The magnesium built the way the research says.
Magnesium works for migraines. The research is clear on that. It is also clear on when it fails: the wrong form, too small a dose, or stopping before twelve weeks. Most people who tried it and felt nothing hit all three. We built this one so none of them can happen.
What the trials used before they counted a single migraine.
Magnesium is a preventative, not a rescue. It raises the level in your tissue slowly, every day, until your nervous system stops being so easy to set off. Below twelve weeks the research barely finds an effect. Most people quit at three.
So we built the magnesium that fits the research.
Three things the trials got right, and most bottles on the shelf get wrong.
-
The right form. Pure glycinate, no oxide anywhere.
Most shelf magnesium is oxide, and your body absorbs about four percent of it. Many bottles that say glycinate on the front are cut with oxide on the back. Ours has one active ingredient, and it is not that.
-
The right dose. 275mg elemental, printed on the back.
Elemental means the magnesium itself, not the weight of the compound. The front of most bottles says 500. The back says fifty. For migraines, under 200 does nothing. Ours reads 275 on the panel, where you can check it.
-
The right length. Twelve weeks, so it comes as three bottles.
One bottle is four weeks, and four weeks is where people quit. We only sell the full course, because a single bottle sets you up to fail the same way you failed last time.
Why we only sell it as three bottles.
Because we do not want you to take it for three weeks, feel nothing, and decide magnesium does not work for you. That is what happened last time. The research says twelve weeks, so the offer is twelve weeks.
Take it every night for ninety days. If you are not happy at the end of it, you get every penny back. Opened, used, empty. We could not afford to offer that if people did not come back for more.
Most people who start do not want to go without it again.
Made for the women who tried magnesium once, the wrong way, for three weeks, and gave up on it.
What twelve weeks tends to give back.
Magnesium is used in hundreds of processes in your body. These are the ones women with migraines tend to notice, in roughly the order they arrive.
Neck & shoulders
The tightness most migraine sufferers have stopped noticing tends to loosen first. Magnesium is what lets a muscle release.
Sleep
It is what lets your nervous system settle at night. Deeper sleep, usually around week three, and sleep itself is one of the things that holds a migraine off.
The week before your period
The one that was always a guarantee. This is usually where the change shows first, lighter, then shorter, then not at all.
Fewer attacks
Not fewer triggers. A nervous system that is harder to set off, so the same wine and the same bad night pass without one. This takes months, not weeks.
Energy
Every unit of energy your body spends needs magnesium attached to work. The afternoon fog many sufferers live with is part of the same shortage.
A calmer nervous system
The on-edge, twitchy, everything-is-too-loud feeling between attacks is what an over-firing nervous system feels like from the inside.

Elemental magnesium, every night, for twelve weeks.
Elemental means the mineral itself, not the weight of the compound it rides in. Migraine research used 200 to 400mg a day for twelve weeks. Most bottles deliver a fraction of that, hide the number on the back, and run out at four.
What women tell us.
"Twenty two years of migraines, four or five a month, always the week before my period. Month two I had one, and it was a mild one. I am 51 and I have not said that sentence in two decades."
"I had tried magnesium twice and told everyone it did nothing. Turns out I took oxide for three weeks and quit. This time I did the twelve weeks. The tightness in my neck went first, then the migraines started spacing out."
"My husband ordered this after reading something and put it on my side of the counter with a note. I did not believe in anything anymore. Four months later I went to a birthday dinner on a Friday and came home still in my shoes. He was right."
"Ran out for a week over the holidays. By day four the pressure behind my eye was back. That was all the proof I needed. I set the refill up the same night and I have not missed one since."
What happens over the twelve weeks
A level that took years to drop does not come back in a week. This is the order most women notice things, and why the full twelve weeks is the whole game. Tap through the stages.

Questions women ask before ordering.
Almost every woman who says that took the wrong form, at the wrong dose, for too short a time. Three things have to be right at once, and most attempts miss all three.
Time. Magnesium is a preventative, not a rescue. It does not work in a week or two. The trials that worked ran twelve weeks before counting a single migraine, and most people quit at three. The days you feel fine are the ones doing the work, so it has to be every night.
Form. Pharmacy magnesium is mostly oxide, and your body absorbs about four percent of it. Many bottles that say glycinate on the front are cut with oxide on the back. Reversa is pure glycinate with no oxide anywhere.
Dose. The number that matters is elemental magnesium on the back panel. Most bottles deliver under a hundred, and for migraines under two hundred does nothing. Reversa delivers 275mg per serving.
Because one bottle is four weeks, and four weeks is where people quit. The research says twelve, so the offer is twelve. We would rather you did not buy it at all than buy one bottle, feel nothing at week three, and decide magnesium does not work for you. That is what happened last time.
The 90-day plan is the same three bottles at a lower price, delivered every ninety days so you never run out. Skip or cancel any time from your account. No calls.
Usually nothing in the first two weeks. That is normal, and it is where most people quit.
The small things move first, weeks three to six. Sleep gets deeper. Neck and shoulders loosen. The on-edge feeling between attacks eases. Then, around week eight, the week before your period tends to be the first place the migraines themselves change, lighter, then shorter, then not at all. The change in overall frequency comes over months, not weeks.
No. This is not a rescue medication and it is not meant to replace one. Your triptan or your painkiller treats the attack that is happening.
Reversa works on the other side of the problem: how often the attack comes in the first place. Taken every night, it raises the level in your tissue until the same triggers that used to set you off start passing without one.
Especially to you. Every month when estrogen drops before your period, it pulls magnesium down with it. That is why that week has always been the worst one, and why it tends to be the first place women notice a change.
If you are in perimenopause and your migraines have become unpredictable in a way they never were before, the same thing is happening on a less regular schedule.
It is a mineral, not a drug, and it is generally well tolerated alongside migraine medication. Keep everything your neurologist gave you. This does not replace it.
If you take antibiotics or thyroid medication, space them a couple of hours apart. If you take blood pressure medication or diuretics, ask your pharmacist about timing. If you have kidney disease, speak to your own doctor first.
Three capsules with water before bed. Glycinate is the calming form, so it fits the evening, and it means it is in your system overnight, which is when a lot of the settling happens.
The important part is every night, not the exact hour. Mark it on the kitchen calendar if that helps. That calendar is the thing that decides whether this works.
As long as the migraines matter to you. The things that pulled the level down, your cycle, stress, coffee, the attacks themselves, do not stop, so the refill is nightly the way brushing your teeth is nightly.
What most women notice is what happens when they stop. Within a week or two the pressure behind the eye is back and the neck tightens up again. Most people who start do not want to go without it again.

Why three bottles, and not one?
Because the one thing that breaks this is stopping early. One bottle is four weeks, and four weeks is where people quit, right before the level is high enough to notice. The research says twelve weeks, so we only sell twelve weeks. We would not be able to afford a guarantee like that if people did not come back for more. Most who start do not want to go without it again.
And the full 90 days are covered. Take it nightly, and if nothing on your side moves, send one email and it is free. No bottle to return.
