Label statements
Directions: Suggested Usage: Take 3 capsules daily in divided doses (take 1 capsule in the morning and 2 capsules two hours before sleep).
Formula: Contains: Magnesium (Mg) is an essential mineral best known for its role in bone and nervous system function. 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 Mg are not easily absorbed into the nervous system. Magtein is a patented form of Mg 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.
Precautions: Children: Caution: For adults only.
Precautions: All Other: Like other magnesium products, Magtein may induce sleepiness, drowsiness or headaches at first. Reduce the dosage, consult a doctor or discontinue use if conditions persist for more than one week.
