Folic Acid

Whatsapp Order

Folic Acid, also known as Vitamin B9 or pteroylmonoglutamic acid, is a water-soluble vitamin essential for numerous physiological processes including DNA synthesis, repair, and methylation, as well as amino acid metabolism. It appears as a yellow to orange-yellow crystalline powder, odorless or with a faint characteristic odor. Folic Acid is vital for cell division and growth, making it critical during pregnancy and periods of rapid growth. It is widely used in the pharmaceutical, nutraceutical, food fortification, and cosmetic industries due to its role in preventing folate deficiency anemia, neural tube defects in newborns, and supporting overall cellular health.

Folic Acid

Primary Uses

Pharmaceutical and Nutraceutical Industry

Used as a key ingredient in vitamin supplements and multivitamin formulations to prevent and treat folate deficiency anemia.
Essential in prenatal vitamins to reduce the risk of neural tube defects (spina bifida, anencephaly) in developing fetuses.
Employed in formulations for cardiovascular health support due to its role in homocysteine metabolism, lowering cardiovascular disease risk.
Incorporated in supplements targeting cognitive function and neuroprotection.
Used in therapeutic regimens for patients with malabsorption syndromes, certain anemias, and during chemotherapy to mitigate side effects.

Food Industry

Widely used as a fortifying agent in staple foods such as cereals, bread, flour, rice, and pasta to combat folate deficiency in populations.
Added to infant formulas and medical nutrition products to ensure adequate vitamin intake.
Employed in beverage fortification and functional foods designed to enhance nutrient intake.

Cosmetics and Personal Care

Incorporated into skincare formulations for its antioxidant properties and role in DNA repair, promoting skin regeneration and anti-aging effects.
Used in hair care products to support hair growth and reduce hair loss linked to nutrient deficiencies.

Agriculture and Animal Feed

Added to animal feed supplements to promote growth, reproductive health, and prevent deficiencies in livestock and poultry.

Secondary Uses

Biomedical Research

Used as a biochemical tool in studying methylation processes and genetic expression.
Investigated for its potential role in cancer prevention and as an adjunct in chemotherapy protocols.

Environmental Applications

Occasionally utilized in microbial growth media to promote folate-dependent metabolic pathways in fermentation and biotechnology.
