High Blood Pressure
Magnesium deficiency can increase blood pressure in genetically susceptible people, which, in turn, raises the risk of various heart diseases. People who have a positive history of high blood pressure due to hypomagnesemia are also at higher risk for fatal heart diseases.
There are studies and clinical trials going on to find out why low levels of magnesium cause spikes in your BP numbers. However, there is strong evidence that taking magnesium supplements for a long period can help lower blood pressure, especially in young adults with hypertension.
