RetzlerRx® Magnesium L-Threonate | Brain, Sleep & Cognitive Support | Magtein®

Advanced brain magnesium support with Magtein® for cognitive function, memory, mood balance, and healthy sleep-wake cycle support.*

Part of the RetzlerRx® physician-formulated longevity supplement system.

RetzlerRx® Magnesium L-Threonate is an advanced magnesium formula designed to support brain health, cognitive function, mental focus, mood balance, and a healthy sleep-wake cycle.* Magnesium is one of the most important minerals in human physiology, serving as a cofactor in more than 300 enzymatic reactions throughout the body.

Magnesium status can be influenced by aging, exercise demands, diet quality, medications, and certain health conditions. Because magnesium plays essential roles in the nervous system, adequate intake is especially important for individuals seeking support for cognitive resilience, sleep quality, and overall neurological function.*

Magnesium is involved in several key processes related to brain health, including support for neurotransmitter synthesis, receptor modulation, and maintenance of the blood-brain barrier. However, magnesium transport into the brain is tightly regulated, which is one reason specialized forms of magnesium have drawn attention in cognitive health research.

Featuring Magtein®, a patented form of magnesium L-threonate, this formula is designed to support magnesium availability in the brain. Research has associated intraneuronal magnesium with support for neuroplasticity, mental clarity, memory, and healthy brain aging.* This formula is designed for individuals looking to support cognitive performance, balanced mood, and restorative daily rhythms as part of a broader longevity and wellness plan.*

RetzlerRx® Magnesium L-Threonate may also help support calmness, occasional stress resilience, and overall quality of life by promoting healthy neurological function and sleep-wake balance.*

Because cognitive health, sleep quality, inflammatory balance, and metabolic health are interconnected within longevity medicine, magnesium status can influence multiple longevity pathways including nervous system function, metabolic signaling, and recovery physiology.*

Suggested Use
