Formula overview
Magnesium is the mineral most of us assume we are getting and most of us are not. Quietstone gives you 200 mg of elemental magnesium in every capsule, built on Albion® magnesium bisglycinate chelate, a form where magnesium is bound to the amino acid glycine.
We tell you exactly how it is made. The 200 mg comes from bisglycinate chelate plus a small amount of magnesium oxide as a buffer, which is how a capsule can carry a full dose in one piece. Nothing is hidden behind a front-label word.
The capsule is plant cellulose, the rest is a short list of vegetable-source flow aids, and every lot is built to be tested before it reaches you.
What it does
Supports a calm, relaxed state*
Magnesium takes part in how nerves signal and how muscles let go. Getting enough of it is one of the simplest ways to support a calm evening routine.
Supports healthy muscle function*
Muscles contract with calcium and relax with magnesium. A steady supply helps muscles do both jobs normally.
Plant-based capsule, plainly labeled
A vegetable-cellulose capsule, no gelatin, and an honest label that tells you the formula is buffered with magnesium oxide.
How it works
Magnesium is a cofactor in hundreds of enzyme reactions, including those that govern nerve signaling, muscle relaxation and cellular energy. Chelated magnesium, where the mineral is bound to amino acids such as glycine, is a widely used format for supplements because the bound form is designed to travel with the amino acid. In Quietstone the chelate is paired with magnesium oxide, which raises the elemental magnesium per capsule.
Who it's for
Adults who want to close a magnesium gap, who train hard or sit under daily stress, or who want a simple evening mineral that is vegan and clearly labeled.

Read our planned standardsQuestions, answered
Is Quietstone pure magnesium glycinate?
Not entirely, and we say so. The formula is buffered: it combines magnesium bisglycinate chelate (Albion®) with magnesium oxide. That is how 200 mg of elemental magnesium fits in one capsule.
Will it make me drowsy?
No. Magnesium is a mineral, not a sedative. Many people simply prefer to take it in the evening.
Can I take it with food?
Yes. The suggested use is with meals, which also helps limit stomach upset.
Is it vegan?
Yes. The capsule is hydroxypropyl methylcellulose (plant cellulose) and every other ingredient is plant-source or mineral.
