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.

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!
