These are the best known benefits and for which the integration of folic acid during pregnancy.
Taking folic acid during pregnancy is essential for the proper development of the fetus, especially for the prevention of certain birth defects of the neural tube – the structure that will create the nervous system and spinal column in the first few weeks of pregnancy – such as spina bifida (the spine develops two endings instead of one), anencephaly (lost or incorrect brain development).
Spina bifida involves problems of various types, some correctable with surgery, while others cannot be solved by surgery, such as paralysis of the lower limbs, difficulty in controlling the bowel and bladder, difficulties in physical and mental development.

What is the dose of folic acid?
This vitamin becomes toxic if taken in large amounts. The administration of folic acid contained in multivitamins or prenatal vitamins limits the risk of toxicity that the substance presents, compared to the case when it is taken through supplements almost exclusively enriched with it. In any case, the doses must be contained within the recommended minimum limits.
The recommended doses for adults correspond to a dose of 800 mcg of folic acid per day. Most of this amount must come from the diet, however special conditions or otherwise in cases where deficiencies of this substance occur, may require the intake of this vitamin through food supplements. These compounds are often used during pregnancy and lactation to achieve recommended minimum daily levels.

For women of childbearing age, a minimum daily intake ranging from 400 to 800 mcg of this vitamin is recommended. In any case, folic acid intake should not exceed 1000 mcg per day. Excess of this vitamin inhibits the absorption of vitamin B12 .
When is folic acid supplementation necessary?
Folic acid supplements are mainly prescribed during pregnancy to prevent fetal malformations, but there may be other cases where supplements are recommended by the doctor, for example, when following a diet low in folate, with few fruits and vegetables, and when blood homocysteine levels are high and can pose risks to circulation.
Recent studies have shown some properties of this vitamin in preventing cancer. Low levels of this vitamin in the blood have been found to increase the risk of some types of cancer.
Cells, on the other hand, require the presence of this substance to create and maintain, over time, cells and DNA in good condition. Because of this link, it is inevitable that an insufficient presence of folate will inhibit the body’s ability to repair damaged cells. Thus, this condition is favorable for the production and development of cells that have abnormalities, that is, they are cancerous.
Signs of folic acid deficiency :
It is no coincidence that folic acid was discovered by studying cases of anemia . Anemia is the greatest pathological risk in case of folic acid deficiency . Vitamin B is essential, among other things, for cell development, especially for red blood cells. Deficiency of this vitamin can occur due to lack or difficulties of absorption.
In the first case, it is due to dietary problems. A diet low in foods that contain folic acid inevitably leads to anemia if not supplemented. In the second case, the lack of absorption may be due to kidney problems, such as in dialysis patients, or in alcoholics. However, some anti-cancer drugs or drugs to fight rheumatoid arthritis can cause difficulties in the absorption of folic acid .
