High quality magnesium supplement
Have been taking this high quality magnesium for a few years. It really helps with sore muscles and to aid in a better nights sleep. I also take for some other medical issues and it helps immensely. The combination of different types is convenient. Highly recommend.

Game charger for brain fog!
I’ve tried various forms of magnesium, but Magtein (Magnesium L-Threonate) is the only one that actually clears my morning brain fog. Unlike other types that mainly help with digestion or muscle cramps, this feels like it’s actually "upgrading" my focus. What I Noticed: • Mental Clarity: I feel sharper during work meetings and less "scattered." • Better Sleep: It helps me drift off without that heavy, groggy feeling the next day. • Zero Issues: No stomach upset, which is a huge plus compared to Magnesium Citrate. It’s definitely more expensive than standard magnesium, but for the cognitive boost, it’s worth every penny. If you struggle with focus or memory, give this specific form a shot.

Dial into Feeling Better Again Already!
This MagTech Magnesium L-Threonate blend works extremely well for better rest, patience & focus extension and calming of stress. I'm extremely pleased that each capsule contains about 133.33 mg of the product. This fact allows me to tailor my dosage to account for weight-based dosing & controlled system introduction to reach my optimal dose with minimal side effects. It was shocking to realize that so many suffer from a mineral deficiency that has such far reaching effects on their quality of life and this product is (so far) quite effective at restoring many of the skills & capabilities that had slowly dwindled away over time. I highly recommend slowly increasing your dosage over first few days to avoid system shock. It does seem to have a laxative effect, which is the only negative side effect that I've experienced (but could be a beneficial one for some). I'm convinced I would have immediately stopped taking it and given a poor rating to this product had I taken the full recommended dose from the get go. It's also reassuring to see that it is produced in the USA by an full product component disclosing facility. If you are trying to avoid prescribed Rx to alleviate certain symptoms, this is a worthy nutritional supplement that may likely fill your needs to naturally gain & improve control over undesirable condition symptoms. I'll continue to take it as long as it continues to give good results. This rating is based on just 2 weeks of product use and my daily dose is a fraction of the recommended daily doses. I did not received any free product, nor or any compensation or incentives to provide this review.

This product helps me sleep better.
This is a good product for me! I take one capsule at night to help me calm down and prepare for a night of good sleep. My husband and I both feel that it does help us to sleep better with less time spent awake during the night when we want to be sleeping. I was happy to find Magtein Magnesium available on Amazon because I could not find it locally to purchase. It has the magnesium formula I was looking for.

This stopped leg cramps for me
I am 78 years old and had random leg cramps for some years in the evening. Since I started taking this, I almost never have them anymore, and if I do, they’re very short term and very light. Mostly I never have them at all. I’m not under any illusion; they will not work for everybody, but they did work for me and I’m pretty grateful. Obviously each one of you is going to find out for yourself, and it may be worth a try.

Authentic, clean ingredients & it works
On a journey this year to improve my health: weight, cognitive function, clean eating, proper nutrition and better sleep. I’ve spent a lot of time devoting myself to research on one specific nutrient at a time and recently that study was on Magnesium. I like that this product has ingredients that suit my vegan lifestyle. I like that it has the three forms of Magnesium I am most interested in. The price is right and the shipping is fast. The pills are large but smooth, rounded and easy to swallow. And the best part - I noticed a difference the first night I took one. At night I am better able to calm my racing thoughts and physical discomfort. As someone with sleep apnea and severe insomnia with a completely broken circadian rhythm, this magnesium has eased me into sleep for 4 nights in a row now. It’s not a harsh knock out but a smooth calm and comfort. I actually feel tired for once and am getting 7-8 hours of sleep rather than 4-6 hours. Because my sleep is improved and because this magnesium crosses the blood brain barrier and helps with mood and cognitive sharpness, I feel on top of the world. I have energy, I’m thinking and speaking more clearly and I feel a sense of joy all day. These benefits aren’t forced by the magnesium - they are allowed to surface due to the direct benefits and sleep improvements. Great company and great product. I plan to setup a subscription after my first bottle is finished. I also suggest looking into Vitamin D3, K2mk7 and B Complex if you are vegan.
