This is a good product. I use it often.
I buy this product repeatedly. It helps me to sleep and keeps away the leg cramps that I often get.. I would recommend us. I am 156. I take two capsules a night.

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.

โญ๏ธโญ๏ธโญ๏ธโญ๏ธโญ๏ธ Excellent Magnesium for Brain Health
Iโm 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 Iโm really glad I did. Unlike other forms of magnesium Iโve tried, this one actually seems to make a noticeable difference. Since starting it, I feel my concentration, focus, and memory are sharper, and I donโt experience the same level of mental fatigue throughout the day. I also like that itโs 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.

Truly Effective Magnesium SupplementโGreat for Sleep and Stress
Iโve tried various forms of magnesium supplements, but NOW Brand Magtein has genuinely impressed me. Magtein is unique because it specifically helps calm down overactive glutamate in the brain, meaning itโs great if you're someone who struggles with overstimulation, stress, or caffeine jitters. I've personally noticed it helps me fall asleep quicker, and most importantly, I wake up feeling refreshed and mentally clear. One minor point: the bottle doesn't come with a moisture-absorbing packet inside, so be mindful to store it carefully to avoid moisture. That said, it's an outstanding value for the price compared to similar Magtein products out there. If you're looking for magnesium that actually helps manage stress, enhances sleep quality, and reduces overstimulation, I wholeheartedly recommend giving this a try. Itโs become a staple for my nightly routine.

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 didnโt expect. No stomach discomfort either, unlike some other magnesium supplements Iโve tried. This supplement is now part of my daily routine. I love that itโs in a veggie capsule and doesnโt contain unnecessary fillers. It feels like a high-quality product and definitely worth it if youโre looking to support cognitive health naturally. I just wish I had started using it sooner.

Noticeably improved sleep quality and trustworthy brand for supplementation
I started taking Magtein specifically for cognitive support and focus, and I have been using it for several months now. The difference from standard magnesium supplements is that this form is designed to cross the blood-brain barrier, which is why it is marketed for cognitive benefits rather than just general magnesium supplementation. For me, the most noticeable effect has been in sleep quality. I sleep more deeply and feel more rested in the mornings when I take it consistently before bed. Whether that is purely the magnesium effect or the specific L-Threonate form, I cannot say definitively, but the pattern is consistent enough that I keep repurchasing it. NOW Foods is a brand I consistently trust for quality and transparency, and this product is no exception. The veg capsules are easy to swallow and there is no upset stomach which can happen with some magnesium forms. Three capsules per serving is on the higher end but the capsule size is manageable. For the supplement category, this is one I would recommend to anyone specifically interested in the cognitive support angle.

Mejora animo, concentraciรณn y sueรฑo
Si, es original. Desde la prepa (15 aรฑos) suelo dormirme tarde (2am) hoy me cuesta conciliar el sueรฑo por lo mismo, ademรกs el estrรฉs, ansiedad de trabajo y la familia empeora mi calidad de sueรฑo. Magtein no solo ayuda a dormir mejor si no en general me concentro mejor, estoy de mejor humor y me ayuda con mi dรญa a dรญa, nunca vi lo importante que era hasta que se me acabรณ y me lo dejรฉ de tomar y vi el gran cambio, desde entonces procuro estar bien surtido.

Product looks low quality at first inspection, content spiled outside capsules into the container.
Paid 43 euro/90 capsules and the product looks suspiciously low quality at first inspection. A lot of the content just spiled outside the capsule into the container.

Amazing magnesium L-threonate
There is no doubt that Magnesium L-threonate is the best form magnesium but it is bit costly than gluconate,but it is worth of buying. For better results need to take 4-5 capsules a day because elemental magnesium contain is only 144 mg and for adults more than 400 mg per day is required.
