Vitamin b9 itself does not have vitamin activity – it acquires it after conversion in the body into folic acid (citrovorum factor). Due to the fact that folic acid is involved in the synthesis of metal groups, it reduces the human body's need for choline and methionine. It activates choline esterase, influences the formation of purines, stimulates the exchange of Pantothenic, nicotinic acids, and provokes the synthesis of cyanocobalamin. Vitamin plays a special role in the formation of blood elements (erythrocytes), in the synthesis of pyrimidines and purines, in the question of the effect on the functional state of the liver and bile secretion. B9 is a vitamin that prevents the development of liver obesity and atherosclerosis.
The Human body is saturated with folic acid due to food intake and endogenous synthesis of microbial intestinal flora.
Daily folic acid requirement acid
Due to the vital activity of the beneficial intestinal microflora, a person receives a small amount of vitamin b 9 every day. If consumed food in the body receives an excess of vitamin, it will begin to accumulate in the liver cells. These reserves protect people from hypovitaminosis B9 for a long time – 3-6 months.
It is Important to remember that the intensity of excretion and absorption of folacin in the body depends on a large number of factors, the main of which is the method storage and cooking. With high temperature treatment or improper storage, up to 90% of the folic acid contained in the products is destroyed.
The Need for an adult is 400 µg per day, for pregnant women – 800 µg, for nursing mothers – 500 µg, for children under one year – 50 µg. The maximum can be consumed up to 1000 mcg per day.
Folic acid Functions:
- participates in the synthesis of amino acids;
- provokes the synthesis of leukocytes and erythrocytes;
- supports the state of systems and organs in the body;
- important for normal growth and development of the child.
Vitamin B9 Deficiency in the human body
Hypovitaminosis is associated with inhibition of the microbial flora of the intestine (due to taking antibacterial drugs – sulfanilamides, antibiotics, etc.), insufficient food intake, with poor protein diet, using aminopterine (folic acid antagonist), as well as violations of the absorption functions of the intestine.
Deficiency of vitamin B9 is manifested in the form:
- hemorrhagic renal degeneration;
- fatty infiltration of the liver;
- development macrocytic anemia of pernicious type.
Excess vitamin B9 in the human body
To Achieve excess folic acid derived from food, is almost impossible. If hypervitaminosis was caused by vitamins with folic acid, children have digestive disorders, increased nervous excitability, and adults, in addition to these symptoms, suffer from sleep disorders.
Where is contained?
Intestinal Bacteria are not capable meet the body's needs for folic acid.
It Should be remembered that vegetables and meat lose up to 90% of vitamin B9 when cooking, and when frying – up to 95%.
Natural vitamin B9, which is contained in the products, is absorbed normally by 50%, and if there are violations in the digestive system – only 20%.
Synthetic vitamins containing folic acid are more readily available for absorption.
Maximum amount of substance in vegetable products are noted in: dates, mushrooms, pumpkin, tomatoes, carrots, beets, nuts, oatmeal and buckwheat, legumes, cabbage, parsley, green salad, leek, spinach, sprouted grains of wheat.
For example, in 100 gr. sprouted wheat grains contain 350 µg of folic acid, per 100 g. peanuts or liver – 240 mcg, spinach – 200 mcg.
From animal products are: fish (herring, sardine, flounder, tuna), lamb, pork, beef, egg yolk, chicken, beef and pork liver, dairy products.
