I bought this to help with anxiety & sleep issues not really believing it would do anything but didn't want to take big pharma drugs. Well, I'm so glad I did because it actually works. I took someone else's advice to pop the magnesium before bedtime (I usually do it about 2-3 hours before) and he said "you'll wake up in a better mood and rested" or something like that. I did and was amazed I could finally get some sleep past 3 or 4 hours. It took a few days to work. I've noticed I'm less anxious but I also quit a crappy job so that may also be a benefit of less anxiety. Try this brand--they have good quality supplements. UPDATE 1-21-23: I've been lazy about taking my supplements so I grabbed my bottle to take the very last pill. I woke up this morning feeling rested thanking the universe that I finally seemed to get some sleep, plus I was in a good mood. Then it hit me, I remembered taking my supplement! Promptly bought another bottle 10 minutes ago. Buy it, it worksâ€"at least for me. UPDATE 2-22-23: well, crap…I've been getting major dizziness/Vertigo to the point I cannot walk without falling into something & I was trying to figure out what I'm doing different. So I stopped taking this Magnesium before bed a couple of days & it stopped. Took it last night and guess what? Woke up with the worst Vertigo and went straight to the reviews & saw others complaining about a formula change. Why can't companies just leave their products as is instead of pulling the old “bait n switch”? Now it has mag oxide & a bunch of fillers. Would not recommend. Off to go bubble-wrap myself today until my dizziness subsides
