Description

Magnesium L-Threonate is a highly bioavailable organic magnesium salt complexed with L-Threonic acid. This compound is specifically valued for its superior ability to cross the blood-brain barrier, enhancing magnesium levels in the brain more effectively than other forms. It is primarily sought after by manufacturers in the nutraceutical, dietary supplement, and pharmaceutical industries for formulating cognitive support and neurological health products.

Application

• Dietary Supplements & Nutraceuticals: As a key active ingredient in formulations designed to support memory, learning, and overall cognitive function.
• Pharmaceutical Intermediates: Used in the research and development of prescription and over-the-counter medications targeting neurological conditions.
• Functional Foods & Beverages: Incorporated into health-focused food and drink products to enhance their nutritional profile for brain health.
• Sports Nutrition: Utilized in supplements aimed at supporting cognitive performance, focus, and stress management in athletes.
• Clinical Research: Serves as a critical material in preclinical and clinical studies investigating magnesium's role in neuroprotection and synaptic plasticity.
• Veterinary Supplements: Applied in pet health products aimed at supporting cognitive function and nervous system health in aging animals.

Quality Control

Our Magnesium L-Threonate is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and heavy metal content. A Certificate of Analysis (COA) documenting purity (typically ≥98% by HPLC), residual solvents, and microbiological limits is provided with every shipment to ensure traceability and compliance for your GMP-sensitive applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking and degradation.
