Sports ResearchMagtein Magnesium L-Threonate Capsules - Magnesium Supplement for Memory, Focus & Cognition - Magnesium L Threonate Supports Brain Health, Sleep & Mood - 2000mg, 90 Capsules for Adults

This is my go-to for Magtein now. I can feel it help to melt the stress away. Improves my focus and recall and the price is right.

Good supplement and works to raise magnesium levels. No stomach discomfort.

This product works very well, with no side effects. The effects can be felt from the first day, improving sleep quality by keeping you in REM sleep longer, and making you dream more. I measure my sleep with a Galaxy Watch.For those who experience headaches or drowsiness during the day, simply reduce the dosage. The label recommends 3 pills, but you can take 2 or even 1 instead, and those side effects should disappear. To avoid feeling sleepy the next day, take it between 6 and 7 p.m., because if you take it too late at night, you might still feel the effects in the morning—even if you feel well-rested.

Great product! I’ve reordered many times.

Bought this to put me to sleep and it does exactly that.

After hearing of this being recommended by a few people that I follow including Andrew Huberman adding it to his sleep regimen, I figured I’d look into Magtein a bit more. The medical studies that I could find suggested decent support that it has some brain benefits, though there was less supporting research for sleep benefits. I decided it was worth a try, and ended up popping a few before bed.Unfortunately, it actually seemed to have a slightly adverse impact on my sleep. It could very well have been a placebo effect, but I took it for a week before bed and seemed to notice increased blood flow to my head, which made it more difficult for me to fall asleep. I tracked about half an hour of less average sleep during the week that I was taking it (with both Oura Ring and Apple Watch), so I decided to stop taking it in the evening.Having already bought it and being unable to return it, I switched to taking it at lunch with a coffee, and that seems to be working well. My sleep is no longer being negatively impacted, though I’m not sure if I’m experiencing any positive benefits from it. There’s a fair amount of research behind the positive benefits of Magnesium and Magtein, so I’ll definitely finish off the bottle, though I’ll have to assess at that point if I want to order another or not.The pills themselves are a decent size but not difficult to swallow. It does have a bit of a synthetic taste, but it’s not overwhelming and seems fine. Sports Research as a supplement company is well known and trusted, and I buy other supplements from them and have been pleased overall with the quality.

Easy to swallow, Decent price with subscription. Quality tested

Big fan of this company. Great quality supplements and I am always swayed by the sleek design. Really happy with the way it works!
