That is what I found when I did research a couple years ago before buying some magnesium supplements. However, at that time, I did not know about the supplement in this post.

Citrate for muscle relaxation/recovery, also used to help with constipation.
Threonate crosses blood/brain barrier, able to be absorbed by neural tissue. Used for sleep/neural performance.
