  • 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.

Really Works This really works! I'm 67 and been taking it for about 2 years now. I recall names places and events from many years ago that I thought had forgotten. Also, helps with current events and processing information a lot faster. This is not snake oil and highly recommend it. I also noticed that I have very vivid, in color dreams and no problems sleeping. I usually take one in the morning and one at night. Best price is with Swansons! July 26, 2014
Remember...what? I still forget things, but I remember that I forgot them way sooner now. So I do still forget the grocery list, but I remember that I forgot it at the bottom of the stairs, instead of in the middle of the grocery store. Improvement, yes? I do like the dreams that are coming back. I can even remember some of them! February 22, 2014
Calms my nerves I take one of these at bedtime. Seems to calm me down the next day. I also take one 5-HTP and one Lemon Balm, Passion Flower, Skullcap Complex. Also, I made a powder of Melatonin, GABA, Tryptophan, DHEA, D3 and Suntheanine. I take about one capsule of that powder too. I tend to be hyper and this regimen mellows me out. January 9, 2014
Helpful This version of Magtein seems to have improved my memory, taken with Alpha-GPC daily. It's pricey, but I will continue, as long as I see benefit. December 16, 2013
Great product I have read about the importance of this mineral to my diet. I am happy with the quality. November 21, 2013
undecided I have been using this product for about three weeks. I am not sure if it is helping or not. I will use for a little while longer before making a final decision. October 3, 2013
Memory aid I have found a rapid improvement in my memory function since I started taking this, for about 5 weeks now. I certainly plan to continue. September 9, 2013
Even Mercola likes this After reading about Mg-L threonate on Mercola's site I decided to give it a try. Kinda expensive; but I imagine Swanson has the best prices. I take just two in the morning and I take melatonin at night. I do have pretty vivid dreams. I took a long hike after my morning dose. I felt more energized than normal. I like the pep I get after taking this. August 6, 2013
Unique Magnesium Magnesium L Threonate is the most unique form of magnesium. You must read the studies performed on this type of magnesium to appreciate its capabilities. August 5, 2013
Magnesium L-Theonate I've taken these for a few months now. Not working as fast as I'd like them to, but I do believe they are making some difference. July 8, 2013
FOCUSED! It crosses the blood brain barrier and keeps me focused! May 16, 2013
Magnesium Threonate in combination with Alpha GPC I was willing to give the Magnesium Threonate and Alpha GPC a serious try for a few weeks, and now I have been using them daily for several months. It took a couple weeks, but when they kicked in, the increased level of focus, energy, memory retention, and cognitive ability makes them worth the price, which by the way, is considerably cheaper with Swansons fine brand. Before, my stressful hospital job had frazzled my nerves and exausted my mind to the point where I was forgetting numbers I had seen moments before. (I would like to point out I am in my mid 50s'). Now, I'm doing serious studies and retaining (AND understanding!) things that I never understood before using these great supplements. I recommend them to the stressed- out worker, the student, and anyone else who wants a large improvement in their cognitive abilty. Whereas it is true, not all supplements will work for everyone, these have a growing reputation, and are well worth a try. Just allow them a few weeks to begin their good work, like any good supplement usually needs.. These supplements ROCK! May 2, 2013
Very effective Although the L-threonate form of magnesium is new on the market, it has impressive clinical evidence of it's ability to dramatically improve synaptic density and neuronal plasticity. April 12, 2013
Good value Good value on mag threonate. Taken at bedtime to help relax. April 2, 2013
thought I was losing my memory but also had shaky hands...turns out it was a deficiency...within days of starting on the caps I noticed a difference...after 2 months I can say that it's definitely working...thank goodness ! March 21, 2013
Satisfaction This product, for me it would require several bottles to really test its efficacy toward its proposed goal & usefulness, I can't tell a difference. maybe the formula is Weak! March 20, 2013
Improved Memory After reading exciting reviews about magnesium-L-threonate and the possibility of improved memory function I was most anxious to try it. As usual, I went to Swanson's as a trusted source and for pricing that would be more than competitive. As a 55 yr. old menopausal women, I found this product very helpful and have made it part of my daily extensive Swanson regiment. March 11, 2013
absolutely delighted so happy with results of using this product that i want to order more and would definitely reocmmend to my friends. March 4, 2013
Did not work for me I have taken Magtein magnesium for three months at 3 capsules per day. I did not find any noticeable difference in memory. This product has been only tested on animals and not on humans. I went back to my regular old magnesium. This product is too expensive for its purported benefits. I do not recommend. February 8, 2013
I wouldn't discourage others from trying this supplement, even though I didn't notice any benefit. I do take other forms of magnesium daily - maybe I didn't need this - I don't know. It didn't improve my brain function. January 27, 2013
Calming Does what it is supposed to do, and quite well. August 31, 2012
why the confusing label? There is no where on the packaging that indicates simply exactly how many gm/mg PER CAPSULE. there is just a chart on how much and percentages you would be getting in am dose and pm dose. Which is divided into Magnesium(from Magtein magnesium L-threonate) AND Magtein magnesium L-threonate. I am not new to deciphering supplement bottles, but find this one very confusing and hard to compair side by side for what I am getting. May 29, 2012
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
