Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Potassium is scientifically validated as a supportive treatment for hypertension (high blood pressure). Numerous large-scale epidemiological and interventional studies have demonstrated that increased dietary potassium intake can help lower blood pressure, particularly in individuals consuming high amounts of sodium or those who are salt-sensitive. The mechanism involves potassium's ability to promote natriuresis (excretion of sodium in urine), relax blood vessel walls, and counteract the hypertensive effects of sodium, thereby reducing vascular resistance and blood pressure levels.

The DASH (Dietary Approaches to Stop Hypertension) studies, which have been widely endorsed by organizations such as the American Heart Association and the World Health Organization, emphasize the role of potassium-rich foods (such as fruits, vegetables, and legumes) in blood pressure control. Randomized controlled trials and meta-analyses have found that increasing potassium intake by around 1.6–2 grams per day can reduce systolic blood pressure by about 4–5 mmHg and diastolic by 2–3 mmHg, especially in people with hypertension.

While potassium supplementation is generally safe for most individuals, caution is warranted in those with kidney disease or those taking medications that affect potassium excretion, due to the risk of hyperkalemia. Overall, the scientific evidence supporting potassium's role in lowering blood pressure is robust, with dietary recommendations strongly advocating for increased potassium intake as part of hypertension management.
