Meta comment on this thread so forgive me. There are only 40 comments and 3 of them are top level comments stating that taking magnesium supplements cured their health issue. One is anxiety, one is sleep issues, and one is migraines.

These are some of the same claims I hear from the marijuana enthusiasts on Reddit frequently.

I don’t have any points to make about the observation, just noticed it and felt compelled to share.

For anyone taking magnesium supplements that have found it helpful, did you ever get a blood test to look at your magnesium levels and did they say you were deficient based on the reference ranges?

Unfortunately, that is what lots of people do not do. Noticed it recently with Vitamin D where everyone was like: "There is much deficiency, there are no down sites, let's all take it." And I was like: "Sure, there are probably benefits, but for people with actual deficiency. There is a test for that, why don't you do that?" But at that point, it was too late because you can't test for a deficiency once you supplement it.

As much as 90% of the US population may be deficient in vitamin D, so you have a good chance of it. That said, I agree that testing is good, either before or after supplementation.

Ironically, supplementing vitamin D can cause a magnesium deficiency.

I don't disagree with anything you wrote except to say that in Canada & USA the medical system (insurance, etc.) presumes everyone is vitamin D deficient, and so usually testing is not covered unless there is some other pressing concern. So, most people don't get tested.

You can’t overdose magnesium orally if you have healthy kidneys. The worst that can happen is a bit of diarrhea.

I'll add the quiet part: it is off-topic, non-scientific, and all too typical when any discussion edges too close to health and exercise.

Medicine solves some medical problems, if you're taking the right medicine. (I think this is all a layperson can take away from the observation.)

Oh, an observation
