Methodology
Meta-analysis of 33 randomized controlled trials of oral potassium supplementation on blood pressure
Key Findings
Potassium supplementation reduced systolic blood pressure by 3.11 mmHg and diastolic by 1.97 mmHg, with larger effects in those with high sodium intake
Conclusions
Oral potassium lowers blood pressure, especially against a high-sodium background
Limitations
Older trials; heterogeneity by baseline intake and population
Supplements Studied
Potassium supplementation reduced systolic blood pressure by 3.11 mmHg and diastolic by 1.97 mmHg, with larger effects in those with high sodium intake
Outcomes Measured
Potassium supplementation reduced systolic blood pressure by 3.11 mmHg and diastolic by 1.97 mmHg, with larger effects in those with high sodium intake
