Magnesium L-Threonate for Memory & Learning

We all want to maintain a healthy, agile mind throughout our lives, but stress, toxins, diet and aging can all affect our cognitive functioning, mood and brain health.

Magtein from NOW Foods is a dietary supplement featuring a patented form of magnesium (Magnesium L-Threonate) that is designed to pass through the blood-brain barrier for improved magnesium levels in the brain, which may offer support for memory, cognitive function and learning.

About Magtein:

Brain magnesium levels may be associated with improved synaptic density and connections, which in turn may support improved memory, attention, learning ability, focus and mood.

However, not all forms of magnesium can bypass the blood-brain barrier. This supplement features magnesium L-threonate, which can pass through this barrier and may help support and maintain healthy neurons.


  • May support brain magnesium levels
  • May help support and maintain healthy neurons
  • May promote relaxed mood
  • May aid learning, attention and focus
  • May support overall cognitive function
  • May support healthy synapse density
  • May support short and long-term memory


  • Vegetarian & Vegan
  • GMP (Good Manufacturing Processes) Quality Assured
  • Made in the USA

Suggested Use for Magtein:

Magnesium is necessary for neurological health, but not all types of magnesium are able to get into the brain where they're needed for optimal brain function. Magtein may help you maintain your memory and a healthy mood while supporting learning ability. Order yours now!
