Source Naturals Magtein Magnesium L-Threonate Capsules (667mg, 180 Pieces)

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.

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!

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 read in a review below something very very important about dosage. This is important because overdosing is dangerous and the labeling is misleading... "Consumers need to be aware that the 667mg mentioned in the product description refers to the total amount of Magnesium L-Threonate per capsule. However, only about 7.2% of this is pure elemental magnesium, which amounts to approximately 48mg per capsule. The recommended serving size is 3 capsules, providing 144mg of elemental magnesium. This is grossly deceptive in my view."

I can’t say that it doesn’t contain magnesium l-threonate. However, it does contain maltodextrin (highly processed sugar), which is something I choose to avoid and seems unnecessary in this supplement. I should’ve read the label well before choosing the cheap option.
