The 3AM problem

Falling asleep was never the problem. Staying asleep is.

You drift off fine. Then 3:07am arrives and your brain files its report — the email, the invoice, the thing you said in 2014. Wired but exhausted.

So you try melatonin, and you wake up under a wet blanket. You try a cheap magnesium off the shelf, and your stomach makes the decision for you by morning.

The mineral wasn't wrong. The form was.

Why glycinate

Not all magnesium is the same.

Most magnesium supplements use the cheap forms that upset your stomach. Serni doesn't.

01

Glycinate is the calm one

Magnesium bound to glycine, an amino acid that quiets a racing mind. It's the form people reach for when the goal is sleep, not a bowel movement.*

02

Highly absorbable

Chelated magnesium is the form your body actually recognizes and uses — so more of what's on the label ends up where you need it.

03

Gentle on your stomach

No laxative effect like citrate or oxide. Take it nightly without negotiating with your gut.*

Benefits

What 30 nights of Serni feels like.

Fall asleep faster, sleep deeper*

Magnesium supports the nervous system's shift into rest mode, so your body stops idling in fifth gear and the night stays whole.*

  • Supports deeper, less broken sleep*
  • No melatonin, no sedatives

Eases stress & promotes calm*

Glycine is a calming amino acid. Paired with magnesium, it takes the edge off the evening wind-down — the kind of calm you can feel before your head hits the pillow.*

  • Supports a settled, quiet mind*
  • Useful on high-stress days, not just at night*

Gentle on your stomach — no laxative effect*

Citrate and oxide are cheap for a reason. Chelated glycinate absorbs instead of sitting in your gut, so nightly use stays comfortable.*

  • No urgent 6am wake-up calls
  • Take it every night without dread

Non-habit forming — wake up clear, not groggy*

Magnesium is an essential mineral, not a sedative. You're replenishing something your body wants, so mornings feel like mornings again.*

  • No dependency, no tolerance build-up*
  • Clear-headed mornings*
