Potassium is a mineral that is easily absorbed by the digestive tract. This micronutrient is essential for life because of the vital functions it performs in our bodies. Normal nerve conduction, muscle contraction, fluid balance, acid-alkali balance, blood pressure regulation, digestion, protein production, and metabolism require the action of potassium. For example, in metabolism potassium is required for the movement of sugars, amino acids, and other molecules into cells.
Potassium is an electrolyte that takes part in electrical conduction and chemical reactions in opposition to the electrolyte, sodium. In bodily fluids, potassium is the major cation (positively charged ion), while sodium is the major anion (negatively charged ion).
About 98% of the body’s potassium is contained within muscle cells, while (more…)
