Research Question:
To date, there is insufficient evidence on the effect of magnesium supplements on blood pressure. This meta-analysis was therefore carried out to the effect of magnesium supplements on blood pressure rate.
Magnesium supplements reduce blood pressure?
Study Design:
This overview article contained 22 Rcts with 1173 participants, a follow-up duration from 3 to 24 weeks and an average magnesium intake of 410 mg (120-973 mg) per day.
Results and conclusions:
The meta-analysis showed that a magnesium intake the systolic blood pressure (the top number) significantly with 3-4 mmHg and diastolic pressure (underpressure) significantly with 2-3 mmHg did decrease, with a further drop in blood pressure at a magnesium intake of > 370 mg per day.
The researchers concluded that magnesium supplements (410 mg per day) gave a slight drop in blood pressure but it was clinically significant.
