04Product Process & Advantages

High Activity and High Stability

We adopt an advanced process combining chemical synthesis and biocatalysis to ensure the product's high bioavailability from the molecular source.

Highly Selective BioreductionThrough patented catalytic reduction technology, folic acid is precisely converted into the bioactive L-configuration (levorotatory) structure. This fundamentally eliminates interference from inactive isomers and significantly enhances human absorption efficiency.

Calcium Salt Crystal Stabilization TechnologyBy introducing calcium ions to form a stable calcium salt crystal structure, we effectively overcome the technical challenges of easy oxidation and extreme instability in active folate. This greatly extends the product's shelf life and storage stability.

Purification and Quality Control, Benchmarking Top International Standards

Strict Standards

We employ a dual purification technology of multi-stage recrystallization plus ion exchange to precisely remove the inactive D-isomer. It meets the requirements of high-end formulations in Europe and America, with extremely low impurities.

Full-Process GMP

We implement a full closed-loop control from raw materials to packaging, supporting FSSC22000 / HALAL / KOSHER certifications.

05Product Functions & Mechanisms

As a core cofactor in one-carbon metabolism, L-5-MTHF plays a critical role in the methylation cycle:

Genetic polymorphisms of L-5-methyltetrahydrofolate reductase (MTHFR) and implication in methotrexate depletion of systemic folate.

Efficient Anemia Correction and DNA Synthesis:

As illustrated, 5-MTHF is the active endpoint of folate metabolism. It bypasses complex enzymatic reactions to directly supply one-carbon units, ensuring DNA synthesis at the source and preventing anemia.

Regulation of Homocysteine (Hcy) Levels:

L-5-MTHF acts as a methyl donor, promoting the conversion of Hcy into methionine, thereby lowering the risks of cardiovascular diseases and pregnancy-induced hypertension.

L-5-MTHF bypasses metabolic barriers, supporting DNA synthesis to prevent NTDs while directly lowering Hcy levels.

Preconception and Pregnancy Support:

It prevents fetal neural tube defects (NTDs) and is unaffected by MTHFR gene polymorphisms, offering an absorption rate far superior to that of ordinary folic acid.

Promotion of Neurotransmitter Synthesis:

It facilitates the synthesis of serotonin, dopamine, and norepinephrine, helping to improve mood and cognitive health. (This action supports the research and development of formulations for mood balance and cognitive health.)

Key Features

High Bioavailability: As a "ready-to-use" form of folate, it bypasses liver metabolic conversion and enters the bloodstream directly upon intake.

Gene-Friendly

It effectively addresses the MTHFR enzyme activity deficiency that affects approximately 30%-50% of the global population.

High Safety

It prevents the accumulation of unmetabolized folic acid (UMFA) in the serum, thereby avoiding the risk of masking vitamin B12 deficiency.

Superior Stability

The crystalline form ensures excellent chemical stability at room temperature, making it suitable for processing into tablets, capsules, and solid beverages.
