For over 40 years, Life Extension has been a trusted leader in providing high-quality supplements, adhering to stringent GMP standards and rigorous quality control.
Magnesium is a vital mineral essential for bone health, nerve function, and overall well-being. Recent research highlights its crucial role in brain health and cognitive function, supporting the density and stability of neuronal synapses. However, many forms of magnesium are poorly absorbed by the nervous system.
Magtein® is a patented form of magnesium L-threonate that readily crosses the blood-brain barrier, ensuring superior absorption and utilization by the brain. Studies show Magtein® supports brain health, improves learning and memory, and promotes relaxation.
As a dietary supplement for adults, take three (3) capsules daily with water, or as directed by a healthcare professional. The daily dose can be divided (e.g., 1 capsule in the morning, 2 capsules two hours before bed).
