It helps

Seems to be helping with sleeping, brain fog, and some nerve pain.

Deeper sleep

I just started this a few days ago, but it seems to be helping me get into a deeper sleep with vivid dreams, so I'll continue using and hopefully will be able to get better sleep!

I didn’t know how much I need this!

I’ve been taking the Magnesium L-Threonate for almost 2 months before bed. It helps me unwind and sleep more soundly and I awaken more alert and energetic. I only wish it was cheaper.

Took the product along with

Took the product along with my Protocol for Life Magnesium Glycinate before I went to sleep. Had the same reaction both nights where I did not feel I slept as deep. I changed my dosing protocol to pre-workout and the change was ideal. Received any brain enhancements through the threonate complex during my workout and had no more negative effects during sleep in terms of how deep I slept.

Brain Fog

[This review was collected as part of a promotion.] I was experiencing a lot of brain fog until I incorporated Magnesium L-Threonate into my vitamin regime. This is a great product.

This is a game changer

[This review was collected as part of a promotion.] I take various supplements but if I run out of this, I can tell a big difference. I sleep better and feel more focused with this MAG LT. I have tried other brands, and they aren't as effective!
