  • MEMORY, FOCUS & COGNITIVE BOOST – Magnesium is essential for overall brain performance, but not all magnesium supplements are easy to absorb. Based on the latest research, we used magnesium L-threonate. Preclinical studies have shown that this highly absorbable form of magnesium can improve communication between brain cells because it can cross the blood-brain barrier and influence signaling pathways associated with learning, memory and focus.
  • MAINTAIN IDEAL MAGNESIIUM LEVELS – Magnesium does wonders for your brain, but it’s also important to more than 300 biochemical reactions in your body. Unfortunately, most of us don’t get enough magnesium from our diets, and optimal levels begin to decline as we age. That’s why supplementing with (easy-to-absorb) magnesium is a great complement to your healthy lifestyle choices, especially over time!
  • MAGNESIUM L-THREONATE HELPS YOUR BRAIN WORK BETTER – Your daily activities demand focus and attention. Still, over time, the little details can slip your mind and you find yourself looking for sunglasses that are on your head. That’s where our formula comes in! Our magnesium L-threonate is easy for your body to absorb into the nervous system and your brain, where it helps maintain the crucial connections between your brain cells.
  • INGREDIENTS MATTER – Sourced using only the finest raw ingredients with the purity and potency your body deserves. The majority of our products are non-GMO, gluten-free and manufactured in the USA—and a Certificate of Analysis is available for every product we produce.
  • LIVE YOUR HEALTHIEST LIFE – For over 40 years, we’ve been developing advanced, effective formulas made with the highest standards and based on the latest scientific findings. We believe the answers to a healthier, richer life are within reach, and that rigorous scientific research is the path to get us there. Our formulations are created using the ingredients and dosages used in the studies that inspired them, ensuring that maximum bioavailability and efficacy is achieved.

    I take magnesium supplements anyway since it isn’t easy to get from food with the declining magnesium levels in soil. I had read a lot about the threonate form having positive effects mentally and was excited to try it. I chose life extension because I like their products.

    Sadly after almost two bottles of this, I had no noticeable effects. Maybe because I was already taking a different form of magnesium and was not deficient in the mineral, or maybe it just doesn’t work for me.

    It doesn’t mean it won’t work for others, just nothing extra for me so I will be switching back to my previous magnesium supplement when I finish this bottle.

    Magnesium l-threonate does not agree with me! Other types of magnesium-no problem, but this caused a reaction so severe that I will NEVER swallow another Mg l-threonate capsule again. I bought this for sleep; my brother and his wife use it, and they like it very much. But for me, it caused some kind of deep cramping in my thighs so excruciating I can find no words to describe it. It did not seem like a muscle cramp, but more like a vascular cramp, as if something had a hold of your femoral artery and was cruelly twisting it. I do know pain. I had to undergo abdominal surgery while conscious without anesthesia on one painful occasion, and there have been several other unfortunate episodes, so believe me when I say this was painful. Painful enough that the thought of a recurrence of this pain actually strikes terror in my heart! I I know this sounds very melodramatic, but it is the truth. I do not believe my reaction was due to an interaction of this supplement, as I was not taking anything else at the time. Also, I am generally healthy, ultrasound has shown no evidence of any vascular plaque or ischemia. Also, it wasn’t just this brand, as I tried several brands. The cramping occurred on 2 occasions, both times when I took this supplement, within a couple hours of taking it. I also enjoyed a vascular headache with it., both times when I took it. Not fun, but nothing like the cramping in the legs. Outside of these 2 episodes, I am not troubled with cramping.
    Anyway, I don’t think there is anything wrong with this brand, I know most people find it very useful. I have never had a reaction like this to any supplement. I hope nobody else ever has a reaction like I did.

    This is my third brand of Magnesium Threonate and definitely the best. I am 64, still working. My job is very stressful and mentally and physically demanding. I observe better memory, much more mental and physical endurance. I highly recommend this product and I hope it will do the same for you (I take one in the morning and two in the evening). PS. I almost never write reviews.

    I take this with a mix of other chelated magnesiums: taurate and bisgycinate (and some inevitable citrate as supplements seem always to be bulked up with this). In combo with better potassium and calcium, they have definitely stopped my night leg cramps. I switched from a supplement containing mostly mag oxide which is basically non-absorbable and over about 3 months they stopped.

    whether it does anything for the brain as claimed i dont know. if it does it will be fairly long term

    In my experience magnesium is one of the most essential things to supplement due to cramps.

    I take this in conjunction with another supplement that I’ve also found helpful and wrote a review on. I can’t speak to its use alone, so I’m sharing the review I wrote for the other supplement:

    I’m someone who has had trouble falling asleep and staying asleep since I was probably 8. 22 years later now, I’ve tried many things short of the addictive route to help with sleep. Yoga nidra meditation is helpful, but sometimes it just doesn’t work. Hypnosis is helpful, but sometimes my ears get overstimulated from listening. Therapy helped quite a bit, as did getting on a schedule and a strict bedtime routine, but there are still occasional nights where I wake up at 2am, can’t get back to sleep, and have to commute over an hour to work, then back in the evening. I also tried a magnesium citrate or glycinate, which helped a lot initially, but then the stress of grad school overrode the positive effects that the magnesium had on my sleep.
    Fast forward to last when I listened to Dr. Andrew Huberman and he recommended l-theanine and magnesium threonate. I ordered them right away after scouring reviews to be sure I got a good product. I’ve taken this with the l-theanine every night an hour before bed and it works very well. If you see the screenshot I’ve attached, Wednesday was the first night I took it and you can see how different my sleep duration was from the previous few nights, and how my duration has stayed consistently high for Thursday and Friday night. I highly recommend this product.

    I’m 72 years old. I have neuropathy from diabetes for the last 6 years. My step-daughter, Stephanie, says a friend of hers uses this to help with her neuropathy. I said, “I’ll give it a try.” I currently was taking 500 mg of a cheap magnesium supplement I buy at local drug stores. I looked on Amazon and found a compound called, “Neuro-Mag®” brand “Magnesium L-Threonate”. I orderd a bottle. 1 months supply. I start taking the 3 pills a day.

    They are 144mg of Magnesium L-Threonate in each pill. 500 mg of magnesium is the minimum daily recommended (MDR) requirement to keep a human healthy as listed by the US Government. I’m taking slightly less than the MDR with the 3 pills. Magnesium is a required chemical for the human body. Magnesium enables electrical activity within the body and affects neural (nerve) activity. Neuropathy damages neural activity. Make sense to me. Take for neuropathy.

    It’s the afternoon and I’m at Homedepot buying paint. I customer across the paint counter makes a pun on another customers comments. I make a pun off his pun. And then another pun off that pun. And then another pun and then I shut up.

    I realize what I have done and think. My brain is racing. It seems as though the left half is making up the puns and right half is speaking them. Simultaneously. I mildly freak-out. “Keep cool, keep cool”. I say nothing, buy the paint and go home. I looked up the stuff I’ve been taking online. I find one and only one entry. A Japanese test study done on old rats a few years back. I read it.

    “After 21 days the rats being tested are able to run the maze approximately 20% faster than the control rats.”

    I go to Amazon to see when delivery of the magnesium was made. Exactly 22 days ago. I have been taking it for 21 days. My translation: it makes your brain work more efficiently (better). AFTER 21 days of continuous use.

    I think of what happened at Homedepot. I felt like Robin Williams. With one half of my brain comin’ up with the jokes and the other half delivering them rapid fire while the first half thought up the next joke. I was truly, “The man with two brains”. I’m going to write a film script with that title.

    I look up the intended function of the product. It says, “Enhances Memory and Cognitive Function”. Nothing about neuropathy. The effect on my neuropathy in negligible. Frankly, I get better direct relief from Epsom salt foot soaks.

    I looked up in my Amazon order history of when I first started using Neuro-Mag®, Its been about 2 years. I told my new doctor in mid-2018 about Neuro-Mag®. I said to her, “I will never stop taking this product. It works for me.” I asked her to “monitor me.” She said, “I’ve never heard of it.” And agreed to keep watch on me. I am your guinea pig. I alone, am responsible for what it does to me.

    I’ve told others about Magnesium L-Threonate. They look at me like I’m from the Mars. I don’t talk about it much now. I realized I’m an oddball. Odd for taking it, odd for talking about it. I did tell Stephanie it works for me. I will tell anybody who asks. “Yes, it works for me.” I’m pretty much a failure at getting others to do what I’m doing. Yeah, it does costs a $1.00 per day. And yes, I will stop taking it when I’m dead. I like my “new” brain. It functions better.

    This is excellent. The one ingredient most people are deficient in is magnesium. This does exactly what it says on the tin. Straight away you feel more alert and active. Sleep is much better too. In my case I slept deeper but shorter. When you wake up you are wide awake and fully alert within about 30seconds and without any aches and pains. Highly recommended.

    I have two thyroid disorders. I have more energy and clarity of thinking after taking this product for one week.

    I’ve noticed from my last purchase that caps are overfilled and it is definitely more than 144mg per capsule as the bottle say. I started to doubt if this is authentic so I will just purchase my next one to Mandimart and not in Amazon anymore.

    Magnesium Threonate is the best form of magnesium for mental health/neurological function as it can be absorbed into the brain. Hence many people find it the best form to help them sleep or with anxiety.

    Personally, I don’t notice any difference taking this form of magnesium, but I did have a recent micronutrient test that proved I had a good high level of magnesium, so they do work and absorb well. I will carry on taking a few times a week to top up my magnesium levels. Life Extension is a very high quality brand.

    These are fabulous! I have social anxiety and this
    supplement has allowed me to be around people
    in a crowded social scene, at least for a couple of hours.
    It also helps with thinking and concentration. But
    the main thing for me is getting past that wall of social
    anxiety. So nice to be around people again, even
    for just a little time.
