6 Reasons 3AM Drops Is Built for the Other Half of the Night

01 / 06

The Number on the Front Is the Number That Works

A “400 mg” magnesium gummy delivers about 56 mg of the actual mineral. That is the 14% trap: the front of most labels counts the whole molecule, and about 86% of magnesium bisglycinate is glycine. 3AM Drops prints the elemental number on the front: 150 mg per bedtime dose.

The math is done before you buy. No decoder ring, no small print.

02 / 06

There Is Finally a Dose for 3 AM

Everything else in the category is swallowed at bedtime and finished by the second half of the night. The measuring cap here has a half line: 75 mg, measured in the dark into the same cap, for the hour you actually struggle with.

And the label says plainly: never more than two doses in one night.

03 / 06

The Glycine Is a Feature, Not Padding

In a 2007 study, 3 g of glycine before bed improved self-rated sleep and how fast people fell asleep. The carrier in magnesium bisglycinate is that same glycine, and each bedtime dose of 3AM Drops carries just under a gram of it, with vitamin B6 rounding out the formula, a pairing a 2018 study used in adults under heavy stress. Same glycine, smaller dose, and the label says so.

Most brands hide the glycine. This one weighs it.

04 / 06

The Whole Night Stays Under the Ceiling

The daily ceiling for supplemental magnesium set by the National Institutes of Health is 350 mg. A full line plus a half line adds up to 225 mg, under it with room to spare.

Liquid, measured, and gone in a sip. No horse pills, no morning fog.

A Ritual You Can Do in the Dark

Powders need a glass and a light on. Capsules need counting. This needs a thumb: fill the cap to the line at bedtime, to the half line if the night breaks. The drawer of things that “did not work” is usually a drawer of rituals too clumsy to keep.

No prep, no guessing, nothing to measure twice.

The Proof Is a Document, Not a Slogan

Every lot goes to an independent lab for an ICP assay: the elemental magnesium measured, plus heavy metals and microbiology, published with its lot number. Lot one is pending, and this space stays empty until the document lands.

“Lab tested” is a badge anyone can print. A certificate with your lot’s number on it is a receipt.

On a daily prescription?

Magnesium can interfere with how some prescriptions absorb, thyroid medication and some antibiotics among them. Usually that means spacing the doses hours apart. Bring the panel to whoever wrote your prescription: 150 mg elemental magnesium, plus glycine and vitamin B6.

Tried glycinate and it did nothing?

Check the panel for the word “elemental.” A “400 mg” capsule usually carries about 56 mg, taken once, hours before the hour that breaks your night. This changes the amount and the timing. If it still is not your answer, that is what the 90 nights are for.

Why a second dose?

Because the wake-up happens around six hours after bedtime, and what you swallow at 9 PM is not at its peak at 3am; melatonin, for example, has a published half-life of about 45 minutes. The industry’s answer is a second layer inside the tablet, a guess made six hours early.

Ours is a second dose you take only if the night asks for it, measured on the half line, with the whole night staying under the 350 mg supplemental limit.

What’s in every dose

150 mg of elemental magnesium, from about 1,060 mg of magnesium bisglycinate. About 0.9 g of glycine, from the bisglycinate chelate. Vitamin B6, with the exact amount printed on the Supplement Facts panel. Natural, sugar-free sweetener and flavor. No magnesium oxide, no “buffered” magnesium, no proprietary blend, no added sugar.

How to take it

One full cap line (10 mL) at bedtime, straight or in a splash of water. If your eyes snap open at 3:15, wide awake, take the half line: 75 mg, a teaspoon’s worth.

Never more than one full plus one half dose in a night: 225 mg, under the 350 mg supplemental limit. Keep it two hours apart from osteoporosis medication or antibiotics. If you have kidney disease, talk to your doctor first.

The 90-Night Trial

Ninety nights from the day it arrives. If it did not work, if it upset your stomach, if you hated the taste, if you changed your mind: one email, full refund, and the bottle stays with you. No form, no return shipping, no questions about how much is left.

One night, two halves

The 9 PM Bet

Every sleep aid you have ever tried was a bet placed at 9 PM, six hours before the problem happens.

Melatonin peaks in about an hour and has a half-life of about 45 minutes. By 2am, less than 2% of the peak is left.

The night has two halves

Their answer is a guess. Ours is a dose.

The second dose

One cap. Two lines.

150 mg

The full line at bedtime. Elemental magnesium, printed on the front.

75 mg

Never more than two doses in one night: 225 mg, under the 350 mg limit.

Instead of a review wall

The Receipts

Reviews will appear here when they are real. Until then, the evidence the formula is built on:

250 mg

A 2025 placebo-controlled study of 155 adults reporting poor sleep: elemental magnesium improved sleep-quality scores. Modestly, and measurably. Our bedtime line is 150 mg, and we will not pretend otherwise.

3 g

Glycine before bed in a 2007 study: better self-rated sleep and faster sleep onset. The carrier in bisglycinate is the same molecule.

350 mg

The daily ceiling for supplemental magnesium set by the National Institutes of Health. A full night here is 225 mg: both doses, still under it.

Why it exists

“Our mothers had not failed magnesium. They had been sold a number that was not the number.”

Our mothers are the reason this exists. Two of them, in two different cities in Brazil, both waking up somewhere around three in the morning, both for years. Both had been told the same things: less coffee, more yoga, try magnesium. They had both tried magnesium. There was a bottle in each drawer.

The night we finally turned those bottles around and read the panels, neither printed the word “elemental.” One was delivering about 56 mg a night. The other did not print enough for us to work it out at all.

So we went and made the bottle we wanted them to have: the real figure on the front, and a second measured dose for the hour that was actually waking them up. It tastes like the sea, and we decided we would rather explain that than dilute it.

Check your bottle

The same math, applied to the shelf.

Go get the bottle in your drawer. Turn it around, find the Supplement Facts panel, and look for the word “elemental.” If it is not there, multiply the front number by 0.14. That is what you have been taking.

Before you order

Questions people actually ask

150 mg at bedtime. 75 mg at 3am, if the night asks. Declared on the front.

Start My 90-Night Trial

Charged once. Nothing renews.

I have tried magnesium glycinate for the 3 AM wake-ups. It did nothing.

Check what you took. If the panel did not print the word “elemental,” a “400 mg” capsule was carrying about 56 mg, taken once, six hours before the hour that breaks your night. Two things were wrong at the same time: the amount, and the timing.

This changes both. It may still not be your answer, and that is what the 90 nights are for.

What does it taste like?

Like the ocean. Not the pretty part: the mineral part, the way the air tastes on a beach before the sun comes up. It is saline and slightly bitter, and it is over in one swallow.

Here is why we did not fix it. Bisglycinate, the gentle form, tops out near 15 mg per milliliter, and 150 mg of it in a 10 mL dose sits right at that ceiling. That much real mineral in that little liquid tastes like mineral. The pleasant ones taste pleasant because there is not much in them. We would rather you taste the dose than taste the flavoring. Keep a glass of water on the nightstand and chase it.

I have read that magnesium glycinate gives some people vivid dreams or nightmares.

It is a real thing some people report, and we are not going to pretend otherwise. Nobody can tell you in advance whether you are one of them. If it happens to you, that is exactly the kind of night the 90 nights covers: write in, keep the bottle, get your money back.

Sounds too good to be true for a $45 bottle.

Nothing here is too good. The claim is small on purpose: a declared dose, a second measured dose for the hour you actually wake, and a certificate you can check against your own lot number. No 30-day transformation, no clinical trial of our own, no doctor count. Small claims are the only kind you can keep.

I am used to pills. Will I forget a liquid dose?

The bottle is designed to live on the nightstand, not in the cabinet, because the second dose has to be reachable in the dark. For the first two weeks, most people put it beside whatever they already touch at bedtime: the lamp, the phone, the book.

Will it upset my stomach?

Bisglycinate is the form chosen specifically because it is gentler than citrate and oxide, which are the two that send people running. At 150 mg it sits well under the amounts that usually cause trouble. If your stomach still disagrees, the 90 nights covers it.

Will it make me get up to use the bathroom?

The dose is 10 mL, about two teaspoons. Taken straight or in a small splash, it adds almost nothing to your bladder. If you mix it into a full glass of water at bedtime, the glass is what wakes you, not the magnesium. And if your 3 AM wake-up is your bladder rather than your brain, no supplement fixes that.

I take blood pressure, thyroid, or osteoporosis medication. Is it safe?

Magnesium can interfere with the absorption of several prescriptions, including thyroid medication and some antibiotics, which is usually a matter of spacing the doses hours apart rather than avoiding it. That is a conversation for the person who wrote your prescription. Bring them the panel: 150 mg elemental magnesium, plus glycine and vitamin B6.

What happens if I take both doses every night?

Both doses in one night is 225 mg, which sits under the 350 mg daily ceiling set by the National Institutes of Health in the United States. Never more than two in one night, and that limit is printed on the bottle rather than buried in a page like this one.

What does the 90-Night Trial actually cover?

Ninety nights from the day it arrives. If it did not work, if it upset your stomach, if you hated the taste, if you changed your mind: one email, full refund, and the bottle stays with you. No form, no return shipping, no questions about how much is left.
