Source Naturals Magtein Magnesium L-Threonate 667mg Supports Focus, Mood, Healthy Memory, Cognitive Function, Sleep* - 90 Capsules

So, you try a supplement which is supposed to help your brain and your memory, but you know in the back of your mind that it won’t. But guess what? This one did! I started remembering things I forgot that I knew. Even little details! I was taking it for about three months when it dawned on me that I was having this memory recall. Definitely worth buying. As an added bonus, it helps keep your digestion regular because it’s magnesium.

This is an excellent product. It passes the blood/brain barrier. Helps generally and in preventing headaches.

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.

These supplements help me understand things better. And go to the bathroom better. Thanks.

A little google research will turn up a number of articles alleging that 70-80% of Americans are now deficient in magnesium, due to changes in diet (less consumption of leafy green vegetables, etc.) and so-called "corporate farming methods" that have depleted the soil of this essential mineral. There are a number of critical benefits to supplementing with magnesium, which including bone health, by balancing out calcium (there are plenty of studies now showing that calcium can't be absorbed properly without magnesium), moderating heart and blood pressure risks, neurological - improving sleep and concentration, preventing migraines, etc. It's quite a list. I started getting magnesium for our household to address some anxiety and restlessness issues, as well as some muscle cramps, and it _appears_ that the supplements we've used have had the desired effect. You can find the NIH fact sheet on magnesium linked here: http://ods.od.nih.gov/factsheets/Magnesium-HealthProfessional/ Turning to this supplement: there are various types of magnesium supplements that you can buy, including magnesium oxide (low bioavailability), magnesium sulfate (think Epsom salts), magnesium citrate (decent bioavailability), magnesium bisglycinate (high bioavailability) and magnesiums l-threonate. Of these types, I've used bisglycinate (as in the Viva labs pills and others) because of its high bioavailability and source naturals l-threonate because of its documented neurological benefits in improving brain function. I tend to steer away from others because, despite being less costly, they are also less effective. You get what you pay for, to a degree. I certainly would never consider a magnesium oxide supplement, as in my opinion that's basically a waste of money. The Viva Labs magnesium comes in the form of 240 decently large, but readily swollowable, chelated tablets. They're somewhat larger than the Source Naturals L-Threonate capsules that I'm currently taking, and the Viva Labs tablets are bit harder to get down, but not so large that it's a problem for me. I can't tell the difference when I switch between them, to be honest. That said, when I started taking the Magtein, I found I slept much better and started having some fairly intense dreams - this has continued while taking the Viva Labs magnesium, so I assume the absorbtion is at least somewhat comparable. As far as price - the Magtein is far more expensive then Viva Labs chelated magnesium, although I think it's the cheapest of the L-threonate magnesiums - currently listed at $21.69 for 90 capsules, or 24 cents each. The suggested use is 2 in the am and 1 at night - 3/day or 72 cents a day. Viva Labs is listed at $18.99 for 240 tablets, or approximately 8 cents each. the suggested use is 2 tablets twice a day, for a cost of almost $.32/day. Simply put, the Viva Labs magnesium costs less than half of the Source Naturals L-Threonate magnesium. That doesn't mean it's necessarily the right choice - I think everyone should do a little research and also decide exactly what they are trying to accomplish. Source Naturals L-Threonate might be the right choice to help with memory and neurological issues - Viva labs might be desirable for coronary issues, muscle relaxation, and teeth and bones. Regardless, I suspect both these products work well, albeit possibly to different degrees, and both of these products are worthy of consideration.

Amazing product, leagues above the rest

I've been taking some form of magnesium for years now. I was really excited after reading about this because I suffer from migraines and thought this might help. I've taken it about 5 days and it just makes me feel really weird. Maybe my magnesium is low in my brain and cns and its some sort of reaction to getting magnesium in there. I felt very awake on it, so that was nice, but also emotional and jitterish. Not like caffeine jitters. Maybe I just haven't taken it long enough for the kinks to work out. It also causes me some heartburn which I wasn't expecting. Going to give it more time and see if things improve, but at this point it's not the panacea I was hoping for. ****update*** I took a break from this for a couple weeks and started back up with 1/2 the capsule. I am (now) loving it! I don’t have the jittery feeling any longer and it doesn’t seem to be causing the heartburn issue as much. It just makes me feel good. I feel awake and calm. I don’t seem as fatigued or overwhelmed by physical or mental tasks. I actually look forward to taking this because of how good it makes me feel all over. But it’s not an overwhelming jolt of feel good, but a subtle yet noticeable sense of well-being.

I’m in my sixties, and have been in the horticultural field for over 40 years. Thirty years ago, I held in my memory hundreds of scientific names of plants. When I was in my twenties, I took an exam where 165 plants or plant parts were displayed at random from a study list of 500. The requirement was to give the Latin name with the correct spelling. I missed 3 out of the 165. Over the last twenty years these names have faded, and before taking this form of magnesium, I had lost all but a handful. I would drive down a street, see a tree, and struggle with remembering the name but couldn’t recall. A few weeks after beginning a daily Magtein regime, I was watching a movie on TV. This movie took place somewhere in a tropical or sub-tropical city - Miami or Bangkok, etc. – I really wasn’t paying close attention to the movie, as it was playing while I was doing other things. The scene involved a camera in a car that was moving down a street. I saw a palm tree, and immediately recalled its name: Syagrus romanzoffiana. I didn’t think much of this, because I sometimes remember plant names at random times, and them may forget that name the next day. I then saw another plant I recognized, then another, then another. I stood there in my living room glued to the TV and named the plants as the car moved down the street. It was then I remembered that the palm, Syagrus romanzoffiana, has a problem with being deficient in magnesium in some soils, the same element that was no-doubt helping my memory! Over the next few days I started to recall scores of plant names, and even recalled the wholesale prices from plants I sold 40 years ago. It was not only plant names, but people and places, classmates from high school, clothes and toys from childhood, it all came flooding back. I can say I still forget where I put my car keys, to get milk or eggs at the store, but these things have always been a problem for me. So for me, this product has been amazing!
