The questions you ask are well defined in that post. I chose Magtein manufactured b Magceutics because the recommended dose is 2 capsules daily. Other brands specify 3 capsules daily, and that is inconvenient and impractical for me. I decided to pay a little more for the original magL-threonate for that reason. This original brand contains 73.5 mg per capsule of Magnesium (from 2042 mg of Magnesium L-Threonate). My choice was one of dosage convenience (2 caps per day). I am still quite pleased with MgT. My physician also approves MgT. I hope all goes well for you! **Q: Does anyone know if the contents of these capsules are tasteless? My mom has issues with pill swallowing so I have to open the pills in her food.** A: I am using this product for a family member who is recovering from brain trauma after an accident. He can't swallow the pills, so I put the powder into orange juice for him. He says he can't taste it at all. If I add two pills to about 4 ounces of juice, he says it's chalky. **Q: Where can I get a copy of the pre-clinical studies cited?** A: Here's a couple: I haven't actually read these articles. And, I'm not qualified to comment on them in any case. That said, the compound continues to work for me. https://www.cell.com/neuron/fulltext/S0896-6273(09)01044-7 http://file.scirp.org/pdf/Health_2016052715242163.pdf ## Customer Reviews ### ⭐⭐⭐⭐⭐ Relaxing. Affordable. Very Potent. Clean. *by on Reviewed in the United States January 16, 2018* Updated: 19/02/2018Been using this for some time now, there is a noticeable relaxing effect (initially it made me anxious but by week one of regular use it relaxed instead) this seems to increase blood flow to the brain rather dramatically, but the effect is quite nice when combined with say green tea or real matcha you become very relaxed and very alert (most likely more green tea components make it to your brain).This is likely more like an 'enabling' supplement. However I have found ionic/liquid magnesium to have a MUCH more dramatic effect on memory and over all body relaxation IF you are getting enough vitamin D and C along side it. As 400 doses of magnesium chloride costs around $9 USD and you only get about 3 months out of this container (or 1-2 months if you supplement a higher dosage) and the rest of the body desperately needs more magnesium than the brain.... just taking more magnesium in the diet has the same effect (i.e. 600 mg a day instead of 460 mg). But when not taking enough: MORE magnesium makes it to my brain with this (very pronounced effect after adaptation period) product!Absolutely wonderful and no fillers! I am terribly allergic to certain fillers and highly active 'inactive' and 'stabalizers' ingredients in supplements so these are heavenly for getting magnesium to my brain neurons (heavy mitochondrial damage in my brain, and gilial cell starvation issues with BBB due to complicated nutrient processing/absorption differences).3 things to note:Very potent, at 2 capsules a day you definitely feel dramatic changes in neuronal firing/signaling (less likely to depolarize mid synapse chain).Because of the previous feelings of anxiety/dread can be greatly enhanced as synaptic firing is less likely to 'stop' on demand (biofeedback) so if there IS actually something to be afraid of (such as snow 'quietly' about to collapse your roof, or a wild animal/human prowling around the general area with hostile/invasive/subverse intent) the feelings will be unable to be suppressed or 'let go' of until the magnesium, D and C is fully metabolized (up to several hours depending on what you are doing) so I don't really recommend you take this to 'relax' from anxiety related stress or tension.Conversely to the above when the environment is safe and tranquil these help you relax quite more fully than say, deep meditation can alone, and you don't even need to mediate for a solid relaxation. It also aids general relaxation regardless of the previous too by relaxing many major muscle groups and excess tension (I recommend laying down on firm surfaces as your spine will relax too, and it could easily deform if you are laying or moving incorrectly!), though all magnesium seems to have this general effect. ### ⭐⭐⭐⭐⭐ Actually works for me with a bonus: no more CRAMPS! *by on Reviewed in the United States April 7, 2016* I started taking this because I'm researching Nootropic stacks and it did come recommended by a few fitness enthusiasts. I was wary of the association with MIT (I thought it may be a marketing ploy.) and I've been burned by so many supplements that don't do anything. After taking it a few weeks I figured I'd write a review about it being okay, however, it has a bonus effect I didn't consider as a possibility. It has stopped my leg and foot cramps!It didn't matter what shoes I wore, how much water I drink every day, or which magnesium supplement I took because the cramps stopped me in my tracks. I took this for two weeks with one capsule twice a day and cramps began to slow and then stop. FINALLY! I took up to 2 grams of some supplements by choking down 3 - 4 of those 500 mg horse pills a day, hoping they'd at least decrease the cramps. They had little, if any effect.I have low blood pressure and horrible muscle cramps but that's it. I'm not a diabetic, a vegan, vegetarian, have no bleeding disorders. Not all supplements are manufactured equally and I'm really surprised with how well this works when considering all the other brands that didn't.Since this is also part of my Nootropic stack I wanted to wait and see if anything was happening or if it's the dreaded placebo effect. I've never benefited from the placebo effect since taking a whole bottle of other brands only to have my leg seize up and twitch during a meeting. During the first week I started taking Magtein I had just ONE leg cramp and a minor foot cramp. In my experience I've had up to seven cramps just in my calf per day and four foot cramps. I even wake up cramping in my legs and feet then deal with soreness that doesn't want to go away. The two cramps I had that week lasted less than a minute and I haven't had a single cramp since then. I stretch and go for walks and runs with no cramps to slow me down. I can sit and work at my computer, stand, and basically do everything without waiting for a cramp to stop me. If that doesn't make you happy I don't know what will.My actual benefits:1. Increase in mental stamina and focus for complex tasks.2. Elimination of mental fog.3. Full night of rest every night.4. No more cramps!5. * Dose can be changed.* By taking two capsules a day you get 36% of your daily recommended allowance. If you want to take a bit more you can. ### ⭐⭐⭐⭐⭐ Does What It's Supposed to Do Without Any of the Negative Side Effects of Other Mg Supplements *by on Reviewed in the United States May 24, 2016* Having tried pretty much most forms of magnesium supplements out there, from the chelated kinds to the downright terrible ones (looking at you, Magnesium Oxide), I can say with some certainty that this product just....works.If you're looking into magnesium for it purported anxiolytic and relaxation benefits, this supplement is definitely something to look into. Many various forms of Mg have low bioavailability or cause negative GI tract issues that make them a pain to take. This form of magnesium does not appear to have any of those issues, and absolutely has positive effects on mental well being and cognition.I'm a long time insomniac; while I haven't particularly struggled with serious anxiety disorders, I do regularly experience what you can call a debilitating "antsiness" that has frequently made it difficult to relax or fall asleep. This supplement almost immediately helped me tackle the issue. Within the first few days of taking the supplement, I've experienced drastically improved sleep quality and speed of falling asleep, and wake up much more ready to start my day.I take 1 in the morning, 1 in the afternoon, as directed by the label. It helps tone down the negative, jittery side effects of prescription stimulants and caffeine to the point where I effectively get to reap the benefits of both substances. It's been fantastic both in that regard and helping me relax and fall asleep after a long, hectic day of work.If you've read and heard about the positive effects of magnesium and have been trying to get them from other forms of the supplement, but have experienced no benefits and/or have had to deal with associated GI issues, I highly recommend giving this product a shot. It seems pretty gentle on your system, and its benefits are apparent from the first few times you take it.I have been taking this primarily for brain health/benefits; I haven't looked too much into the physical benefits it might be giving me, such as lowering blood pressure and relieving cramps (things magnesium is also known to do). I plan on taking it for a few more months in order to assess long term benefits, but short turn, its definitely been a fantastic product and I highly recommend trying it if the above applies to you. ## Frequently Bought Together - Magtein - Magnesium L-Threonate Supplement, Memory, Focus, Sleep & Brain Health Formula for Men & Women, Cognitive Support for Adults, Clinically Researched - 60 Veg Capsules - THORNE Glycine - Amino Acid Support for Relaxation, Detoxification, and Muscle Function* - 250 Capsules - Pure Encapsulations Magnesium (Glycinate) - Supplement to Support Stress Relief, Sleep, Heart Health, Nerves, Muscles, and Metabolism* - with Magnesium Glycinate - 90 Capsules --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/17142552-magtein-magnesium-l-threonate-supplement-memory-focus-sleep-and-brain](https://www.desertcart.com.ar/products/17142552-magtein-magnesium-l-threonate-supplement-memory-focus-sleep-and-brain) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-08-22*
