Magnesium L-Threonate | Support for Cognitive Health and Brain Function
Magtein® (magnesium L-threonate) is a unique, patented form of magnesium resulting from 10 years of research at MIT. It is the only form of magnesium shown to cross the blood-brain barrier, effectively increasing magnesium concentration in the brain.
Clinical applications of Magtein®:
• Supports healthy synaptic density and function
• Supports a healthy stress response, and a healthy mood
• Supports cognitive health, focus, and attention
Unlike other brain boosting supplements, which often overstimulate the brain, Magtein® works by nourishing the synapses with magnesium, which helps keep them healthy without overstimulation. The nourishing effects of Magtein® can help your brain think clearly and maintain resiliency.

Muy malo, no vine completo, además se demoró mucho más de lo que decía al momento de comprarlo. Solo aplazaban la fecha de entrega sin consultar cómo afectaba al cliente. Yo tuve que presentar el examen sin el libro, porque no llegó en la fecha que decía al comprarlo y después se cambió 3 veces la fecha, casi cumpliendo el mes.

All around helpful---worth the money!
Format: Paperback
This guide has been most helpful for all the folks I help prepare for the iTEP test! It gives insight into what each section of the test is looking for along with examples and great tips about actually TAKING the test. In the Writing and Speaking sections, it also gives sample scores and comments from the Master Grader which is very helpful too.

Comprehensive, clear and coherent!
Format: Paperback
The iTEP Practice Guide combines a no-nonsense approach to the specific iTEP tests and at the same time offers exercises that task the student with what they need to know. Exercises not only serve the purpose of scoring well, but the overall approach is communicative competence. We use the text in our group and one-to-one classes with very positive--and lasting--results.
