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.

Natural color variation may occur in this product.

Helps me sleep through the night

Posted by iHerb Customer on Oct 30, 2017 | Verified Purchase

I have really been struggling with Restless Legs Syndrome. I'd twist and turn and wake up at least once during the night, had to get up, stretch etc for 30 minutes or so before I could go back to sleep. Sometimes several times a night. With this magnesium supplement I noticed a sudden improvement in my symptoms - I hardly ever get up in the middle of the night now and usually sleep through the night without waking at all.

Thanks for your feedback!

For those of you who are interested in increasing your cognitive abilities, this is the route to go. Developed by MIT, this product truly works. It is the the only form of magnesium that is able on its own to penetrate the blood brain barrior. I have a very special way of taking this that has been giving me wonderful results.

I give it to my mother who has dementia and is quite restless and worried. Magtein makes a great difference for her (and for me), she doesn't call 20 times a day! Great product!
