Magnesium Linked to Lower Blood Pressure as Coverage Underscores Safe Intake and Overdose Risks

Overview

• New reporting cites studies showing daily doses around 300–600 mg can lower both systolic and diastolic blood pressure, with calls for monitoring magnesium status during therapy.
• The DGE advises roughly 350 mg per day for men and 300 mg for women, yet many supplements start at 300 mg, making it easy to overshoot when diet is included.
• Media cite conflicting BfR advice on supplemental upper limits, with one outlet quoting 200 mg per day and another 250 mg, adding to consumer confusion.
• Diarrhea is the most common early sign of excessive intake, while severe effects are rare and typically associated with very high intakes around 2,500 mg daily.
• People with impaired kidney function are at elevated risk of magnesium accumulation and are advised to use supplements only under medical supervision.
