Give it a chance! Love it!
I really am liking this product. I take it and within 30 minutes I’m settling down, and within an hour I’m falling asleep. Gently. I wake up on the night to use the restroom. Thinking I’m wide away. Nope. Lay back down. Just close my eyes and next thing I know it’s time to get up for the day. I’m still on the first bottle. This worked for me from day 1. I would recommend being patient with this. Take it daily an hour if you can before bed. Make sure to wind down for bed. Get comfy. Also work on relaxing your mind as best you can. You will think you are wide awake, but you aren’t. There are still times I can’t sleep quickly due to caffeine intake or heavy exercise etc. but this product works still on deep quality sleep once I fall asleep. Love this product

Works for me!
I've been battling sleep disruption for years due to perimenopause. I heard about this product on a Stacy Sims' podcast. This is the best OTC product I've ever taken for sleep. I take diphenhydramine hydrachloride (brand names are Simply Sleep & Benadryl - it's a sedating antihistamine) when I travel because it's cheap and easy to find, but prefer natural methods when I'm at home. This is mineral based, and I get good and sleepy within an hour and doze blissfully at night. I like the clean ingredients, and yes it's pricey, but worth it for a good night's sleep with no morning brain fog!

Nothing Works for Sleep Except This
I have ADHD and cortisol dysregulation. I have a next to impossible time getting to sleep without taking something that makes me groggy or feel off the next morning (i.e. NyQuil). I also hate taking NSAIDs every day, but ibuprofen also really helps. I have started taking this magnesium religiously before bed. I don’t sleep perfectly, but it’s the only product that consistently relaxes my body and helps me get to sleep. I accidentally took Momentous’s Magnesium Malate a few nights ago thinking it was this and I slept horribly. The magnesium Malate is helpful not in a larger dose at bedtime. All the years of advice to take Magesium Glycinate before bed and it almost never did anything unless it was stacked with 4 other supplements. I will continue to purchase Momentous’s Magnesium L-Threonate. I am now a believer.

Relaxing and calming
I originally started using this for my migraines, but the added benefit was the restful sleep. It makes me get pretty sleepy and relaxed, I compare it to melatonin. I am a dietitian and I recommend it to my clients who are looking for magnesium.

Good
Seems to work well. Only problem is that some of the capsules are not completely full and there’s a lot of powder at the bottom of the bottle

Restful sleep, easy on stomach
I've been using Magnesium Magnite and have had a really positive experience. I fall asleep more easily and wake up feeling more rested. Also, appears to be gentle on my stomach (only been 2 weeks), and I find the capsules really easy to swallow.

Best non-drug sleep aid.
This is a great product if you have a hard time falling asleep. After taking it for a while, I did a test where I didn’t take it for a few days, because I personally believed that the effect was maybe placebo. I had a noticeably difficult time falling asleep on the days that I did not take it, and opposite feeling on the days that I did. I will note, this doesn’t keep you asleep, I still wake up in the middle of the night sometimes, but most of the time I am able to get back to sleep. This is the best thing I have tried for a sleep aid aside from melatonin or Benadryl, but obviously this is much preferable.
