Description:
Product Overview

As a professional Folic Acid supplier, manufacturer, and factory, Henan Liyin Biotech supplies high-purity Folic Acid in the form of a yellow to orange crystalline powder,
with a minimum assay of ≥97.0% (on dried basis). Our product is fully compliant with USP standards and is manufactured under strict quality controls, ensuring batch-to-batch consistency and global regulatory acceptance for dietary supplement and food fortification applications.
Folic Acid (Vitamin B9) is an essential water-soluble B-vitamin that serves as the precursor to the coenzyme tetrahydrofolate (THF) . THF is a critical cofactor in the transfer of one-carbon units, which are essential for the synthesis of purines and pyrimidines — the building blocks of nucleic acids (DNA and RNA). Consequently, folic acid plays a fundamental role in cell division, growth, and tissue regeneration, particularly in tissues with rapid cell turnover, such as bone marrow and fetal tissues. It is also vital for amino acid metabolism and the formation of red blood cells.
At Henan Liyin Biotech, we supply high-purity Folic Acid in the form of a yellow to orange crystalline powder, with a minimum assay of ≥97.0% (on dried basis), fully compliant with USP standards. Our product is manufactured under strict quality controls to ensure batch-to-batch consistency and global regulatory acceptance.

Dietary Supplements

Folic Acid is a cornerstone nutrient in human nutrition, with its most critical role being in prenatal health. Adequate folic acid intake before and during early pregnancy is proven to significantly reduce the risk of neural tube defects (NTDs) , such as spina bifida, in developing fetuses. Beyond pregnancy, it is essential for everyone to support DNA synthesis, red blood cell production, and cardiovascular health (by helping to regulate homocysteine levels).
- Key Applications: Widely formulated into multivitamin tablets, B-complex capsules, effervescent tablets, gummies, and fortified functional beverages.
- Typical Dosages: In dietary supplements, common dosages range from 400–800 mcg (0.4–0.8 mg) per serving for general adult health, with higher doses (1–5 mg) used in specific prenatal or therapeutic formulations under medical supervision.
- Formulation Advantage: Our Folic Acid exhibits excellent compatibility with other B-vitamins and minerals, making it a reliable choice for complex multi-nutrient formulations.
Food Fortification

Folic Acid is a mandatory fortificant in many countries, added to staple foods to prevent folate deficiency and reduce the incidence of neural tube defects at the population level. It is one of the most successful public health nutrition interventions globally.
- Key Applications: Widely used to enrich cereals, wheat flour, corn meal, pasta, rice, and infant formula to meet regulatory fortification requirements.
- Typical Fortification Levels: In the United States, enriched flour is fortified at a level of 140 mcg (0.14 mg) per 100 grams of flour. Similar mandatory programs exist in over 80 countries, with levels varying based on national regulations and consumption patterns.
- Formulation Stability: Our Folic Acid demonstrates excellent stability in dry, heat-processed foods and is compatible with other B-vitamins commonly used in fortification blends (e.g., niacin, riboflavin, thiamine).
- Key Applications: Widely formulated into multivitamin tablets, B-complex capsules, effervescent tablets, gummies, and fortified functional beverages.
