This Natural Factors **magnesium glycinate** delivers a full 200mg of elemental magnesium per capsule, a well-absorbed, gentle form that supports sleep, muscle relaxation, and everyday calm. That 200mg is the actual usable magnesium, not the heavier compound weight some labels list, and it sits squarely in the 100–400mg range research uses for these goals. Take one or two capsules daily and you're getting 200–400mg, covering the full effective supplemental range.
The glycinate form is the reason to reach for this one: magnesium bound to the amino acid glycine absorbs well and stays gentle on your stomach, without the laxative effect that comes with some forms. That makes it well-suited for winding down at night, and since magnesium also supports healthy blood pressure and heart rhythm, and roughly half of adults run low, it doubles as everyday repletion.
