Magnesium Threonate. Seems like it’s specifically meant for cognitive enhancement rather than magnesium deficiency like other forms.

The magnesium l-threonate is better able to pass the blood brain barrier as opposed to other magnesium sources. There are some interesting studies on PubMed around it being helpful for Parkinsons, alcohol related issues, and even short term memory in chronic pain sufferers (some are non-human studies).

Magnesium L-Threonate, also known as “Magtein”

I think it needs a different notation. Could be easily confused with Mg Taurate.
