Magnesium & Blood Pressure: How Does Magnesium Affect Blood Pressure? - Thomas DeLauer

Every day, we're scared into thinking that we can't do anything about our high blood pressure. Day in and day out I hear from people that are struggling with high blood pressure and their doctors are telling them that if they don't change their diet, if they don't change their exercise routine or if they don't change their lifestyle, they're going to end up dying because of their high blood pressure. Now, I'm not saying that those doctors are wrong, but what I am saying is we need to look at the bigger picture. We need to look at some other things outside of just the good old fashioned changing your diet and adding more exercise.

All right, so what I want to talk about in this video is how magnesium actually affects blood pressure. You see, as we're progressing through various forms of research, we're starting to find that there's a lot more to blood pressure that what we thought. We used to just think it was kind of a sodium thing, how our bodies were sensitive to sodium and how that would ultimately affect the overall water retention, how it would overall effect just how our constricting blood vessels, et cetera, et cetera. But as we go forward we're learning that minerals really do play a bigger role outside of just sodium. So when it comes down to magnesium, it's pretty powerful and I want to reference this entire video surrounding one particular meta-analysis study. Now, for those of you that have watched my videos before, you know that a meta-analysis is a study that takes a look at a bunch of different studies aggregated together.

So in this particular one, we took a look at a study that was published in the American Journal of Hypertension, this is a journal that specializes in blood pressure. So blood pressure research looking at all kinds of different studies and this one particular meta-analysis took a look at 34 different studies that had a total of 2,000 patients. So this is a very big study. These are the kind of studies you want to look at to give you a very solid, definitive answer. So, the studies that they looked at were what are called randomized placebo studies, which means the subjects did not know whether they were receiving a placebo or if they were receiving magnesium. Now, since we looked at a lot of different studies, it ranged anywhere from 248 milligrams of magnesium that were given to the subjects all the way up to 960 milligrams of magnesium that were given to the subjects. What they did is they looked at all these studies, and some of these ranged from three weeks all the way up to eight months.

They took a look at where the average balance would change in terms of someone's blood pressure or where the average change would just generally occur and what they found is after about three months on average, if you consumed approximately 368 milligrams of magnesium, you were expected to see approximately a two millimeter of mercury decrease in your systolic and a 1.8 millimeter mercury decrease in your diastolic blood pressure. And then researchers later on, after digging into the research even more found that, really, only after a month, you would see a big difference. That's pretty darn powerful and it may not sound like a whole lot when you're looking at the big picture, but when it's just one simple factor that you're changing, that is very powerful. This is not changing the diet and not changing exercise.
