Potassium

Potassium is a mineral that helps maintain your body's fluid balance. Since blood volume expands during pregnancy by up to 50 percent, slighly more sodium, potassium, and chloride are needed to maintain the extra fluid volume. Potassium also helps regulate blood pressure, nerve impulses, and muscle contractions.

How much do I need?
There is no RDA for adults, but a minimum requirement of 2,000 milligrams (mg) during pregnancy has been established; for a nursing mom it's 2,500 mg per day.
