What happens if you take too much folic acid?

Today's women are under increasing pressure in life, and many people get pregnant without any preparation, so they need to supplement a lot of nutrients during pregnancy. Many people take a large amount of folic acid supplements during pregnancy. Some people even take too much folic acid supplementation, so what are the dangers of taking too much folic acid? What is the best way to take folic acid? Let me tell you below.

Folic acid promotes the maturation of young cells in the bone marrow. If humans lack folic acid, it may cause megaloblastic anemia and leukopenia, which is especially important for pregnant women. Folic acid has a great effect, but the more you eat, the better it is. Let's take a look at the symptoms of excessive folic acid.

Folic acid is a water-soluble vitamin and generally will not cause poisoning even if it exceeds the minimum requirement for adults by 20 times. Any amount that exceeds the amount bound to polypeptides in serum and tissues is excreted in the urine.

Possible toxic effects of taking large doses of folic acid include:

1. Interfere with the effect of anticonvulsant drugs and induce convulsions in patients;

2. Oral folic acid 350 mg may affect zinc absorption, leading to zinc deficiency, fetal growth retardation, and an increase in low birth weight babies;

3. Masking the early symptoms of vitamin B12 deficiency, leading to damage to the nervous system.

From 1991 to 1993, based on extensive and rigorous preliminary experiments in the Sino-US cooperative scientific research project on the prevention of neural tube defects, Peking University Medical University and the US Centers for Disease Control and Prevention jointly developed a new folic acid supplement, named "Silian Tablets". It can not only effectively promote the development of the central nervous system and prevent neural tube defects, but also prevent spontaneous abortion, intrauterine growth retardation of the fetus and anemia in pregnant women. At the same time, through experiments, the standard dosage of folic acid supplements was found: 0.4 mg is the threshold concentration with the lowest risk for preventing neural tube defects.

The above is a brief introduction to folic acid. Everyone should be able to see clearly that, in fact, a moderate supplement of folic acid is very good for both the fetus and the mother, if there is nothing abnormal in the body. There is no need to supplement folic acid. Just pay attention to your diet and eat more nutritious foods. You must be relaxed when you are pregnant. Only with a good rest can the fetus grow up healthily.
