These tablets are really effective. They do induce a deep and peaceful sleep. I have been struggling with my sleep since years but I never knew I need magnesium glycinate. Due to their high potency i.e., 750 mg I dnt take it daily. I take the tablet after every 3 or 4 days and it is still effective in this way. So, one pack lasts longer. I used magnesium glycinate from another local brand which was too hyped i.e., Herbiotics but that was not effective at all.
