Sodium makes up half of sodium chloride, which is also known as table salt. Sodium is an electrolyte that plays a role in nerve signaling, muscle contraction, fluid balance and the transferring of nutrients through cell membranes. Our body usually does a good job at maintaining sodium levels in the blood. Excess sodium is peed out and only when you really take in way too much can you develop high blood pressure. When it comes to sodium sources, table salt is the most direct one. Our bodies need around 1500 milligrams per day of sodium to function properly.

But because we get so much sodium through our diets, you actually want to watch out for overdosing and not under dosing. Symptoms of overdosing or dehydration, fatigue and confusion and have left untreated for a long time brain injury can occur. A good way to prevent this is to simply drink more and of course consume less high salt foods.
