Product Description

Magnesium L-Threonate is an advanced magnesium compound developed for high bioavailability and enhanced absorption efficiency. Compared with traditional magnesium salts, Magnesium L-Threonate is especially valued for its ability to effectively cross the blood-brain barrier, making it widely used in brain health, cognitive support, memory enhancement, sleep support, and stress management formulations.

Jiangsu Khonor Chemicals Co., Limited supplies premium quality Magnesium L-Threonate powder suitable for dietary supplements, capsules, tablets, sachets, and functional nutrition products worldwide.

Typical Specification

Functional Benefits

Cognitive Function Support

Magnesium L-Threonate is widely studied for supporting memory, concentration, learning ability, and overall cognitive performance.

Brain Health Enhancement

Due to its superior brain bioavailability, it helps maintain healthy neuronal communication and synaptic plasticity.

Sleep Quality Improvement

Magnesium participates in neurotransmitter regulation and relaxation pathways, which may help improve sleep quality and reduce nighttime stress.

Stress and Mood Support

It helps regulate nervous system balance and may assist in reducing mental fatigue and stress-related discomfort.

Muscle and Nerve Function

Like other magnesium sources, it contributes to normal muscle contraction, nerve transmission, and electrolyte balance.

Working Mechanism

Magnesium L-Threonate is formed by combining magnesium with L-threonic acid, a metabolite of vitamin C. The unique molecular structure improves magnesium transport and absorption efficiency, especially within brain tissues.

After absorption:

• Magnesium ions support neurotransmitter activity and neuronal signaling.

• L-threonate enhances magnesium penetration across the blood-brain barrier.

• Increased brain magnesium concentration may help improve synaptic density and neural communication efficiency.

This mechanism makes Magnesium L-Threonate significantly different from conventional magnesium salts such as magnesium oxide or magnesium sulfate.
