Non-negotiable supplement
This is a non-negotiable brain supplement for cognition. I've trusted the NOW brand for decades, when you could only find it in health food coops.

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.

Helps me fall asleep and helps my brain!
I have this product on subscription because based on my research this is the only type of Magnesium that can get through your blood-brain barrier to help your brain and to help you sleep. I think it does make a difference in my ability to fall asleep. I take it about 30-45 minutes before bed and I rarely ever have trouble falling asleep. I take two pills at night and one in the morning as the product recommends. I've used many NOW products over the years and I've never had any complaints with any of them. I'd highly recommend this product for your brain health and sleep!

I use Now Foods Magtein for a good nights sleep.
I was not getting good sound sleep at night. A couple months ago I read an article that said that low magnesium levels can cause sleep problems especially as a person ages. I discovered Now Foods Magtein on Amazon and decided to try it as my magnesium source. I take two capsules at bedtime and one in the morning. I sleep soundly all night long now. I just ordered my 4th bottle and it works perfectly for me.

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.
