Biomarkers
Blood Pressure

The evidence shows that increased potassium intake can significantly reduce blood pressure, particularly in hypertensive individuals. However, the research on its effects on muscle fatigue and exercise performance is limited and requires further investigation.

Blood pressure reduction & cardiovascular risk
Adults with and without hypertension; 22 RCTs plus cohort data · Systematic review and meta-analysis of RCTs and cohort studies
High

Increased potassium intake reduced blood pressure in people with hypertension (systolic −3.49 mmHg, diastolic −1.96 mmHg); associated with 24% lower risk of stroke (RR 0.76, 95% CI 0.66–0.89) with no adverse effect on blood lipids or renal function.

Dose:
WHO-commissioned review; evidence base for potassium intake guidelines.
Potassium regulation, muscle fatigue, & exercise performance
Healthy adults and trained athletes · Integrative physiological review
Low

Potassium is actively redistributed between skeletal muscle & plasma during high-intensity exercise; severe reduction of the trans-sarcolemmal K+ gradient contributes to muscle & whole-body fatigue. Maintaining adequate potassium status supports normal neuromuscular function & exercise capacity.

Dose:
Mechanistic review; intervention RCT evidence for potassium supplementation on athletic performance is limited.
