Magnesium is often touted as a way of lowering blood pressure but it seems the jury is still out with the experts. However, a recent meta-analysis reckons it can make a significant difference in lowering both systolic and diastolic blood pressure readings. It struck me then that, if this is the case, the many people who have borderline or mild hypertension could well be in the bracket where raising their magnesium levels would bring it under control enough to enable them to avoid having long-term drugs. That’s worth thinking about.
The results of a meta-analysis were recently published in the European Journal of Clinical Nutrition and you can read the abstract report here:
Note that the level of magnesium used was >370mg, way above the average intake or supplementation levels of the general public. I normally recommend around 300-500mg per day for wellbeing. Without access to the full research, I can’t tell what type of magnesium was used, but I’ll bet it was a cheap unabsorbable form like oxide so you could probably bring bp down with less using a good form like citrate anyway.
One extra point I will make is that levels of magnesium in normal blood tests are, in my opinion, unreliable. Too many times I have seen magnesium levels on test reports brought into me marked as normal and on red blood cell testing, it is too low. Moral of the story: ask for red blood cell testing or get me to do it – it’s included in the Mineral Test but I can also do it as a stand alone mineral or most minerals as red blood cell.
Just as an aside, zinc is highly unreliable too and a very common deficiency – the best for that is white or red blood cell testing.
