I have struggled with sleep maintenance insomnia for about four years. I would fall asleep fine but wake up at 2-3 AM with a racing mind and lie there for one to two hours before drifting off again. I tried melatonin (gave me vivid nightmares and morning grogginess), magnesium glycinate (helped a little), and prescription trazodone (worked but left me groggy until noon).
I started magnesium L-threonate after hearing Huberman discuss it on his podcast. I take 1,000mg around 4 PM and 1,000mg about 45 minutes before bed, alongside 50mg apigenin and 200mg L-theanine.
Week 1: The first night I noticed nothing different. By night three or four, I realized I had slept through until 5:30 AM without waking. I thought it was a fluke. By night six, it happened again. The sleep was qualitatively different from trazodone sleep — I woke up feeling actually restored rather than sedated into unconsciousness and then dragged back out of it.
Week 2-3: The 3 AM awakenings went from nightly to perhaps twice per week. When I did wake, I fell back asleep within 15-20 minutes instead of lying there for an hour. Dreams became remarkably vivid — full narrative stories with characters and settings. Not unpleasant, just unexpectedly cinematic.
Month 2: Sleep was consistently better. I was averaging 7+ hours of what felt like genuinely restorative sleep for the first time in years. My Oura Ring data showed increased deep sleep percentage from roughly 12% to 18-20%, and REM sleep increased as well.
Month 3: I ran out and did not reorder for about 10 days. By day four without it, the 3 AM awakenings returned. I reordered immediately. That unintentional washout period convinced me more than any study could — the difference between on and off was unmistakable.
No side effects whatsoever. No morning grogginess, no GI issues, no drowsiness during the day. If anything, I feel slightly more alert during the day, which I attribute entirely to sleeping better. This is now a permanent part of my supplement routine.
