Electrolytes Associated With Improvements in Blood Pressure
Electrolytes are minerals in the body that have an electric
charge, such as sodium, potassium, calcium, and magnesium. They help balance
the amount of water in the body. A new study suggests that lowering sodium and
increasing potassium and magnesium intake may help improve blood pressure.
The researchers included 32 analyses in their review. The
analyses looked at the effect of sodium, potassium, calcium, and magnesium on
blood pressure. In the studies on sodium, sodium intake was reduced from 1.2 to
5.7 g/day and salt reduction was 2 to 9.6 g/day. In the magnesium studies,
supplements were between 6 and 250 mmol/day. For the calcium studies, calcium
intake was between 0.5 and 2 g/day. Intake in the magnesium studies ranged from
Lowering sodium intake resulted in an average 6 mmHg reduction in
systolic blood pressure and an average of 3 mmHg in diastolic blood pressure.
Increasing potassium resulted in an average 7 mmHg reduction in systolic blood
pressure and an average 4 mmHg reduction in diastolic blood pressure.
Sufficient calcium intake was found to lower the risk of
gestational hypertension. Increasing magnesium intake resulted in an average 9
mmHg in systolic blood pressure and an average 5 mmHg in diastolic blood
The study was conducted by researchers from The Medical
University Vienna. It was published on June 17, 2019 in the journal Nutrients.
