This is a nice idea but unfortunately doesn't translate to significant decreases in blood pressure for most people. 4g of IV magnesium sulphate barely affects the blood pressure.

But I'd still recommend more broccoli for everyone.

Even if it were so (no acute effect, seems unlikely based on, err, anecdata), I've seen claims of it taking up to a year or more to fix a deficiency. It's nt just a nice idea, it actually works. And blood pressure medicine, often diuretics, only worsens magnesium deficiency and thus a magnesium deficiency treated symptomatically with such medicine becomes a chronic hypertensive condition.

This is whey we need to be talking more about nutritional genomics. Magnesium will help for people who have a need for magnesium based on their genetics.

I do not care if a supplement works for "most people", I only care if it works for me.

Everybody has a need for magnesium and MOST people are deficient. Searches will give you a less dramatic percent, but those are measuring serum magnesium, while the important number is red blood cell magnesium.

I don't know if that's enough for everyone, but the other major factors are also evident: excess weight, lack of exercise, chronic high blood sugar, etc.
