Source Naturals Magtein Magnesium L-Threonate 667mg - 180 Capsules

As is noted above, Magnesium L-threonate penetrates the blood-brain barrier, and hence it can purportedly support cognitive function and brain health. This makes the magnesium in magtein distinct from many others on the market, including magnesium oxide (poor bioavailability), as well as magnesium chloride, lactate, and aspartate, which have better bioavailability but which also don't penetrate the blood-brain barrier. Magnesium is an important part of everyone's diet, but corporate farming methods have depleted its presence in soil, and hence, in our diets. It appears somewhere from 60-80% of Americans are deficient in magnesium, and low magnesium levels are associated with a variety of conditions, including hypertension and heart disease, type 2 diabetes, osteoporosis, and migraine headaches, among others. We landed upon magnesium l-threonate because magnesium is noted to have calming properties. Our son is a bit hyper - so after finding out about the benefits of magnesium, we found out about l-threonate and then researched different brands. On a weighted assessment, Megtein is the cheapest l-threonate product currently on the market, so our decision was pretty easy. I can't say if it was a coincidence, but shortly after starting on the Magtein, my son's reports from school improved dramatically. He was more focused, and his classroom performance improved correspondingly. He went from being the kid the teacher dreaded to being one she obviously, really liked. It was a stunning turn-around. The pills aren't huge, and he has no problem swallowing them. Was it solely due to the Magtein? I can't say - we also started him on probiotics, and we gave him a good vitamin K and D supplement as well, but something has changed. And I'm not going to mess with success, so he'll be on the Magtein for a while. I've been taking the Magtein as well - I can say it causes me to have more dreams and deeper, more restful sleep than I've had previously. In all, I'm a huge Magtein fan, and will remain so.

I have been taking Magtein for several months. After just a few days, I began to feel this comforting sense of peace and joy. Since I have some genetic issues with absorbing folate, I have been taking numerous supplements for years to treat a number of conditions. Hence, I am already on some of the vitamins and minerals that should be taken with Magnesium. Especially, B6 and D3. Off and on over the years I would take Magnesium to treat restless legs, but it was only sporadic and not l-threonate. Knowing there is a strong family history of dementia, I decided to switch to Magtein in the hopes that it might delay the onset of Alzheimer's. Not for one minute do I believe this will be a miracle cure, but it might be part of a larger arsenal of preventative measures. Regardless, this is now one of the top 5 things I have discovered to improve my daily life with lessened anxiety and heightened clarity of thought and deeper sleep. I recommended this to my adult son and he promptly hijacked my bottle for himself! I am making him pay me back. He has suffered from anxiety for over a decade and cannot tolerate the side effects of numerous anti-anxiety prescriptions. After taking this, he reports his anxiety has lessened a great deal and that his wife is grateful. He also reports that he had been experiencing brain fog and had begun slurring some of his words. Those two things are now better. This is the first medication/supplement he has tried that he has wanted to keep taking other than a multivitamin. We are waiting to see how this affects my mother who is in the middle stages of Alzheimer's. I am hopeful that it will also ease her anxiety and I don't have any unrealistic expectations that it will treat her dementia. But, if it does . . . wouldn't that be great! Alas, anything that will help keep her calm is a good thing. She has had very bad reactions to prescriptions in the past and refuses anything "for her brain." We can open the capsule and mix the powder into her food if she refuses it in pill form. We have only been using this for a week and just one a day, so too early to report.

Excellent Product. After much research, this rose to the top.

This product made me feel like 15 years younger in terms of thinking power. This is the precise magnesium supplement I needed to get my cognitive skills back.I had shingles 6 months ago and since then my ability to think clearly,logically and visualize ideas had decrease considerably. My anxiety levels were through the roof. Doctor suggested taking a magnesium supplement to help get a clear head. I took 2 pills with water first thing in the morning on an empty stomach. 1 hour later I found myself more energetic than before. That whole day I was able to focus on my task at hand. My thinking was clear, calm and focused. I coupled this with 500 mg of L-tyrosine to relieve anxiety. That was the best thing I did. My anxiety was down to zero and mental capacity was back to normal. My daily dose for zero anxiety and super charged brain power is 500 mg L-Tyrosine and 2 caps of Magtein. I have been taking this for a week and consistently seen benefit. Until I figure out a way to improve my diet to get the right nutrients for my brain and body, I will continue taking this supplement.

I found this product to be as advertised and have reordered it several times now. It is cost effective, works as advertised, and easy to order.

I got turned onto this form of magnesium because it breaks the “blood brain” barrier. In theory this leads to a nootropic effect and helps memory. I don’t know how much it has helped my memory BUT I can say it doesn’t upset my stomach (like citrate) and in the morning my urine is not cloudy (like citrate and oxide), which tells me my body is absorbing more of this form. I will continue to buy L Threonate form of magnesium and this brand has the best price.

Product as described. I am doing everything I can to protect my brain and this product claims to breach the blood/brain barrier. Our bodies are deficient in magnesium and this helps load up your system. Will re-order.

Nice staff

Product arrived on time. I had no issues purchasing

毎日欠かさず飲んでいます。 安心感があります。 ありがとうございました。

メンタルの改善を目的にマグテインを購入しました。 目的の効果とは違いますが、不思議と漢字が書けるようになりました。もともと漢字を書くのが苦手で、読めるけど書けない、なんとなくは解るんだけど書けない、みたいな感じだったのですが、マグテインを飲むようになってから不思議と漢字が書けるようになって驚きました。脳に効いているんだと思います。
