The best available form. An honest dose. That is the whole idea.
We did not do anything magical. We took the form of magnesium your body absorbs best, put a dose in the bottle that matches what the research actually used, and printed every number on the label. Most brands do not, which is why this one gets ranked first.
Real magnesium per serving. Printed on the back, next to the 2,500mg it comes from.
The studies that found magnesium works used 200 to 400mg of elemental magnesium a day. That is the range this serving sits in. Three capsules, because that is what a real dose of glycinate physically is.
What a real dose does.
Magnesium runs hundreds of processes. At a full dose, these are the ones people notice.
-
Deeper sleep
Magnesium is what lets your nervous system switch off at night. Fall asleep faster, wake less, get more back from the hours you are in bed. Usually the first thing people notice.
-
Muscles that let go
It is the mineral a muscle needs to release after it contracts. Night cramps, twitches and restless legs live here.
-
Steadier energy
Every unit of energy your cells make needs magnesium attached to work. More left in the tank by the afternoon.
-
A calmer baseline
It keeps stress hormones in check and nerves from firing on edge. Less wired, less tight, less on alert for no reason.
-
Heart rhythm and blood vessels
The signal that times every heartbeat runs on it, and vessel walls use it to relax between beats.
Everything on the label, and nothing that is not.
-
Pure magnesium glycinate
The most absorbable form you can buy, gentle on the stomach. No oxide, no buffer, no blend. The only active ingredient.
-
275mg elemental, printed next to the 2,500mg
Both numbers on the panel. The compound and the real magnesium, side by side, so you never have to work out what you are getting.
-
Five ingredients, total
Magnesium glycinate, a plant capsule, rice flour, magnesium stearate, silicon dioxide. That is the entire label. No sugar, no sweeteners, no fillers.
-
Tested by an outside lab, every batch
Elemental content, heavy metals, contaminants. Certificate on request. The 275 on the label is the 275 in the capsule.
-
Refund on an opened bottle, 60 days
Use the whole bottle. If it did not do what we said, one email gets every dollar back. Nothing to ship.
The best form, an honest dose, every number on the label. Nothing else to it.

Others are cheaper per day. They also give you less magnesium. This is the one where the money buys the dose.
Elemental magnesium, every serving.
From 2,500mg of magnesium glycinate. Both numbers are on the back of the bottle, in plain print, so there is no math. Three capsules, because a real dose of glycinate does not fit in one.
From people who switched.
"I had been taking a '400mg' glycinate for two years. Turned it around after reading the comparison. 60mg. Switched, and the night cramps I thought were just age stopped in three weeks."
"Three capsules put me off at first. Then I understood why. My old bottle was one capsule because there was almost nothing in it. Sleeping through the night now."
"I bought it because of the refund. Figured I had nothing to lose. Never used it. Two months in and I am on my third bottle."
"The label says 2,500 and 275 right next to each other. First supplement I have bought where I did not have to guess what I was getting."
What to expect at a real dose
A shortage that took years to build does not refill in a week. Here is the order most people notice things at a full dose. Tap through the stages.

Questions people ask before ordering.
Because glycinate is bulky. Only 11 to 14 percent of magnesium glycinate is magnesium, so 275mg of the real thing is about 2,500mg of material. That is three full capsules. It does not fit in one.
When a bottle promises a real dose of glycinate in one capsule, the number is either the compound weight, or it is oxide, or it is a blend that is mostly oxide. Three capsules is what an honest dose looks like.
Usually little in the first week. That is normal and it is where people quit.
Sleep and cramps tend to move first, in weeks two to four. Then daytime energy and a calmer baseline. Past two months the deeper reserves fill and the early changes stop being occasional. Judge it at eight weeks, not eight days.
The dose, almost always. Turn your old bottle around and find the magnesium line. Most best sellers deliver 56 to 180mg at their labeled serving, below the 200 to 400mg the research used. You were probably taking a fraction of a dose and calling it magnesium.
The form, sometimes. If the ingredients list oxide, buffered, or a complex, most of what you took passed straight through. Reversa is pure glycinate, 275mg elemental, no oxide anywhere on the label.
Magnesium never exists on its own in a capsule. It is always bound to something. In glycinate, it is bound to glycine, and the pair together has a weight. That is the big number on most labels.
The magnesium inside that pair has its own weight. That is the elemental number, and it is the only one that tells you what your body gets. Research uses 200–400mg elemental per day to correct a shortage.
It is a mineral, not a drug. It replaces nothing your doctor gave you. Keep every prescription you have.
If you take antibiotics or thyroid medication, space it a couple of hours apart. If you have kidney disease, speak to your own doctor first.
Three capsules with water. Most people take them in the evening before bed, because glycinate is the calming form and it fits the routine. With your evening meal is fine too.
The important part is every day, not the exact hour.
As long as you want the level to stay up. Your body uses magnesium every day and does not store a surplus, so the refill is daily, the same way eating is.
What most people notice is what happens when they stop. Within a week or two, the sleep and the legs start sliding back.
