Why Magnesium Glycinate Works
The form of magnesium specifically studied for sleep — here's what it does.
Activates Your Relaxation Response
Magnesium glycinate calms the nervous system and promotes GABA activity, your body's natural 'wind down' signal.
Improves Sleep Quality Without Grogginess
Clinical studies show significant improvements in sleep onset, duration, and efficiency without the morning fog of melatonin or prescription aids.
How It Works
Three simple steps to better sleep — starting tonight.
Take 3 Capsules
30 to 60 minutes before bed with a small glass of water. No food required.
Feel the Calm
Within 20 minutes, magnesium glycinate begins activating your relaxation response.
Sleep Deep, Wake Sharp
Fall asleep faster, stay asleep longer, and wake up without grogginess or brain fog.

Frequently Asked Questions
Everything you need to know before trying SleepStack.
Why I Built SleepStack
After two years of trying every sleep supplement on the market, I found the research on magnesium glycinate — and it changed everything. I built SleepStack because I couldn't find a product that matched the science: the right form, the right dose, nothing unnecessary.
