Description
Life Extension Neuro-Mag uses Magtein, a patented magnesium L-threonate, the form of magnesium chosen when the goal is cognitive support rather than muscle or digestive support. Three vegetarian capsules supply 144 mg of elemental magnesium from 2,000 mg of Magtein, with 30 servings per bottle. No gluten or GMO ingredients are listed.
Magnesium forms are not interchangeable; glycinate, citrate, oxide, and malate are absorbed differently and settle in different tissues. Magtein was developed because most forms do not reach the brain well, and L-threonate appears to do so more efficiently. That makes Neuro-Mag the choice for memory, focus, and mental clarity, and for supporting normal cognitive function through the years. If sleep or cramps are the main concern, glycinate or citrate are usually a better starting point.
- 144 mg elemental magnesium (34% DV) per three-capsule serving
- 2,000 mg Magtein magnesium L-threonate
- Gentler on digestion than citrate or oxide forms
Take the three capsules together or spread across the day, with or without food. Expect a gradual build over several weeks rather than a quick change.
Your practitioner can help you decide whether this form or another magnesium is the better fit.
