## Overview

NOW Magtein™ delivers 2 grams of patented Magnesium L-Threonate per serving, a unique form proven to cross the blood-brain barrier and support cognitive health, memory, and restful sleep. Taken in a strategic 3-capsule daily regimen, this supplement is USA-made and quality tested, trusted by thousands for enhancing brain function and promoting a relaxed mood.

## Description

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

Review: Powerful - The first time I tried it, I saw a bright circle that expanded and contracted with my heartbeat. I thought I may even fall to the ground. Whatever it was, the impact was almost instantaneous. Since then, I've taken 3 pills everyday, 1 in the morning and 2 in the evening. It feels as if the content is truly getting to my brain. I am focusing better. Able to recall numbers (such as the lock combination) better. Sleeping longer intervals. It used to be every 2 to 4 hours that I awoke. Now I am sleeping through 4 to 5 hours. Waking up only once during the night (and not twice). I've difficulty swallowing the whole pill. I open the capsule by holding the smaller of the two halves on the bottom, then dump the powder onto the center of my tongue. It gets easier with practice. I don't taste anything, unless I spill some onto other parts of the tongue. Then I wash it down with water or coffee. Even works for two pills at a time.
Review: Key to good, natural sleep - Long-time standard for ensuring that I can actually sleep - no small thing! I take 3 or 4 an hour before bedtime (per Dr's suggestion) and before long actually feel relaxed and sleepy. This just does not happen for me without Magtein. Magtein facilitates natural feeling and restorative sleep cycle for me. I feel awake and refreshed in the morning -not sickish as I did when I tried Valerian. Worth the price, from a respected brand. I am sticking with Magtein!

### ⭐⭐⭐⭐⭐ ⭐️⭐️⭐️⭐️⭐️ Excellent Magnesium for Brain Health
*by Y***R on October 4, 2025*

I’m 42 years old and have hypothyroidism, which often leaves me dealing with fatigue, brain fog, and memory issues. I decided to try Magtein (Magnesium L-Threonate) because of its reputation for supporting cognitive function, and I’m really glad I did. Unlike other forms of magnesium I’ve tried, this one actually seems to make a noticeable difference. Since starting it, I feel my concentration, focus, and memory are sharper, and I don’t experience the same level of mental fatigue throughout the day. I also like that it’s vegan, non-GMO, and comes in capsules that are easy to take. It has become an important part of my supplement routine, especially to support brain health and learning capacity, which can sometimes be more challenging with thyroid issues. Overall, this is a high-quality supplement that truly delivers on its claims. I would definitely recommend it to anyone who wants better focus, memory, and mental clarity.
