Jarrow FormulasMagnesium L-Threonate, MagMind Magtein Brain Supplements for Memory Support, 90 Veggie Capsules, Up to a 30 Day Supply

I've always trusted Jarrow Formulations for their quality and reliability, and their Magtein magnesium supplement continues to deliver on that reputation. Magtein itself is fantastic—it noticeably helps me unwind at night, ease away the stress of the day, and promotes restful sleep. I've found it particularly effective for calming my mind after too much caffeine or a stressful day, as it reduces glutamate overstimulation, which can leave me feeling anxious or wired.Unlike some other brands, Jarrow thoughtfully includes a moisture-absorbing packet inside, helping preserve freshness and potency. Pricing is quite decent considering the brand's reputation and the proven quality of the product.Overall, if you're seeking reliable Magtein at a fair price from a trusted brand, Jarrow Formulations won't disappoint. Highly recommended for anyone who wants a gentle yet effective way to support calmness and better sleep quality.

I have been using Jarrow Formula supplements for a number of years, especially the Vitamin B12 - methylcobalamin and Vitamin K2 - MK7 supplements. I have been impressed with their continuing development of new *effective* products at a great price point.My husband and I have been taking approximately a gram a day of supplement Magnesium (cheaper products) for almost 5 years now. In that time we have cured his former type 2 diabetes (after almost a 2 decade battle with medicated fasting BGs in the 500s at one point!) and we have almost completely reversed his hypertension of many years as well has have turned his end stage Severe Congestive Heart Failure around so he's relatively free of symptoms. I credit not only the magnesium, but also high doses of Vitamin D (ALWAYS taken with magnesium and fish oil!!), a whole foods source multi, the Sinatra Protocols for supplements as found in the back of The Sinatra Solution: Metabolic Cardiology and a number of minerals especially trace minerals as found in Liqumins ConcenTrace Trace Mineral Drops, Low Sodium, 8-Ounce Bottle.I was looking into research on magnesium and the brain when I ran into the MIT study published in 2010 showing magnesium L-threonate is the only form of magnesium to cross the blood-brain barrier and showed observable improvements in cognitive measures. Interesting. So we bought a bottle at our local neighborhood nutrition shop after a discussion with the owner, a couple I have come to trust during our many battles with the medical establishment.Jarrow Formulas of magnesium L-threonate as Magmind is a very cost-effective source. To further economize we are still taking our regular magnesium supplement 3 times a day (750 mg) then taking this form of magnesium as part of our bed time routine (replacing the 4th magnesium of the day). I am genuinely impressed. Our sleep has improved yet another notch, which is saying something since the 5 years of magnesium supplementation meant we already had really good sleep quality. What I have noticed is that after multiple head trauma injuries (including a serious concussion earlier this year) my previously very high level of spatial relations was slipping. Now with Jarrow I feel I'm getting that edge back. I am very impressed. I will update again with further results after we've been taking this formula longer.2015 UPDATE - in the years since we first tried MagMind I've referred hundreds of people to try this quality supplement with great results. We've since learned to couple magnesium with taurine for even greater results. Taurine is VERY well documented to improve the fluidity of electrolytes within the cells including within the brain.NOVEMBER 2016 UPDATE:Well, here we are 4 years later. We still personally use and recommend MagMind. What we discovered though, since he was put on Armour Thyroid by our primary care he no longer seems to be "leaking" magnesium hence we've cut magnesium supplementation waaayy back. Plus we soak in epsom salts far more. Magnesium is still vital however we're no longer "taking a gram a day."

Great for sleepy time. Be sure to cycle on and off to give yourself a little break. A staple of my night-time stack. I don't take them during the day, only a couple an hour or so before bed. Been an MG fan for a while now. Wake up feeling good and not groggy. Works great for me. Ymmv.

I take magnesium near-daily and have for some time due to my diet. Mostly it's glycinate, though sometimes I'll take some citrate. This is my first experiment with l-threonate.Before I get into this, I am not taking this as directed. I take 2 capsules during the day and usually take a different type of magnesium toward evening. I have about 40 capsules left, so I've taken a bit more than half the bottle so far.Supposedly magnesium l-threonate may give you brain benefits over other types of magnesium. If it does, I'm not sure. It seems to have the same, general magnesium benefits for relaxation, sleep, muscles and nerves, but I don't notice any clear indication that my brain is working better: I'm thinking clearer, faster or am sharper mentally. This could be happening to a small degree, but other changes I've made could lead to this as well, so the waters are muddy there.I'm going to cycle back to magnesium glycinate after I'm done with this bottle, or maybe open up my magnesium optimizer (also by Jarrow -- magnesium malate, b6, potassium and taurine), then come back to this again. See if there's any noticeable difference in my mental capabilities or focus. If I seem to see an association, I'll update this.I like the brand. I've used their Magnesium Optimizer before and was pleased with that (bought another bottle), their fulvic acid / shilajit -- that seemed to work. I'm a fan. This magnesium is more expensive than other types, but at present I'm not sure that extra cost is worth it over a different type of magnesium.
