It Put Me On An Even Plane.
After 2 months of using this supplement my sleep has improved immensely. I wake up refreshed and recharged Jitters have subsided. And bathroom trips are on a schedule.

No more migraines
I have suffered migraines for years. It was so bad in December 2025 that I begged my neurologist for help. He suggested several things that I was unwilling to try due to the side effects. However, he recommended I try 400 mg daily of Magnesium L Threonate. January 2026, I started the taking it. The first month only 3 migraines for the whole month after years of 3-4 migraines a week. Its May 2026 and I have only had 3 more migraines this year. I highly recommend this product for migraine prevention.

The best Magtein I have tried thus far
I take double the dose because when I double the dose it improves my ability to pay attention and I am less distracted. Yes I have ADD but no longer take Adderall for it. Being 56 years old Magtein really improves my memory and restored it to like new by ten days of use. Shockingly It woke me up from a light sleep late evening as memories rushed in and I have been taking it ever since. I have been taking it 7 months now and over time it has slowly but surely improved my short term memory so that it also is nearly the same as before. I have seen slight improvements in working memory enough to be encouraged It may become an advancement from a historical standpoint. This is my second bottle by Teraputics. I was taking 2 bottles of NOW brand per month for my memory and concentration because it is the cheapest but when Amazon ran out Teraputics is the product I decided to try next. But I like this brand better as it seems more concentrated or I should probably say more bio-available so I decided to by it and pay the extra money over NOW brand. I just wish it were cheaper. I am hoping to ask them for a deal if I buy 20 bottles in advanced as it is a must have for me. With this second purchase they included a free bottle coupon and not a buy one get one free. Right now I am very happy to get the free bottle.
