Magnesium L Threonate, Magtein™, Brain Supplement for Memory, Focus, Sleep and Cognitive Support, High Absorption Magnesium L-Threonate, Non-GMO, No Laxative Effect – 2000 mg, 100 Vegan Capsules

Great product! I'm a deep skeptic of all the memory cures being marketed but the magnesium l-threonine actually works! And immediately! After one pill I dreamt of an incident in high school and I never dream about such stuff. Continual use has greatly increased my ability to recall names and I can now picture and name all the states of the U..A.!No side effects yet though it has been reported to sometimes cause nausea and cramping.Works great!

Does the job and works as advertised.

Effective

Great product! It really helps the quality of my sleep! Most people in the world are deficient in magnesium. I've tried other magnesium supplements. They are not all the same!

EN ORDEN!!!

Prime handed off this delivery to USPS, who claimed it was "undeliverable" (at an address they've delivered to for a long time). I then had to find it and go fetch it myself a couple days later at the PO.

Excelente producto

The rating is arbitrary. I experienced no obvious results from the use of this item, so I can't really offer any meaningful feedback. I have tried other brands and forms and have never received any particular benefit that I could discern.
