You're getting 240mg of **Magnesium** per two-capsule serving in the glycinate form — one of the best-absorbed forms available and the one most studied for sleep and relaxation support. That 240mg lands squarely in the middle of the 100–400mg clinical range, so you're covered for a meaningful daily dose without needing to stack extra capsules.
The glycinate form is specifically favored because it's gentle on your stomach compared to oxide or citrate, and glycine itself has calming properties that complement magnesium's role in muscle relaxation and sleep quality. With 60 servings per bottle, you're looking at a two-month supply at the recommended dose.
At 240mg, you're getting a solid maintenance dose, but if you're targeting the higher end of the clinical range for sleep support (closer to 400mg), you'd need to take an extra capsule daily — which cuts the bottle's duration to about 40 days.
