Max-Mag Magnesium L-Threonate
Magtein — the magnesium that supports brain health, focus, and sleep.*
The magnesium that reaches your brain. Most magnesium never crosses the blood-brain barrier. Magnesium L-threonate (Magtein®) does — which is why it’s the form researchers study for cognitive support. Each 3-capsule serving delivers 2000mg of Magtein® (144mg elemental magnesium), plus vitamin D3 and K2. 35 servings per bottle.*
