Potassium is an essential mineral that plays a vital role in human health. It is required for the proper functioning of several bodily systems and is involved in various physiological processes.
It is important to note that while potassium is an essential mineral, excessive potassium intake can be harmful to individuals with certain medical conditions, such as kidney disease. Therefore, individuals should speak with a healthcare provider to determine their appropriate daily potassium intake based on their individual health needs.
