About





            

                
Potassium is the primary intracellular cation essential for maintaining cell membrane potential and cardiac rhythm. It promotes sodium excretion, directly counteracting sodium's hypertensive effect. A 2013 Cochrane-grade meta-analysis found increased potassium intake reduced systolic blood pressure by 3.49 mmHg in hypertensive adults. The DASH diet (4,700 mg K/day) reduces systolic BP by 8-14 mmHg.

            

        

        

        
        
        

            

  
How It Works





            

                
Primary intracellular cation essential for cardiac rhythm; promotes sodium excretion by inhibiting renal sodium reabsorption, directly counteracting sodium's hypertensive effect; relaxes vascular smooth muscle via Na+/K+-ATPase activation; suppresses reactive oxygen species in vascular endothelium.
