Vitamins for pregnant women: dosage and side effects. Complete leadership.

Chapter 1: The importance of vitamins and minerals during pregnancy

Pregnancy is a physiological condition that requires increased consumption of nutrients to maintain the health of the mother and the normal development of the fetus. Proper nutrition plays a key role, but often the diet does not cover all the needs, which makes the intake of vitamins and minerals necessary. The deficiency of certain trace elements can lead to serious complications for both the mother and the child.

• Ensuring the optimal development of the fetus: Vitamins and minerals are involved in all stages of the development of the fetus, from the formation of the nervous tube to the growth of bones and organs.
• Maintenance of mother’s health: Pregnancy makes increased requirements for the mother’s body. Sufficient consumption of nutrients helps prevent anemia, osteoporosis and other complications.
• Prevention of congenital defects: Some vitamins, such as folic acid, play a decisive role in preventing congenital defects, especially defects in the nervous tube.
• Reducing the risk of pregnancy complications: Adequate consumption of vitamins and minerals can reduce the risk of premature birth, preeclampsia and other complications of pregnancy.

Chapter 2: The main vitamins and minerals necessary during pregnancy

It is especially important for pregnant women to ensure sufficient intake of the following vitamins and minerals:

• Folic acid (vitamin B9):
  • Role: It is necessary for the formation of the nervous tube of the fetus in the first weeks of pregnancy. Folic acid deficiency can lead to defects in the nervous tube, such as the crevice of the spine (spina bifida) and anencephaly. It is also important for the growth and division of cells, the formation of red blood cells and maintaining healthy DNA.
  • Recommended dosage: 400-800 mcg per day. It is recommended to start taking folic acid 1-3 months before the planned pregnancy and continue during the first trimester. Women with a high risk of defects in the nervous tube (for example, if there have already been cases of history) may require a higher dose (up to 4 mg per day), prescribed by a doctor.
  • Sources: Dark green leafy vegetables (spinach, Romen salad, broccoli), legumes (beans, lentils), orange juice, enriched cereals.
  • Side effects: In rare cases, allergic reactions, gastrointestinal disorders (nausea, bloating) can be observed. High doses can mask vitamin B12 deficiency.
• Iron:
  • Role: It is necessary for the formation of hemoglobin, which transfers oxygen in the blood. During pregnancy, the need for iron increases, since the volume of blood increases and the fruit must be provided with oxygen. Iron deficiency can lead to iron deficiency anemia, which is manifested by fatigue, weakness, dizziness, pallor of the skin and increased susceptibility to infections. In the fetus, iron deficiency can lead to a delay in growth and development.
  • Recommended dosage: 27 mg per day. In some cases, a higher dose may be required, determined by the doctor on the basis of the results of blood tests.
  • Sources: Red meat, poultry, fish, legumes (lentils, beans), dark green leafy vegetables (spinach), enriched cereals. For better assimilation of iron, it is recommended to use foods rich in vitamin C (citrus fruits, pepper).
  • Side effects: Constipation, nausea, abdominal pain, diarrhea, dark chair. To reduce side effects, it is recommended to start with a low dose and gradually increase it, as well as take iron during food or after eating. Iron can interact with some drugs, so you need to consult a doctor.
• Calcium:
  • Role: It is necessary for the formation of the bones and teeth of the fetus, as well as to maintain the health of the mother’s bones. During pregnancy, the fetus “takes” calcium from the mother’s body, so it is important to ensure its sufficient intake. Calcium deficiency can lead to osteoporosis in the mother and problems with the development of bones in the fetus.
  • Recommended dosage: 1000 mg per day.
  • Sources: Dairy products (milk, yogurt, cheese), dark green leafy vegetables (cabbage, broccoli), enriched products (soy milk, tofu).
  • Side effects: Constructure, bloating. High doses of calcium can prevent the absorption of iron and zinc.
• Vitamin D:
  • Role: It is necessary for the absorption of calcium and phosphorus, as well as to maintain the health of bones and the immune system. During pregnancy, vitamin D is important for the normal development of the bones and teeth of the fetus. Vitamin D deficiency can lead to rickets in a child and osteomination in the mother.
  • Recommended dosage: 600 IU (international units) per day. Some experts recommend higher doses (up to 2000 IU per day), especially for women with vitamin D or dark skin deficiency.
  • Sources: Fish (salmon, tuna, sardines), egg yolk, enriched products (milk, yogurt, cereals). Vitamin D is also synthesized in the skin under the influence of sunlight.
  • Side effects: High doses of vitamin D can lead to hypercalcemia (an increased level of calcium in the blood), which can manifest by nausea, vomiting, weakness, constipation and kidney problems.
• Vitamin C:
  • Role: The antioxidant necessary for the formation of collagen, strengthen the immune system and improve iron absorption.
  • Recommended dosage: 85 mg per day.
  • Sources: Citrus fruits (oranges, grapefruits, lemons), pepper, strawberries, kiwi, broccoli.
  • Side effects: In high doses can cause stomach disorder and diarrhea.
• Vitamin A:
  • Role: It is necessary for vision, the growth of cells, the immune system and the development of the embryo.
  • Recommended dosage: 770 mcg per day. It is important not to exceed the recommended dose, since the excess of vitamin A can be teratogenic (cause congenital defects). It is recommended to receive vitamin A in the form of beta-carotene, which is the predecessor of vitamin A and safe in large doses.
  • Sources: Carrots, sweet potatoes, pumpkin, spinach, mango, apricots.
  • Side effects: Toxicity with an overdose. Symptoms of overdose include nausea, vomiting, dizziness, blurry vision and congenital defects in the fetus.
• B vitamins B (B1, B2, B3, B6, B12):
  • Role: Participate in the energy exchange, functioning of the nervous system, the formation of red blood cells and DNA synthesis.
  • Recommended dosage: Varies depending on vitamin. Typically, prenatal vitamins contain a sufficient amount of vitamins of group B.
  • Sources: A variety of foods, including meat, fish, eggs, dairy products, whole grain products, legumes, nuts and seeds.
  • Side effects: In rare cases, gastrointestinal disorders can cause. Vitamin B6 in high doses can cause neurological problems.
• Zinc:
  • Role: It is necessary for the growth and development of cells, immune function and wound healing.
  • Recommended dosage: 11 mg per day.
  • Sources: Red meat, poultry, seafood, nuts, seeds, legumes, whole grain products.
  • Side effects: In high doses, it can cause nausea, vomiting and reduce the assimilation of copper.
• Iodine:
  • Role: It is necessary for the production of thyroid hormones, which are important for the development of the brain and nervous system of the fetus. During pregnancy, iodine deficiency can lead to a delay in mental development in a child.
  • Recommended dosage: 220 mcg per day.
  • Sources: Iodized salt, seafood, dairy products.
  • Side effects: In rare cases, it can cause problems with the thyroid gland.
