Magnesium Threonate Magtein®, 90 capsules

Activate your potential with Magnesium Threonate Magtein®: essential support for your brain, emotional balance, and mental performance!

Your brain is the engine behind every success! You use it for every decision, reaction, memory, and moment of focus. If you feel like it’s sometimes running in slow motion, that it’s hard to concentrate, or stress affects your clarity, it’s time for a natural upgrade: Magnesium Threonate Magtein®,  the magnesium that goes exactly where it’s needed.

Magnesium Threonate Magtein® is a premium, innovative food supplement created especially to support brain health and optimize mental capacity. It is the only form of magnesium scientifically proven to effectively cross the blood-brain barrier, increasing magnesium levels directly in the brain, essential for neuroplasticity, neuronal connectivity, and memory.

This supplement helps rebuild synaptic connections, improving cognitive function and reducing “mental fog” or psychological fatigue. Regular use leads to better mental clarity, increased focus, and improved memory.

In addition to enhancing cognitive function, magnesium threonate plays an important role in regulating deep sleep and the circadian rhythm, supporting nervous system regeneration during the night and protecting the brain from oxidative stress. By maintaining optimal magnesium levels in the central nervous system, it helps restore a healthy neurochemical balance, with positive effects on mood and overall vitality.

Magnesium Threonate Magtein® is not just another magnesium supplement, but an advanced solution for cognitive performance, neuronal protection, and long-term brain health. With a high bioavailability profile and proven efficacy, this supplement is the ideal partner for keeping your brain active — every single day.

Magtein®: next-generation magnesium threonate for the brain!

Magtein® Magnesium L-Threonate is a patented form of magnesium derived from threonic acid, renowned for its exceptional absorption and bioavailability. This unique formula efficiently crosses the blood-brain barrier, delivering magnesium directly to the brain. Once there, Magtein® helps maintain and improve synaptic connections between nerve cells, essential for effective signaling and mental health.

Magtein®, Scientifically Proven Effectiveness!

A double-blind, placebo-controlled study published in Nutrients evaluated the effects of a Magtein®-based formula on cognitive functions in 109 healthy adults aged 18 to 65. After 30 days of supplementation, participants who received Magtein® “showed significant improvements in all five subcategories of the Clinical Memory Test compared to the placebo group. Improvements were more pronounced in older participants” (C. Zhang et al., 2022)¹.

Animal and human studies show that magnesium L-threonate improves and maintains cognitive function, even in older individuals with previous signs of cognitive decline.

In animal studies, it was shown that “oral administration of magnesium L-threonate increases magnesium levels in cerebrospinal fluid by 54%, boosts synaptic density, and promotes NMDA receptor production in brain cells” (I. Slutsky et al., 2010)².

In addition, clinical trials report that Magtein® is well tolerated, with no significant side effects on physiological or biochemical parameters.

Magnesium Threonate, Essential Fuel for Well-Being!

Magnesium threonate is a unique form of magnesium, distinguished by its ability to cross the blood-brain barrier—an essential advantage over other forms of magnesium. It reaches the brain directly, where it increases magnesium levels, stimulating cognitive functions and optimizing memory and concentration processes.

By enhancing magnesium flow to the brain, magnesium threonate supports long-term neuronal health, reducing the risks associated with cognitive decline. It also significantly reduces anxiety and stress, playing a crucial role in regulating neurochemical balance and protecting neurons.

With higher bioavailability than other forms of magnesium, this supplement improves the brain’s metabolic functions, supporting intellectual performance during both high-concentration periods and mental recovery.

Key Benefits for the Brain:

• Improves memory and focus by increasing magnesium levels in the brain.
• Supports long-term cognitive health and helps prevent neuronal decline.
• Reduces anxiety and stress by stabilizing neurochemical balance.
• Superior absorption compared to other forms of magnesium, with fast, noticeable effects.
• Provides neuronal protection against stress and aging.

Magnesium threonate is the ideal choice for those seeking to boost cognitive performance and protect their brain from the negative effects of chronic stress and aging.

Magnesium Threonate: Quality Sleep for Active Minds!

Sleep isn’t just a break, it’s an essential process through which the brain recovers, clears toxins, and consolidates memories. Yet, stress, the fast pace of life, and digital overstimulation severely impact sleep quality. That’s where magnesium threonate comes in—the only form of magnesium scientifically proven to cross the blood-brain barrier and act directly on the brain.

Unlike other forms of magnesium, magnesium L-threonate (Magtein®) influences sleep through multiple synergistic mechanisms, supporting deep, uninterrupted rest and overnight cognitive regeneration:

• Increases magnesium levels in the brain, a mineral essential for calming neural activity and reducing synaptic hyperexcitability—a common cause of insomnia.
• Regulates GABA levels, the neurotransmitter responsible for relaxation and deep sleep—soothing the sympathetic nervous system (the “fight or flight” response).
• Lowers cortisol, the stress hormone which, if elevated at night, can prevent sleep onset and cause nighttime awakenings.
• Supports circadian rhythm synchronization, helping the brain enter deep (NREM) sleep faster and stay there long enough for full recovery.
• Reduces anxiety and chronic stress, common causes of sleep disorders.
• Improves neuroplasticity during sleep, when the brain consolidates daily information—essential for memory and learning.

A recent study with 80 adults aged 35–55 found that “magnesium threonate significantly improves sleep quality by increasing deep and REM sleep and supports mental clarity and elevated energy throughout the day. Participants reported fewer nighttime awakenings and improved mood, and the supplement was well tolerated with no notable adverse effects” (A. Hausenblas et al., 2024)³.
