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.

Suggested Use

Take 3 capsules daily in divided doses (take 1 capsule during the daytime, preferably in mid-afternoon and take 2 capsules one hour before sleep).

Other Ingredients

Cellulose (capsule), rice flour, magnesium stearate (vegetable source) and silica.

Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish or tree nut ingredients. Produced in a GMP facility that processes other ingredients containing these allergens.


Caution: For adults only. 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. Consult physician if pregnant/nursing, taking medication, or have a medical condition. Keep out of reach of children.

I feel more alert mentally and energetic after taking this form of magnesium pills. It stopped my night leg cramps too. This product is highly recommended.

My Dr recommended this product as it crosses into the blood brain barrier making it effective in its delivery to do its job especially at night for relaxed muscles.

Now Mag L-Threonate

Posted by iHerb Customer on March 3 2018 | Verified Purchase

It greatly improved my panic attacks and depression. Eventually I hoped I can be off my long term antidepressants which have side effects on my memory!! My only complaint is the price which will be quite costly if taken 3caps/day.

Thanks for your feedback!
