Available empirical evidence and facts points to the direction that potassium is a critical component in the human body as a regulator of blood pressure. The above stems from surveys and data recorded over a cross-sectional spectrum of the human population to the effect that areas and regions that take less of potassium have a likelihood of suffering blood pressure-related complications. It is to say that people who take less of potassium have a higher prevalence and prospects of getting hypertension. This logic is true and possible since the ion present in Potassium are unique and provide some functions ...
