Ditch the sleep drugs, improve sleep naturally
High quality supplement. I am meticulous about tracking my sleep and seeking the highest restorative sleep as possible. Been taking for almost a month now and every single night my restorative sleep has increased by a minimum of 15%, usually more. Helps you to fall asleep quicker and overall feel calmer and more focused each morning. Highly recommend.

Game changer for Sleep
Got this on the recommendation of Dr. Andrew Huberman. This stuff has been a game changer for my sleep. Assuming I’m not drinking a gallon of water before bed, this has nearly eliminated all wakeups in the middle of the night. I’ve been on this now for several months and have truly noticed the difference both in sleep and cognitive function. Check it out.

Great product
I just started taking this and so far it seems to be working. It says to take 3, but I took 2, because I wasn’t sure how it would affect me. I ended up taking only 1 at night and it works well. No side effects, so far. Will definitely keep using.

Do the job but expensive
Really help me sleep and go back to sleep if awaken in night. But they are pricy.

Fantastic supplement
It was suggested by my doctor that I start taking magnesium supplements, specifically l-threonate. It has been incredibly helpful with getting proper sleep and reducing night time waking.

Would not recommend
I got these because I ran out of the magnesium glycinate I was taking from a different brand, and found this one was more effective because more is absorbed since it crosses the blood-brain barrier. First of all, the first thing I noticed is there’s an insane amount of powder in the bottle mixed in with the pills. I have purchased many supplements and have not seen this before. It’s to the extent that if you tip the bottle over to get pills out, you will make a mess. So I usually just reached in to grab the pills and my fingers came out covered in powder.I have pretty regular menstrual cycles and this is the only thing I did different in the weeks leading up to the period after I started taking it- it delayed my period by over a week. There’s a lot of people on Reddit saying it happened to them too but it hasn’t been studied enough (shocker I know) so it is not a medically confirmed side effect. I had no issue with the glycinate pills affecting my cycle whatsoever. I gave these to my husband and purchased glycinate again for me (I’ve already had my next period on time btw), and he said the 3 times he has tried taking them he constantly wakes up throughout the night. He has tried taking the glycinate, these, and nothing at all, and the nights he takes these pills are the only time he experiences this terrible sleep.I would personally go with a different brand and it’s pretty unfortunate that Amazon doesn’t allow for returns for supplements because this bottle was pretty pricey and we just wasted that money
