Folic acid, also known as Vitamin B9, is an essential vitamin for the development of the fetus. Taking folic acid in appropriate doses from 3 months before pregnancy to the end of 3 months of pregnancy significantly reduces the rate of fetuses having neural tube defects. This is a fairly common malformation in the fetus such as spina bifida causing paralysis of the lower extremities, urinary incontinence, loss of sensation in the lower extremities .. or more severe such as craniocervical malformations ...
Because Therefore, in addition to folic acid supplements from food, right before planning a pregnancy, women should use folic acid tablets to supplement vitamins and prevent this serious malformation. Doctors will recommend a specific daily dose, the current common dose (recommended by the US Department of Health) is 0.8mg (800 mcg)/day.
In foods, folic acid is abundant in bean sprouts, dark green vegetables such as broccoli, spinach, nuts, milk, bananas...

Iron participates in the formation of red blood cells and has an important role in oxygen transport, so it is essential for pregnant mothers. During pregnancy, the World Health Organization (WHO) recommends mothers Pregnant women should supplement about 30mg of elemental iron per day to prevent anemia. Excess iron taken into the body will not be eliminated but will be stored, so regular iron intake and specific dosage need to be considered.
In fact, taking iron is only really needed if you have iron deficiency anemia, if your iron levels are in the normal range, iron supplements will not bring any benefit. In particular, in cases of people carrying the gene for hemolytic anemia (thalassemia), although the body is anemic, the serum iron level is still very high, then taking iron is contraindicated. The doctor will base on your blood count, serum iron level to make appropriate indications.
In food, iron will be abundant in spinach, lean meat, sea fish, water spinach...

Everyone needs essential minerals to maintain nutrition for the body. Accordingly, calcium is an extremely important mineral component, in addition to building bones and teeth, calcium also participates in the process of movement, circulation, and nerve transmission. During pregnancy, the fetus cannot synthesize calcium on its own, so the mother is the only source of calcium for the baby, this calcium source will be obtained mainly from the mother's bones and teeth. From the 29th week of pregnancy onwards, the fetus will take from the mother an average of 250 mg of calcium / day to serve for bone formation.
Therefore, calcium supplementation is indispensable in the diet for pregnant women both before and during pregnancy. In addition to a calcium-rich diet, it is necessary to supplement calcium through oral tablets. On average, pre-pregnancy women need about 800mg of elemental calcium per day to ensure enough calcium for the body, while pregnant women need to supplement about 1000-2000mg and should not exceed 2500mg of elemental calcium per day. day.
However, like iron tablets, mothers need to pay attention to the amount of elemental calcium and compound calcium, for example, in 1000 mg of calcium carbonate (common calcium pills on the market in this form) there is only 400 mg of pure calcium. and should add organic calcium for better absorption.
To absorb calcium best, pregnant women need to take with appropriate dosage and time, avoid taking with some drugs such as iron, which will reduce calcium absorption.

DHA has a great significance for fetal development. The DHA component in Omega 3 helps develop the baby's central nervous system from the first weeks of pregnancy. In addition, DHA also helps develop the retina of the face, reducing the risk of premature birth, low birth weight. Women should not only drink when they are pregnant, but supplementing with DHA from before pregnancy also provides an extremely important reserve of DHA for the development of the fetus, especially in the first weeks - development of the central nervous system.
DHA is found in foods such as: fish, egg yolks, milk, red meat, nuts... However, providing DHA through Omega 3 pills is the most convenient. The minimum dose of DHA for adults is about 220 mg/day, for pregnant women and breastfeeding about 300 mg/day.

Vitamin D helps absorb and metabolize essential minerals such as calcium and phosphorus into the body. During pregnancy, if the body lacks vitamin D, it will increase the risk such as rickets in the womb, the baby will be born for a long time.
To absorb vitamin D from nature, pregnant women can spend time sunbathing about 20-30 minutes/day or supplement with vitamin D 15mcg/day. The use of foods rich in vitamin D such as cheese, fish, eggs, milk, or foods fortified with vitamin D is also highly effective for pregnant women.

Iodine is an important micronutrient for the development of the fetus, especially the child's nervous system. The need for iodine during pregnancy will also increase. This is a necessary material for the synthesis of thyroid hormone, because pregnant women need one-third more than usual and iodine supplementation is very important for the fetus.
When a pregnant mother has a severe iodine deficiency, it can increase the risk of miscarriage or birth defects. Therefore, iodine supplementation is also very important for pregnant mothers.

Vitamin A helps increase the survival rate of the fetus, necessary for the child's visual development.
Accordingly, the recommended vitamin A requirement during pregnancy is 800 mcg RE/day (RE: retinol equivalent). The main sources of vitamin A are in vegetables such as carrots, papaya, pumpkin), liver, fish oil and dairy products such as yogurt, cheese.
