As a company specializing in the research and large-scale production of high-purity, high-bioavailability, and targeted delivery magnesium compounds, we offer L-threonate magnesium monohydrate powder-currently the only clinically proven magnesium supplement ingredient that effectively increases brain magnesium levels. Our clients include high-end cognitive health brands, neuroscience formulation developers, and all end-users concerned with memory, concentration, sleep quality, and long-term brain health.
Addressing the industry challenge of traditional magnesium supplements failing to cross the blood-brain barrier, our product, with its unique molecular structure, can efficiently deliver magnesium ions to the cerebrospinal fluid. Through ≥99% optical purity control, comprehensive heavy metal and microbial testing, and low-temperature crystallization processes, we truly solve the core pain point of "magnesium supplementation failing to act on the brain," making magnesium an effective tool for cognitive support.

FAQ
Q: What is the difference between magnesium L-threonate and other magnesium salts?
A: Magnesium L-threonate is a salt of L-threonic acid, a sugar acid derived from vitamin C. It has a unique molecular structure distinct from citrate, malate, glycinate, oxide, and glycerophosphate forms.
Q: Why is the magnesium content lower than other magnesium salts?
A: The molecular weight of L-threonic acid is relatively high compared to other organic acids, resulting in a lower percentage of magnesium by weight (7.0%–8.5%). This is normal for this specific mineral form.
Q: What does the optical rotation specification indicate?
A: Optical rotation (+8.0° to +12.0°) confirms the L-isomer configuration of the threonate. This is a critical quality attribute distinguishing it from D- or DL-forms.
Q: Does Magnesium L-Threonate monohydrate Powder have a taste?
A: It has a mild, slightly sour taste profile. For flavored products, standard flavor masking systems are effective.
Q: Does this product require special handling during formulation?
A: No special handling is required. Standard powder handling practices are sufficient. Avoid exposure to high humidity during processing.
