraction, and fluid balance, and it is naturally abundant in fruits, vegetables, legumes, and dairy. It is classified as an essential nutrient with a well-established adequate intake, and decades of research have examined its role in blood pressure regulation and cardiovascular health. Most healthy adults meet their needs through diet alone, and supplementation is generally reserved for documented deficiency under medical supervision.

Benefits reported in the imported source

• Supports normal nerve and muscle function as an essential electrolyte the body cannot do without
• Blood pressure reductions have been observed in supplementation trials in hypertensive populations
• Adequate dietary intake is associated with lower stroke risk in large observational cohorts

Risks and limits

• Impaired kidney function or medications that reduce potassium excretion, such as ACE inhibitors, ARBs, or potassium-sparing diuretics, sharply raise the danger of hyperkalemia from added potassium
• Severe hyperkalemia can cause muscle weakness, paralysis, and life-threatening cardiac arrhythmias
• No tolerable upper intake level has been set for potassium because the harm reported in case studies came from rapid, concentrated exposure rather than food-level intake, which argues for caution rather than reassurance with concentrated supplements

Source bottom line: Potassium is essential and well studied for cardiovascular health, but it is also a rare case where supplementation carries real danger for people with kidney disease or interacting medications, making it a nutrient best supplemented only under clinical monitoring of blood levels.
