The milligram on the front is usually not the milligram that matters
500 mg on the label.
Far less in the capsule.
Oxide.
A number that isn't the number.
A big figure on the front is often the weight of the whole compound, not the magnesium inside it. The figure worth comparing is elemental magnesium —
Form first. Then the number.
Three decisions went into this bottle, and two of them were about what to leave out.
Glycinate, chelated to glycine Gentle, well-absorbed magnesium for evening use
No oxide, at any dose Pure glycinate with no cheap magnesium oxide
Elemental magnesium, stated plainly The real magnesium amount, clearly shown
What the first month actually looks like
Magnesium isn't a sedative and it doesn't work like one.
Knowing that in advance is the difference between giving it a fair run and quitting on night three.
Nights 1–3
Probably nothing. It won't knock you out, and it isn't supposed to.
Week 1
Some people notice they settle a little faster. Plenty notice nothing yet.
Weeks 2–3
If it suits you, it shows up as less restlessness — not as a switch being flipped.
Week 4
Bottle's done. Now you have something real to judge it on.
If you wake up groggy, drop to two capsules or take them earlier in the evening. Persistent sleep problems are a conversation for a healthcare professional, not something a supplement should be asked to fix.
Built for consistency
Put it where you already stop for the night.
Next to the kettle, by the toothbrush, wherever the evening actually slows down.
Three capsules, no timing window, no ritual to build.

FAQs
Will it knock me out?
No, and you should be wary of any magnesium that promises it will. Magnesium isn't a sedative. What people describe is settling more easily rather than being switched off.
Will I feel groggy the next morning?
Most people don't. If it does happen, take two capsules instead of three or take them earlier in the evening.
What's the difference between glycinate, citrate and oxide?
Oxide is the cheapest and most poorly absorbed. Citrate absorbs better but can have a laxative effect at higher doses. Glycinate is bound to glycine and is generally gentler on the stomach.
What does “elemental magnesium” actually mean?
It's the amount of magnesium itself rather than the weight of the whole compound. Elemental magnesium is the figure that lets you compare two bottles.
Can I take it with melatonin?
There's no known interaction, and plenty of people take both.
