— THE SCIENCE
The mineral does the work.
The form decides if it ever arrives.
Magnesium is involved in more than 300 enzyme reactions — including the ones that tell an over-firing nervous system it is safe to power down. The catch isn't whether you take magnesium. It's whether your body can absorb the kind you took.
The mineral behind the calm
Magnesium regulates the messengers that govern rest. It supports healthy GABA activity — the brake pedal of the nervous system — and helps keep cortisol, the stress hormone, in a normal rhythm. When magnesium runs low, that brake gets softer. Sleep gets lighter. The mind gets louder exactly when you need it quiet.
Most people are quietly running low
An estimated 7 in 10 adults take in less magnesium than the daily reference intake. Modern life makes it worse: stress, caffeine, alcohol, intense exercise and even hard water all pull magnesium out of the body faster than most diets replace it. Deficiency rarely announces itself — it just shows up as worse sleep, tighter shoulders and a shorter fuse.
The absorption problem
Here is the part the label never explains. The cheapest, most common form — magnesium oxide — is poorly absorbed. Your body takes up less than 4% of it; the rest passes straight through. A bottle can advertise a big milligram number and still deliver almost nothing usable. The number that matters is not how much magnesium is in the pill, but how much reaches your cells.
Why we chose glycinate
Noru Dusk uses magnesium glycinate — magnesium chelated, or bonded, to the amino acid glycine. That bond protects the mineral through digestion and carries it across the gut wall intact, which is why chelated forms are far gentler on the stomach than oxide or citrate. Glycine is not just a delivery vehicle. It is a calming amino acid in its own right: it supports a lower core body temperature, one of the physical signals that tips the body toward deeper, more restorative sleep.
A dose that actually does something
Each serving delivers 275 mg of elemental magnesium — a clinically meaningful amount, not the trace sprinkle many products use so they can list the ingredient on the label. Paired with glycine, it is dosed at the level the research actually used.
Tested, every single batch
Noru Dusk is made in a GMP-certified facility in the USA and triple lab-tested — for identity, purity and potency — on every production run. Certificates of analysis are available on request. No titanium dioxide, no magnesium stearate, no rice flour, no synthetic colour.
