Every cell in the body relies on this mechanism

In 1957 it was discovered that our cells have a vital membrane protein that uses energy from ATP to move three sodium ions out of the cell and two potassium ions into the cell against their concentration gradient. This is called the sodium potassium pump. This mechanism helps to keep the inside of the cell more negative than the outside, which allows nerve and muscle cells to send electrical signals, which is how our body communicates. It also prevents cells from swelling and bursting by balancing water and ion levels and lastly, it creates a sodium gradient that helps to transport nutrients like glucose cells. Certain organs utilize the sodium pump mechanism more than others like the kidneys that use the sodium gradient to filter waste absorb amino acids and regulate electrolytes. The brain utilizes this mechanism as does the thyroid and even sperm cells. We need 4700 mg of potassium a day and some studies I’ve found suggest that we need between 3000 to 5000 mg of sodium per day. Now, remember table salt is not a good sodium source as it is bleached of all nutrients and minerals. A better source is a sea salt that contains the sodium we need as well as additional minerals.
