Synopsis

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

Potassium is scientifically validated as an essential mineral for heart (cardiovascular) health. Numerous well-designed studies have demonstrated that potassium plays a critical role in maintaining normal heart function, particularly by helping to regulate blood pressure and supporting proper electrical signaling in the heart muscle. Potassium acts as a vital electrolyte, counterbalancing the effects of sodium in the body and assisting in the maintenance of normal fluid balance. Adequate potassium intake is associated with a lower risk of hypertension (high blood pressure), which is a major risk factor for heart disease and stroke. Clinical guidelines from health authorities such as the American Heart Association and the World Health Organization recommend sufficient dietary potassium as part of a heart-healthy diet. Additionally, potassium directly influences cardiac muscle contraction. Low potassium levels (hypokalemia) can cause arrhythmias (abnormal heart rhythms) and, if severe, can be life-threatening. This is why potassium supplementation or increased dietary intake is often recommended in certain heart conditions or when patients are taking medications (like diuretics) that deplete potassium. The scientific consensus is strong: potassium is crucial for cardiovascular health, and its use to support the heart system is well-supported by robust evidence from human studies and clinical practice.
