Folic Acid
Brief Introduction:
Folic acid is a water-soluble vitamin, also known as vitamin B9, and is a B vitamin. Folic acid is a derivative of pteridine, it was originally isolated from the liver, later, it was found that the green leaves of plants (such as spinach leaves) are very rich in folic acid. Human intestinal bacteria can also synthesize folic acid, so it is generally not easy to be deficient.
When the human body has poor absorption and metabolic disorders, or long-term use of intestinal probiotics, folic acid deficiency may occur. Folic acid is widely found in pears, broad beans, beets, spinach, cauliflower, celery, citrus, nuts and soy foods. It is also rich in some animal foods, including offal, eggs, fish, etc.
Pregnant women should take more than 350 micrograms of folic acid per day. When the daily intake of folic acid by the human body is maintained at 3.1 micrograms per kilogram per day, the body can have an appropriate amount of folic acid reserves.

Uses: |
1) Biochemical research; clinical drugs are vitamin B family, used for the treatment of pregnancy and infant giant cell anemia. | ||
| 2) Anti-anemia drugs for symptomatic or nutritional giant cell anemia. | |||
| 3) Used as a biochemical reagent, also used in the pharmaceutical industry, etc. | |||
| 4) Folic acid is an anti-anemia drug. When livestock and poultry lack folic acid, their appetite will decrease, their growth will be hindered, and their feathers will grow poorly. Dosage 0.5-1.0mg/kg. | |||
| 5) As a food fortifier. It can be used in food for infants and young children, and the dosage is 380-700 μg/mg; it can be used in special foods for pregnant women and nursing mothers at 2-4 mg/kg. | |||
| 6) Anti-anemia drug; also prevents most neural tube defects (NTDs). | |||
| 7) Used in the polyamide industry to prepare nylon and also as a raw material for saturated polyurethane | |||
| 8) As a feed additive, folic acid is widely used in livestock and poultry such as pigs, dairy cows and chickens. | |||
