# NOW Foods, Magtein – Magnesium L-Threonate, 90 Caps

# **NOW FOODS MAGTEIN – MAGNESIUM L-THREONATE: PROMOTES BRAIN HEALTH**

Magnesium supports your body with many functions:

- To maintain normal muscle function

- In bone maintenance

- In energy metabolism

- To reduce fatigue and exhaustion

- The functioning of the nervous system

Recent research has demonstrated that it is also critical for normal brain health and normal cognitive function by maintaining the density and stability of neuronal synapses. However, most forms of Magnesium are not easily absorbed into the nervous system. Magtein® is a patented form of Magnesium L-Threonate that readily crosses the blood-brain barrier for utilization in the brain. Laboratory studies indicate that Magtein® supports brain health and may facilitate learning and memory, as well as a relaxed mood.
