Two capsules deliver 200mg of elemental **magnesium**, dosed for sleep and muscle relaxation — and because the label counts the magnesium itself rather than the heavier bisglycinate it's bound to, that's a genuine dose, not inflated compound weight. It sits squarely in the 100–400mg supplemental range and covers a little over half the daily target.
The bisglycinate form pairs magnesium with glycine, an amino acid that has its own calming, sleep-supporting role, and it absorbs well while staying easy on the stomach — worth knowing if other magnesium forms have left you with loose stools or cramping.
At 200mg this covers maintenance and everyday calm rather than the higher end of the range; if you're correcting a known deficiency, you may want to combine it with magnesium-rich food or a second serving to push closer to the 310–420mg daily target.
