Source Naturals Magtein Magnesium L- Theronate 90 cap.

The Brain-Optimized Magnesium

Source Naturals Magtein features magnesium L-threonate, a breakthrough form of magnesium specifically designed to support cognitive function, memory, and brain health. Unlike other forms of magnesium, Magtein has been shown in research to effectively cross the blood-brain barrier, elevating magnesium levels in the brain to support synaptic density, neuroplasticity, and overall cognitive performance.

Breakthrough Research for Brain Health

Magnesium L-threonate was developed by a team of neuroscientists at MIT and is the only form of magnesium proven in animal studies to significantly increase magnesium concentrations in the brain. This is critical because magnesium plays essential roles in brain function: it supports the formation and strengthening of synaptic connections between neurons, promotes neuroplasticity—the brain's ability to adapt and form new neural pathways, helps regulate neurotransmitter activity for balanced mood and cognition, supports healthy sleep patterns and circadian rhythm, and protects brain cells from oxidative stress and age-related decline. Clinical research suggests that maintaining optimal brain magnesium levels may support memory formation and recall, learning capacity, attention and focus, cognitive processing speed, and overall mental clarity.

Beyond Brain Health: Total Body Support

While Magtein is uniquely effective for brain health, it also provides the essential benefits of magnesium throughout the body. Magnesium supports healthy muscle and nerve function, helps maintain cardiovascular health and normal blood pressure already within normal range, supports bone density and skeletal health, promotes healthy blood sugar metabolism, and helps the body manage stress and maintain calm. This makes Magtein an excellent choice for those seeking comprehensive magnesium support with enhanced cognitive benefits.
