Description

Why you'll love Magtein® Magnesium L-Threonate

Feel sharper and more focused with Magtein® Magnesium L-Threonate. This clinically studied form of magnesium supports brain health by helping you think clearly, remember details, and stay mentally engaged throughout your day. Magtein is designed to support the cognitive health you rely on every day.*

  • Supports memory so you can recall information more easily*
  • Helps you maintain focus and concentration*
  • Supports clear thinking and decision-making*
  • May support healthy connections between brain cells (synapses)*

The Science Inside

  • How It Works: Magtein® is a special form of magnesium designed to cross the blood-brain barrier more easily, allowing it to reach brain cells more effectively. Once there, it can support healthy brain signaling and cognitive function. Magnesium is also critical for mitochondrial function, the energy "engines" inside every cell, including brain and nerve cells. By helping cells produce energy more efficiently, it supports working memory, focus, and overall cognitive performance.*
  • Key Ingredient: Each serving (3 capsules) provides 2 g Magtein® (magnesium L-threonate), delivering 147 mg elemental magnesium (35% Daily Value). This form was developed specifically for bioavailability and brain health.*

What makes Magtein® Magnesium L-Threonate different?

  • Backed by Research: Features a form of magnesium shown in research to support cognitive performance and mental sharpness.*
  • Brain-Health Focused: Unlike magnesium glycinate, which supports muscle relaxation and sleep, Magtein® is specifically formulated to support your brain's health and cognitive function.*
  • Clinical Results: Clinical studies show significant improvements in thinking and memory.*

^In a randomized, double-blind, placebo-controlled trial, Magtein® supplementation was associated with a statistically significant improvement in modeled cognitive age, corresponding to an estimated 7.5-year difference versus placebo, in healthy individuals age 18-45.

What is cognitive aging?

Cognitive aging describes changes in cognitive performance over time, including memory, processing speed, and attention. An estimated cognitive age is a modeled performance score that compares cognitive function to population norms, reflecting performance outcomes rather than biological age.
