Melatonin is a hormone. It tells your body what time it is, which makes it a reasonable tool for time-zone shifts and schedule changes. That is what it was studied for.
HAVN1 takes a different route. Magnesium is a mineral your body already uses in hundreds of everyday processes, including the ones that help your nervous system downshift at the end of the day.*
Because there is nothing in HAVN1 designed to sedate you, there is nothing to sleep off. No hormone, no morning fog ingredients. Just one well-studied mineral in a form chosen for absorption.*
Each 3-capsule serving carries 275 mg of elemental magnesium from 2,500 mg of magnesium bisglycinate chelate (magnesium bound to glycine, the calming amino acid). That is the entire active formula; the only other ingredients are the hypromellose capsule, magnesium stearate, silicon dioxide, and rice flour.
Vegan-friendly, gluten-free, and non-GMO. No melatonin, no proprietary blends, no synthetic colors, nothing habit-forming.
The dose sits inside the 200–400 mg range used across clinical sleep research. The full study summaries, including their limits, are further down this page.
Every batch is made in a US, FDA-registered, cGMP facility and third-party tested, with a certificate of analysis available on request.
Take 3 capsules 60–90 minutes before bed, at a consistent time. Consistency is the mechanism. Magnesium works with repletion and rhythm, not on demand.
A two-minute nightcap with nothing in it to sleep off. Mix it when the kitchen closes.
Supports restful sleep, calm, and relaxation by restoring a mineral most modern diets run short of.* No sedation, no hormone signaling, no next-morning fog ingredients. HAVN1 supports the conditions your body uses to wind down on its own.*

Made and tested so the label is provable, not aspirational:
The research
PMID 40918053 · n=155 · 250 mg/day
Adults taking magnesium bisglycinate for four weeks reported improved insomnia-severity scores versus placebo. The closest published trial to HAVN1's form and dose.
Mah & Pitre · PMID 33865376
Pooled the existing trials and found modest improvements in measures of sleep, while rating the overall evidence quality as low and calling for better trials. We cite it because that is what the evidence actually says.
These studies examined magnesium in various forms, not HAVN1 itself. We summarize them honestly, including their limits.
The test that matters is how the next morning feels.

Comparison reflects common product formats in each category, not any specific brand. Magnesium oxide is poorly absorbed relative to chelated forms and is commonly used as a laxative.

Most clinical sleep studies on magnesium ran two to four weeks. Set your expectations there. Take it nightly at a consistent time, since magnesium works with repletion and rhythm, not on demand. If night 30 arrives and it has not earned its place, the guarantee covers you.
No, and it is not supposed to. HAVN1 is not a sedative. There is nothing in it designed to force sleep. It supports the conditions your body uses to wind down on its own.* If you want something that hits like a sleeping pill, this is not that, on purpose.
Melatonin is a hormone that signals what time it is. It is useful for jet lag and shift changes, which is what it was studied for. We chose a mineral your body already runs on instead, so there is no hormone to take nightly and nothing sedating to sleep off the next morning.
The form decides how magnesium is absorbed and tolerated. Oxide is cheap and poorly absorbed. It is commonly used as a laxative. Citrate absorbs better but can still be rough on digestion at sleep-support doses. Bisglycinate chelates the mineral to glycine, a calming amino acid, making it one of the gentler, better-absorbed forms. That is why it is the only form we use.
A fresh bottle ships every 30 nights at $24.99, 17% off the one-time price, locked in for as long as you keep it. Pause, skip, or cancel anytime from your account. No minimum commitment, no hoops, no retention scripts.
