Potassium

Blood pressure and vascular health markers is closer to a research marker, so it should be read separately from a directly felt benefit.

Key precautions
No combination caution signal is clear enough to show right now. This does not guarantee safety.
1 combo signals and 0 added-signal combos shown below.
Standalone side effects, combination cautions, and positive combos are separated below.

Combinations studied together

The group showed a positive signal, but individual contributions are hard to isolate. Not a stack recommendation.

+MagnesiumA combination of Potassium and Magnesium Citrate significantly reduced urinary 8-isoprostane levels compared to placebo (p < 0.001), whereas Potassium Chloride and Potassium Citrate alone had no effect.

Evidence summaries

Paper IDs and full lists are private. Only study types and summaries are shown.

Key Evidence #1
Public scholarly dataCitation signal: 182
observational

An adequate intake of potassium is desirable to achieve a lower BP level but excessive potassium supplementation should be avoided, particularly in specific subgroups, according to the findings of a meta‐analysis.

Key Evidence #2
Public scholarly dataCitation signal: 117
observational

Average sodium intake in all age groups across China is approximately double the recommended maximum limits, and potassium intake is less than half that recommended.

Key Evidence #3
Public scholarly dataCitation signal: 91
observational

Higher sodium intake and higher dietary sodium-to-potassium ratio were associated with a higher risk of stroke and can be considered as a supplementary approach in parallel with the decrease in sodium intake in order to decrease stroke risk.

meta-analysis

The findings indicated that potassium supplementation is a safe medication with no important adverse effects that has a modest but significant impact BP and may be recommended as an adjuvant antihypertensive agent for patients with essential hypertension.

Public scholarly dataCitation signal: 61
observational

The reduced-sodium added-potassium salt led to a substantial reduction in systolic BP in hypertensive patients, supporting salt substitution as an effective, low-cost intervention for BP lowering in rural India.

Public scholarly dataCitation signal: 53
observational

Global mean potassium intake falls below current guideline recommended intake level of  > 3.5 g/day, with only 14% (95% CI 11–17%) of the global population achieving guideline-target mean intake.
