Improve your brain function with Magtein® L-Threonate, proven to increase synaptic density which helps memory, attention and learning focus.  Methyl-Life® brings you Magtein® in its purest form, without a single additive, an odorless and tasteless powdered form of magnesium.  We’ve hand-picked this innovative and highly bioavailable version of magnesium designed to enhance brain function in four different ways:  1) attention  2) working memory (executive function)  3) long term memory and  4) short term (or episodic) memory.  Magtein® crosses the blood brain barrier and has shown stunning results in human as well as animal studies.  It is protected by 8 US & international patents.

Magtein® recently demonstrated remarkable results in a human clinical study on dementia & Alzheimer’s published in the Journal of Alzheimer’s Disease.   It showed a meaningful increase of memory-related functions in the brain which represented a 9 year age improvement when subjects supplemented with Magtein® (5).  The study revealed that less synaptic density actually means more memory loss, which is why the mechanism of action for Magtein® seems to be so critical.  Magtein® essentially makes more synapses for the brain to use.  Synaptic density improves recall functions in the brain.  The findings concluded that as long as the nutrient was present, cognition got better, however, when Magtein® was removed from the participants’ daily regimens, the synaptic density was reduced and the memory impairments returned.

The main side effects were a substantial reduction in stress and anxiety.  In an animal model, it was noteworthy to learn that Magtein® enhanced the control of fear-stress memory – the brain regions known to control stress and fear actually improved with the nutrient (prefrontal cortex/hippocampus) (3,4).  In a rat study Magtein® was also shown to increase the learning ability of young rats in addition to improving their working, short and long term memories (1,2).

Methyl-Life® is very excited to bring you this revolutionary new magnesium for your own cognitive enrichment!

Magtein® L Threonate Brain Magnesium Powder   120 grams   60 servings

Magtein® L Threonate Brain Magnesium Powder   120 grams   60 servings What is the right dosage for me?

Most studies have found that 2 grams per day is effective for improving brain health by increasing memory recall, attention and learning functions.  And instead of having to swallow 3 capsules today, we’ve produced a form of the nutrient that you can easily stir into a liquid (and that has absolutely no additives whatsoever, it’s just pure, 100% Magtein® only).

Magtein® L Threonate Brain Magnesium Powder   120 grams   60 servings Has Magtein® been proven effective?

Check out the published study in the Journal of Alzheimer’s Disease [Guosong, L., et al., Journal of Alzheimer’s Disease 49 (2016) 971–990].  There’s great science showing how this nutrient affected cognition and memory function equivalent to a 9 year age improvement.

15 reviews for Magtein® L-Threonate Brain Magnesium Powder – 120 grams – 60 servings

  1. Daniel J. Collins

    Exact same ingredients as another product I was having to go through my chiropractor to get. Helps me sleep and helps keep me calm. Love this form of magnesium and will not be without it.

  2. Heather J. McDaniel

    I love this form of Magnesium, I’ve been taking it for approximately a couple of months and can tell my magnesium deficiency is much better. I was having a lot of troubles that regular forms of magnesium were only “band-aiding” they were not helping with my low levels and I was still having major symptoms.

  3. Kenny D. John

    First encountered this formula with my doctor’s office, where they sell it under a naturalpathy RX ( traditional western medicine clinic). I’m pleased to find it on Amazon for slightly cheaper. BE CAREFUL TO GET THIS EXACT FORMULA – there are others out there without the same amount and type of Magnesium. This product is the real deal. It works way better than any form of Magnesium tablets. It works well for muscle pain, reducing migraines, reducing restless/jumpy legs, getting better quality sleep…so many positives. It is a pricey supplement, but this is one that is 100% worth it. I can’t recommend it enough.

  4. Jason D. Richards

    This is an excellent magnesium supplement, one I refuse to do without! The taste is great and the effects are fantastic. Since taking I’ve noticed that my brain fog has lifted and I can think more clearly and concentrate better on the task at hand. My evening dose relaxes me and gives me a deep restful and refreshing sleep.

  5. Mindy R. Mastrangelo

    Great product, I bought it for my kids and I see difference.They sleep better at night, are well rested in the morning, and I give it to them as part of vitD3 and K2 routine.They are happy and healthy!!! Highly recommended!

  6. Anna J. Kelly

    I am really impressed by this magnesium supplement. I have tried so many different herbs and vitamins to help me get some quality sleep, but nothing has made a lasting difference (especially now that I am going through peri-menopause). Since taking the Magtein® L-Threonate Brain Magnesium Powder, I noticed a significant difference in my ability to sleep. And it’s the one supplement in my cabinet that doesn’t taste horrible. I actually mix it with my other supplements to help mask their taste. I still have occasional restlessness, but nothing like before. As long as I take the NeuroMag before bed and take my adrenal supplements early enough in the day and get in a good workout, I get to sleep. That is a wonderful thing! Customer service was also terrific. I will definitely keep buying this one.

  7. Harrison G. Salisbury

    Been taking for 2 days. Before I was using the 300mg magnesium serving provided by the 2 pills made by Designs for Health Magnesium Buffered Chelate (from TRAACS Magnesium Bisglycinate chelate- buffered and magnesium oxide). Then I heard about the L-threonate form, and it’s cognitive enhancement abilities and depression/mood/anxiety/etc. so I wanted to try it. So far I feel like I had a much clearer mind, able to focus better, think faster, sleep better, and my blood pressure stays in normal range for once!

  8. William L. Wise

    I’m overall pleased with this product! I’m a pharmacist and wanted a product for myself that was shown to be effective and would be worth the money spent. I purchased this to test out the product for myself, as well as find a product I could recommend. I have since recommended this product to many of my patients with health issues like arthritis, pain issues, diabetes, high cholesterol, high blood pressure, bone weakness, and other health conditions where magnesium is shown to be vitally important yet deficient.

  9. Brandon A. Mounts

    I give this to my son who suffered a brain injury. It has noticeably improved his language so that he speaks intelligibly instead of using garbled speech. He likes the flavor. The one issue is that after a month of use, he started to become hyperactive after taking it so I stopped using it and his language has gone back to how it was before. I think I will try a lower dose next time and see how well he does. I was giving him a half-scoop twice a day.

  10. Matthew S. Welch

    I knew it was working, as this is the only version of Magnesium that penetrates the blood barrier, flooding the brain with good nutrients. I did acquire a mild headache, I took two gel advils, I layed in bed, and off to sleep I went, wait what? I went to sleep without all my rituals! I SLEPT LIKE A ROCK – I haven’t slept this well, this deep in nearly a year or more. My mind wasn’t doing its normal racing, my thoughts weren’t controlling me. I know the headache is my body which is off balance, being rebalanced, the headache did NOT cause me alarm, it was confirmation this is working.

  11. Jenn G. (verified owner)

    Love this stuff! Helps us sleep well and with remembering things.

  12. Amy Barnes (verified owner)

    I feel much better, Sleeping better and my BP has come down also.

  13. Anonymous (verified owner)

    Great product! It has really helped with depression!!

  14. Anonymous (verified owner)

    This product has basically ended depression for me!!! I have never had anything help be with life long on/off depression before. I have tried prescription drugs that either made it worse or only took the edge off. My son researched and found this after we learned about our genetic problems related to metabolism etc. I felt normal energy for the first time in years when I began taking the Methyl-Life products. So thankful to him and so thankful for this company!!!!! Life saver and life changing!!!!

  15. Jenn (verified owner)

    This also is a game changer for my son and I. We sleep like babies on it and notice improvement in his grades and for me I have a sharper mind.
