Been experimenting with different forms of magnesium for a long time. This one is new to me, taken before bed works well, my dreams are positive so far.

This is the first time I've bought magnesium supplements with this ingredient. My wife has been sleeping very well since taking them, getting about eight hours of sleep every night.
