The American Heart Association recommends a maximum of 1500 milligrams of sodium per day for optimal blood pressure control. Some experts believe that up to 2300 milligrams per day is acceptable, but the difference in blood pressure between these two levels of sodium intake is only about 2-3 millimeters of mercury. It's important to remember that all forms of salt, including sea salt, table salt, Himalayan salt, and pink salt, can increase blood pressure.
