Also, what difference are you feeling?
Differences:
- Sleep is considerably better.
- Haven't had a single muscle cramp even after something like a 30km walk + 60km bike + gym. Otherwise a common occurrence because genetically I have incredibly strong legs and virtually no body fat on my legs.
- Generally I'm less moody and far less likely to (╯°□°)╯︵ ┻━┻ when something stupid happens at work for instance.
- No exhaustion whatsoever.
I also saw a study that said that 95% of children diagnosed with ADHD are magnesium deficient [0]! Another found a "significant decrease of hyperactivity" in children who were given oral magnesium supplements over 6 months [1].
My wrists and hands have felt better, but I've given a lot of attention to them in addition to the supplements, with more upper body workouts (on top of running 10-15 miles a week) and stretches. I'm looking to get more ergonomic tools as well. While I can't say what is and isn't due to the supplements, I don't currently see a reason to stop taking them.

As for your hands, given that you are focusing on upper body workouts maybe one up your protein intake, see if that improves things. Unless you are a vegan, Icelandic yogurt(skyr) is a pretty solid solution(the unflavored kind). In terms of consistency, I'd say it's similar to Philadelphia cheese but almost tasteless. 1 yogurt a day (350g) made a dramatic improvement in my case. Not sure about the US(judging from the fact that you used miles), but you can find those in almost every grocery store in Europe at this point for around a euro.
