The best Magnesium on the market
This magnesium supplement is the best I have ever used. My personal trainer recommended it to me and I would purchase through her company. But when she sold out, she provided me with the link she uses and now I order directly. I've been using this product for about a year now and it is a MUST have product for me as it helps give me energy and speeds up my metabolism. Food digests better and I just think my whole body works better. I ran out and was off of them for about two months, because I always got them from my trainer and had no idea I could get them through Amazon until she gave the link. I gained 5 lbs during this time. I take two capsules daily and have zero side effects. Amazing product!

The Best Magnesium for My Brain and Sleep – A Nighttime Essential
I started using Magnesium L-Threonate because I was looking for something that truly supports brain health and improves sleep quality, and I can honestly say it has become an essential part of my routine. This form of magnesium is known for its ability to cross the blood-brain barrier, which means it works directly on the brain, helping with memory, focus, mental clarity, and relaxation. One thing I really like is the capsule size. The capsules are easy to swallow, not big or uncomfortable at all. That makes a huge difference for me when taking supplements daily. I always take it at night, right before going to sleep, and I can feel my body naturally winding down. My sleep feels deeper, I wake up less during the night, and I feel more rested the next day. I also notice an overall sense of calm, as if my mind can relax more easily. If you’re looking for a magnesium supplement that goes beyond the basics and truly supports both brain health and sleep, this is one of the best I’ve ever used. I highly recommend it and will definitely keep it as part of my nightly routine.

Great product, shipping takes too long
I really like this magnesium complex brand it helps me stay asleep all night, when I don’t take it I’ll wake up a couple of times at night. I took a star because it takes forever to arrive.

Need better sleep? Run for these!!!
It used to be so easy for me to wake up to the slightest of noises in the night, and then stay awake for hours because of chatter brain. This Mg has changed all that! I sleep through things that used to wake me up, and if I do inevitably get up, I’ll sleep back in less than five minutes. This is like a miracle to me! My fiancé is taking them too now and he’s sleeping a lot better. I think it’s helping with bowel movement too, but that’s just a bonus. I was more looking for help in the sleep department and got exactly that! Two capsules just before bed and I’m good for the night.
