I sleep better
I just feel like I sleep better. Often though, the ingredient comes out of the pill package and I find the powder all in the inside of the bottle. One time, there was an empty pill.

Invest in you
Have been using other products protein , creatine, and iron.
Wanted to see if there was a difference in the magnesium product had been ordering. Without a doubt, better deep restful sleep feel restored in the AM. You may pay more but your investment is your health.
