Magtein Magnesium L-Threonate Capsules

What are Magtein Magnesium L Threonate Capsules?

Magnesium is an essential cofactor for more than 300 enzymes involved in biosynthesis processes and energy metabolism. It plays an important role in many of the brain's functions. Only recently, a unique compound called Magtein was discovered by a group of scientists from MIT, including a Nobel Prize laureate.

Magnesium has been implicated in many of the brain functions. However, most magnesium compounds have low brain bioavailability and severe gastrointestinal side effects. Magtein is the only magnesium compound that has been shown to effectively raise the brain's magnesium levels, which leads to enhanced learning abilities, improved working memory, and better short and long-term memory in both young and aged animals.*

Magtein currently has several published studies in highly regarded journals reporting its mechanism of action and benefits to cognitive function.*

Magtein Benefits and Uses

Various studies have shown that Magnesium plays an important role in regulating memory formation, mood and protecting the brain from various stressors. However, various other studies have also shown that Magnesium supplements, especially forms such as Magnesium Oxide, have a fairly hard time elevating brain levels of Magnesium to statistically significant levels, which is why Magnesium L-Threonate is currently the only form of Magnesium that will produce significant effects on overall cognition.

When Magnesium reaches the brain, it mainly interacts with the NMDA receptors, which play a key role in the formation of memories. The NMDA receptor contains a specialized site within the receptor to which Magnesium can bind. When Magnesium binds to this site, it blocks the receptor, which prevents the receptor from activating. This protects the brain from the negative effects of over-activation of the NMDA receptor. NMDA receptor activation, however, is also vital for the formation of memories and this is where Magnesium has a very unique effect. It increases the amount of NMDA receptors in the brain, whilst blocking background activation, which means that when the NMDA receptors get activated during memory formation, there will be a much stronger NMDA receptor response, leading to deeper and faster encoding of memories.

    I love you noot depot <3

    F*ck the price tag on it, nothing is more important than a full night deep sleep and that is exactly what this Mg supplement does for me. I'm currently on pain meds and they're notorious for waking you up in the middle of the night. Many clinical studies have been done to combat these sleep disturbances with nearly all of them having no significant improvement on the patients sleep quality. I've tried a dozen different supplements that did nothing for my sleep disturbances before I found this. I am now having THE BEST SLEEP EVER.

    Incredible for relaxation

    Out of the hundreds of supplements I've read about and tried, this and Omega 3 are the only supplements I think *everyone* should take. The range of benefits shown in studies is incredible, and the body won't absorb more magnesium than it needs. Like Omega 3, I've been convinced by research that this is really good for me long-term, and that's good enough a reason to take it. But Magtein also has very noticeable immediate effects. It's hard to put the right words on the effects, but I guess the closest description is that it reduces "noise", both mental and physical. Physical noise being like restlessness kind of. Reducing mental noise is kind of comparable to moving toward a state of flow. You could also say it increases focus, except that it does so indirectly by removing noise, not by e.g. increasing alertness. The effects remain after daily use for 1+ years, and I really appreciate ND offering this in huge sizes.

    Can’t go without it

    I take 2 of these every morning and have no plans to stop. The price made me wonder if I really needed it.. Until I ran out and felt sluggish without it. It definitely provides some morning clarity and helps keep motivated through the workday. This one stays on hand for me and is a must. I absolutely love this company, the fast shipping and overall the quality of everything I order.

    I am a hardcore believer that just about anyone can benefit from a magnesium supplement as long as it has stellar bioavailability. Up until I tried this, I was regularly using Glycinate form (from a different vendor). I decided to switch it up and give this a try, and I'll never go back. I have less brain fog and can get through the day, and the PM dose helps sleep just as much, if not more, than Glycinate did. I notice a big difference on days I don't take this.

    Amazing for Sleep

    Listen, if you have sleeping issues please try this. Insomnia runs in my family (my mother is an insomniac) & unfortunately that trait was expressed through me as well. If you’re someone who has mild to severe sleeping issues I would recommend this product. My personal experience: I had trouble both falling & staying asleep basically my entire adult and adolescent life..even in my youth. Over the past 2 months+ I have used the powder form of this product and have now been using these capsules, both demonstrating the same effect. Long story short, when consistently following the directions and going to bed at the same time every evening, I fall right to sleep in 15-30mins which is a vast improvement from my typical 2-3hrs. I still have trouble with waking up during the night but I typically fall right back asleep within minutes! Obviously lifestyle will affect your situation, but if you’re doing everything else right & you still have sleeping issues...seriously try this’s somewhat sedative the first few times you try it but nothing alarming at all! I don’t know that I’ll ever stop taking this. It truly is increíble for sleep and I haven’t experienced any noticeable side effects apart the initial sedative effect and the fact that I actually feel sleepy/tired at night now!

    It’s a shame that a company like this has to use fillers and additives. Silicon dioxide is not a good product to be putting into capsules. I’m very sensitive to the nasty ingredients that goes into these capsules. It’s a shame cause I’d give it a better rating if it wasn’t for the fillers and binders in this ND Admin: silicon dioxide is not a filler. It's a flow agent. It is used to allow the Magtein to flow over encapsulation machines properly. It's in 99% of the Magtein out there, whether they list it on the label or not. You can't get the Magtein powder to flow on the machines without it. Many brands just leave it off the label. However, it is being used most of the time. We are talking a very small amount, though. It's half a percent, or about 3.4mg per capsule. That's hundreds of times less than you get in everyday things like flour, baking powder, sugar, table salt, protein powder, etc.

    My Brain Feels Fitter

    I take this with Piracetam and can definitely feel the difference with/without. Magtein truly clears my brain fog and helps me access details I generally can't quite get to inside my noggin Remembering to take the extra 2 before bedtime gets a little tricky, but nothing that Siri can't take care of for me (lol). I've tried other magnesium supplements and had to stop as they made my tummy do flips and end up on the loo longer than expected. Not with Magtein! A true godsend.

    Yeah so have you ever used Fancy Fance magnesium?

    It's pretty lit but sucrosomial or even glycinate are ok too when you don't require the MOST FANCY kind :)

    Best clean laser focus

    I don’t think anything can beat this mag in terms of clean clarity and focus. This is a must for any stack. The only one that crosses the blood brain barrier. This is one of the things that allows me study over 5 hours a day.
