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. Magtein is a registered trademark of Magceutics, Inc. and is distributed exclusively by AIDP, Inc. Magtein is protected under US patents 8,178,118; 8,142,803; 8,163,301; and other pending patents.

Noticed improved focus, memory, and sleep quality. NOW Foods is a reliable brand and the quality is consistent. Capsules are easy to swallow. Excellent for brain health. Review: An Answer To My Prayers! 🙏✝️🙏 - God has BLESSED my rest! Sleep, nutrition, and exercise are the three things that are most important for ongoing good health. Do the research as I have and you will learn that this is a true statement! That said, I do also believe in a handful of supplements to help push my body into the right direction. Now Foods Magtein L-Threonate is a newer one I have added to my supplement stack. I did a lot of digging into research to see if this would possibly be a good fit for me. When I add a new supplement to my stack I use the product for 90-180 days before I decide if it's actually making a positive change in my life, however I'm excited to say that just in a couple of weeks I was experiencing a lot better sleep! I take one in the morning and two about an hour before bed. I seem to be able to fall asleep faster and get into my REM sleep and stay there for longer periods of time without disruptions. Yes, I still get up twice a night to use the bathroom "I'm a 50 year old male", however I fall back to sleep quickly without all the tossing and turning with thoughts of dread, because I may not be able to fall back to sleep as my old cycles went. I'm an extremely spiritual man, so as I always do when life throws me some curve balls "trials, tribulations, and adversity" I go to my God in prayer and ask Him to lead me to an answer. I believe that this was an answer to my prayers to be able to get better sleep at night and waking up in the morning refreshed and focused to start a new day. I do plane on doing at least a 180 day cycle of this product and then take a break to see if I will need to keep this in my stack for good or if I'm able to come off of it after a good reboot/recalibration sleep cycle period of time? Only God knows and He will share all the information with me, because He loves me! He loves you too! God Bless and Godspeed. That's my review and I'm sticking to it! 💪😁✌️ 🙏✝️🙏. ## Features - 2 grams of Magnesium L-Threonate for cognitive support* - A patented form of magnesium that readily crosses the blood-brain barrier for utilization in the brain* - Take 3 capsules daily.
