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.
