Overview

Magtein is a magnesium L-threonate supplement positioned around memory, focus, sleep and brain health, packaged as 60 veggie capsules. It is kosher and vegetarian, aimed at adults wanting a magnesium form associated with cognitive support.

Magnesium L-threonate is a specific form of magnesium developed for its ability to cross into the brain more readily than common forms like magnesium oxide or citrate, which is why it is marketed here around memory and focus rather than general mineral supplementation. The title notes it is clinically researched, though the listing data does not specify which studies, so treat that as a brand claim to verify rather than an established fact.

  • Magnesium L-threonate formula
  • Kosher and vegetarian capsules
  • 60 count bottle
  • Positioned for memory, focus and sleep

Who it's for

Fits adults specifically looking for a magnesium form tied to cognitive and sleep support rather than a general-purpose magnesium supplement. Not the right pick for someone who just wants an inexpensive, high-dose magnesium for muscle or digestive purposes.
