I took magnesium glycinate (240 mg) last night. I fell asleep but woke up 2.5 hours later and couldn’t fall back asleep. Normally, I struggle to fall asleep, but once I do, I stay asleep pretty well. I know I can’t judge based on just one night, but what’s everyone’s experience? Do I need a higher dose, or has anyone else had this opposite effect from magnesium?
There might be other things affecting your sleep. Give it a week or two and see how it goes.
I have the same issue with Magnesium Glycinate.
It’s not unusual—if you look into it, some people think it might be linked to a vitamin B1 deficiency.
I’ve noticed slight improvements in sleep since taking One A Day vitamins, which includes B1.

Magnesium helps me fall asleep but not stay asleep.
Don’t focus on it too much. Instead of thinking “this kept me up all night,” give it a solid try (it works for me). Your thoughts are powerful, so try to avoid the negative ones.
I’ve noticed it works best for me when I take it a few hours before bed instead of right before. Give it a solid try because it has worked pretty well for me.
Glycine disrupts my sleep. I had to stop using it. Magnesium oxide is cheap and effective.
I had a similar experience. I’d wake up at 3am and couldn’t fall back asleep. It’s the magnesium, just stop using it.

Relax and let the person who posted this give it a fair try without being influenced by negative comments that could affect its effects. My sleep has definitely improved since I started taking it.

I used it for a while, and magically my sleep got better after I stopped.

You have, but the person who posted this hasn’t. They only took it once. I also experienced that inability to fall asleep; changing the timing of when I take it solved my problem.

How strange; it has the opposite effect for me. It helps me fall asleep more naturally.
Magnesium glycinate does the same to me! The glycine makes my mind race. It might be helpful in the morning if you’re tired.
Magnesium spray really helps me sleep. I just spray it on my legs or wherever.

That’s placebo. Your skin is waterproof; you won’t absorb a significant amount of magnesium through your skin.

Skin absorbs many substances. It’s not waterproof. It’s the same process behind topical steroids.
@Hadi
Topical steroids work at the site applied, not entering your bloodstream to reach your brain. That’s why they’re used for skin issues instead of taking steroids that affect your whole body.
Skin-applied magnesium won’t reach your brain.
Check the study showing that people soaking in Epsom salts don’t have increased serum magnesium levels, except through other routes.
@Ray
Try it for yourself 
@Ray
The skin’s hair follicles help transport magnesium into the body. The dermis below the epidermis has blood vessels that can move substances into your bloodstream.

That’s not true. I’m on a topical estrogen.

Estrogen formulations aren’t the same as over-the-counter magnesium rubs.
@Hadi
I’ll have to give that a try. Thanks!
