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!

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

Game changer!
I struggled with muscle cramps during the night but after taking Momentous Magtein Magnesium L-Threonate for several weeks, it drastically improved! A year later, I’m still taking this product and I trust this brand. Knowing that the supplement industry isn’t well regulated for safety and sourcing, I reached out to the Momentous Customer Care Team about quality and sourcing and this was their reply: “Thanks so much for reaching out!

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.

Magteen Magnesium for sleep
The first week of use, these helped me fall asleep within 30 minutes. However, the don’t keep me sleeping. I woke up after a few hours consistently. They don’t work as well for falling asleep after a couple of weeks but still help. The bottle has a lot of loose powder in it, which I assume, came from inside the capsules. Capsules are fairly large.

If you have trouble sleeping, this might be the supplement you need!
I was recommended this item from a friend because I was telling her my mother was having hard time sleeping through the night. Quite the surprise to get such a positive feedback from my mother! She usually is skeptical on these types of supplements. It worked very well that my mother recommended it to her friends.
