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! Read more

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. Read more

⭐️⭐️⭐️⭐️⭐️ Excellent Magnesium for Brain Health

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. Read more

Unique Magnesium Formulation

One of the few supplements I take that I can tell a significant difference in relaxation and mental focus. Great for sleep as well. Expensive, but also unique in that it crosses the blood brain barrier, which is unique for magnesium and has more efficacy for brain function. Read more

Effective for cognition.

NOW has a reputation for dependable quality and testing. While I by other supplements from Thorne, I frequently use NOW and have been satisfied thus far. Capsules are fairly large, but swallowable. I speculate that they could be opened, but would check with the company first. Not effective for constipation or anxiety, magnesium threonate is the only form to cross the blood brain barrier. Reliable studies have demonstrated safety and cognitive improvement. It took about 2 months for me to notice a cognitive difference. I wasn't brilliant, but I did notice that I had better recall and mental organization. I also take NOW magnesium glycinate for heart and mental health. Am pleased with both. Read more

Surprisingly Effective for Mental Clarity and Focus

I started taking the NOW Foods Magtein Magnesium L-Threonate because I wanted to support my focus and reduce brain fog. After a couple of weeks of consistent use, I genuinely noticed clearer thinking and more mental stamina throughout the day. It also helped me sleep better at night without making me groggy in the morning, which was a huge bonus I didn’t expect. No stomach discomfort either, unlike some other magnesium supplements I’ve tried. This supplement is now part of my daily routine. I love that it’s in a veggie capsule and doesn’t contain unnecessary fillers. It feels like a high-quality product and definitely worth it if you’re looking to support cognitive health naturally. I just wish I had started using it sooner. Read more
