If you take magnesium to wind down at night, this delivers. You're getting 300mg of **magnesium** per two-capsule serving, comfortably inside the 100–400mg clinical range — enough to support sleep onset and ease muscle tension. It comes as a glycinate chelate, a form your body absorbs efficiently and one that's gentle on the stomach, so you skip the loose-stool issue magnesium is known for.

The glycinate carrier is a real plus for sleep specifically: glycine itself has a mild calming effect, so it complements what magnesium is doing for relaxation. Beyond sleep, this same 300mg supports muscle function, nerve signaling, and steady energy.

You'll want both capsules to reach the full dose — a single capsule gives you 150mg, half a serving. At 300mg from a supplement you're just under the 350mg upper limit for supplemental magnesium, so you have room to get more from food without overshooting.
