Magnesium and Blood Pressure Meds: Timing Matters for Safe Use
Magnesium can mildly lower blood pressure, especially if deficient, but it is not a substitute for prescribed meds. When taken with BP medications, magnesium can enhance their effects and sometimes cause blood pressure to drop too low; spacing doses by a few hours may help, but follow your clinician's guidance. Magnesium may also affect the absorption of other drugs, and people with kidney disease or on multiple BP meds should be extra cautious and discuss supplementation with their provider.
