What is Sodium?
Sodium is an important electrolyte that your body needs to maintain blood pressure and fluid volume. It also plays a role in nerve and muscle function. Salt is the most common source of sodium, but it is also present in other food sources like milk, celery, sauces such as soy sauce, seasonings, and processed food.
Healthy adults should limit sodium intake to 2,300 mg per day while those with high blood pressure should limit it to 1,500 mg per day.
Normal Sodium range: (May vary among various labs) 135 – 148 meq/L
