I also read into vitamins and minerals (while trying to ignore all the snake oil), and I agree with you!

I tried a lot and the ones I keep buying are the same you do - Magnesium, Omega-3, D3+K2 and a B complex. These are not only the ones that most people are likely to be deficient in, these were also the ones that I subjectively felt had a positive effect on me, and either low or deficient levels were confirmed by blood tests. I feel a lot better, too! :)

Regarding the magnesium: I did not know that. How do you make sure the brand and/or it's magnesium is of good quality?

It's curious you say this, I wasn't totally sure, but I sometimes felt like there was a difference in quality, even between the same brand or product of the same form of Magnesium.

The ultimate quality is impossible for me to judge. I just believe them at face value. The problem is that there are different kind of Mg (citrate, carbonate, oxyde) and different ways to write the quantities in the label. It's been a long time since I read it.

One common trick is saying that there is one gram per serving. But in the fine print they say that a serving is not one pill, but two pills. Or three or four.

Another trick was playing with total vs. elemental Mg weight.
