Magnesium glycinate is the form most helpful for sleep. In our yummy magnesium chewable by BrainMD, you get three forms of magnesium ( citrate, malate, glycinate), providing this essential mineral necessary for over 300 different metabolic processes, which greatly enhance brain and body health systemically. 

Is there one that is particularly best for memory? I already take the Brain/Body pills from Dr.Amen.Thanks!

They all are well-absorbed and have benefit for the brain either directly or indirectly, as do magnesium-rich foods such as pumpkin seeds, spinach, chard, sesame seeds, quinoa, cashews, sunflower seeds, and beet greens. It’s important to note that magnesium oxide and magnesium sulfate are poorly absorbed (these aren’t in our magnesium), and magnesium citrate can have a mild laxative effect for those with a tendency towards constipation. Best!

I saw a supplement that has all Magnesium types in it. Is there any advantage to taking  this type of pill? Do we really all lack in all the magnesium types? Thanks so much!

Since different forms are used for different metabolic processes, a combination product can be a good idea. Nutrition surveys done in the U.S. find that magnesium is regularly one of the minerals we are insufficient in due to a variety of factors including less magnesium-rich soil and therefore plants from that soil, higher need (magnesium is used up in high stress, among other conditions common to us), and poor absorption (this decreases with age as well). Best!
