This definitely saved my sleep! I am pregnant with an extreme case of restless leg syndrome that was worst while lying in bed or when resting. I heard magnesium could help with that and it definitely helped me. I went from tossing and turning for four hours with no relief to sleeping through the night just fine. I have absolutely no trouble falling asleep at night. I take one pill in the morning and two before bed. I do not take them with my other vitamins as sometimes magnesium interferes with the absorption of other vitamins. I usually wait two hours between regular vitamins and the magnesium. I definitely recommend this to anyone suffering from restless leg syndrome. Cheers!!

My chemist friend tells me that Magnesium L Threonate is the only magnesium that crosses the blood brain barrier because it is joined with a enzyme. What I notice is that if I am in bed with the light off, it also provides for me a small shift that allows me to drop that last bit into sleep. It also doesn't create diarrhea as so many magnesiums can.

This product definitely makes me more alert -- like caffeine without the buzz. If I take it too late in the day, it keeps me awake at night. But then I started to wonder why most forms of magnesium don't cross the blood-brain barrier. If my brain needs magnesium, it will let it in. I don't think I want to trick my brain into admitting a mineral it normally excludes. I'm going to save the rest of my bottle for times when I absolutely have to be alert and caffeine isn't doing the job. Or until research is published that shows it's safe.

Works great I felt the difference the first morning after taking it. Feels like I have been in a fog all my life and now that is gone.

Its recent batch "A 243187" has a distinct offensive hydrocarbon chemical smell. Obviously the product is contaminated with solvents that would be wise to avoid.

I ordered 2 bottles from Swanson and the smell is so toxic irritates my nostrils.
