  • Breakthrough magnesium supplement for mental sharpness--30 day supply!



  • Developed by MIT researchers, with 7 patents pending



  • Only form of magnesium shown to cross the blood-brain barrier to promote optimum levels within the brain


Magnesium L-Threonate featuring Magtein™ promotes healthy neuronal activity for the support of healthy cognitive functions like recall, learning, decision making and spatial recognition. Traditional solutions for cognitive support involve stimulating the neurons to promote peak brain function. But over time, this can lead to burnout and have the opposite effect. New Magnesium L-Threonate works differently. Its patented form of magnesium nourishes the brain to help hold neurons in a state of relaxed readiness, facilitating the free exchange of electrical impulses that transfer information and keep our minds sharp and clear. Preliminary research suggests great potential for this new magnesium—the only form known to readily cross the blood-brain barrier and function within the brain. Animal studies have shown benefits for learning, memory and even mood. Human trials are underway, but why wait? Protect the power of your mind today with Magnesium L-Threonate from Swanson Ultra.

better than expected results bought this to help me with my cognition and production of brain neurotransmitters. This has greatly improved my quality of sleep, calmness throughout the day and overall mood has improved. Swanson products are the best around. May 13, 2012
Brain fog cleared! I have been taking Swanson's Magnesium L-Threonate for about two months and definitely feel that my brain is sharper and firing on all cylinders. It helps my work and I think and act more quickly. I will make Swanson's Magnesium L-Threonate one of my daily supplements indefinitely. Although fairly pricey, Swanson's is the best deal and quality on the market. Brain fog? Gone! April 5, 2012
works for me! I've been taking this product as recommended for about 3 months. I noticed that my mind was much clearer and more focused and alert within a day or two after taking my first dose. Before taking this product I felt the need to take a nap almost every afternoon. That need is now gone. Before taking this product I would rarely dream when asleep at night. I am now dreaming again. I am definitly thankful for this product and will continue ordering it. February 16, 2012
Enhanced Mental Clarity After taking this with Pterostilbene for a month, I'm a believer. My mental clarity and focus are better than they have been in my whole life. I wish I could get this with the Pterostilbene already added. Priceless. February 8, 2012
Best purchase from Swanson ever. I am 72 years old, retired and work from my home as a day trader, and have been taking this supplement for three weeks. After remaining nearly inactive in the stock market for the past six months, due to the inability to think clearly. I am now trading and making money again. My sleep is deep with very vivid dreams, and my mind is clear. This product is well worth its money, and I plan to order again. February 3, 2012
Vivid dreams I have been taking this supplement for three weeks. I am not quite sure what to expect. The one thing that I do know is that my sleep is deep with very vivid dreams. I think after a few months I would be able to conclude if the product is worth the money. I will continue since I have read the research on this product. I will know more soon.... January 14, 2012
Worth using You need to take this product for at least a month to start seeing results. I've read several papers on this product and it does cross the blood brain barrier. Like I said, give it a month to see real results, especially if you are over 40 years old. December 18, 2011
Magtein Magnesium L-Threonate I have been taking this product for about 1 month. I feel less scattered, have an improved ability to rememeber things and in general seem more in control. In addtion, my sleep has improved. It is a much deeper sleep than before. I would recommend this product. I am 53. December 12, 2011
Worth a Try I am grateful to Swanson for bringing this news and product into my life. I do not trust buying from "other" sources who do not appear to be directly linked with the researcher that developed the product. Therefore, I have faith in Swanson to provide a pure and safe product. I hope the label reflects the physical values in the caps. November 29, 2011
NOT IMPRESSED I've been using magnesium daily all my life. All types have been calming for the brain, nerves and also good for bowel movement. Magnesium L-Threonate was suppose to be special since it crosses the brain barrier. It did nothing for me at all. Could'nt even notice I ever took it. Don't waist your money on this product. I will not be ordering this product again. November 27, 2011
