Although only a very small amount of calcium is needed in the early stages, it is important to add calcium to the pregnant woman in the first 3 months. Therefore, women should take calcium supplements during pregnancy as advised by their doctor.

1. Why do you need calcium supplements for pregnant women in the first 3 months?

Calcium plays the most important role in the formation of bones and teeth and ensures the development of the fetus throughout the entire pregnancy. Usually, in the first 3 months, the mother's body needs to be given about 800mg of calcium per day to ensure the development of the fetus.

Although during pregnancy, the mother's body has resolved the calcium compounds contained in the bones and released into the bloodstream to meet the increased demand for calcium, however in most cases this response is not enough, the mother's body needs more than that. In particular, if the necessary amount of calcium is not provided, the fetus will be negatively affected to development such as: congenital rickets, delayed fetal development, bone malformations,…

In addition, the proper addition of calcium to pregnant women also has a great effect on the health of the mother. If calcium deficiency occurs for a long time, it not only causes fatigue for the pregnant mother, but also causes some phenomena such as numbness of the legs, insomnia, back pain,

2. Some foods rich in calcium are good for pregnant women

The most reasonable time to add iron and calcium to pregnant women is the entire pregnancy, in which the first 3 months play a very important role. Accordingly, pregnant mothers can provide calcium to the body by using the following foods in their daily diet such as:

Milk and dairy foods

This is the most abundant source of calcium for pregnant women. Start the day with a glass of milk that not only meets the amount of calcium needed for the body, but also helps the spirit to be more refreshed, helping the fetus to develop comprehensively.

Dried fruits

Dried plums, dried peaches, dried grapes,… are fruits that contain a lot of energy and nutrients necessary for the body. Moreover, in dried fruits also contain a large amount of calcium, which is very good for the bones and teeth of the fetus during the period of development. However, pregnant mothers should choose dried fruits to ensure food safety so as not to affect the health of themselves and the fetus.


Bananas not only help boost brain concentration, but also contain electrolyses that help prevent bone degeneration and increase calcium intake in the body. If you feel tired, pregnant mothers can eat bananas to provide quick energy to the body.

Also known as spinach, it is a dark green vegetable and contains large amounts of calcium and iron that are good for the health of the mother and the fetus. On the other hand, they also contain a lot of other nutrients such as potassium, phosphorus, zinc, selenium and help protect the liver, helping to strengthen the immune system for pregnant mothers.


Almonds are a very healthy nut, especially pregnant mothers, according to the study of 23 almonds, which provide pregnant mothers with about 75mg of calcium, along with many important proteins and vitamin E.

In addition, to ensure a sufficient amount of calcium loaded into the body every day, pregnant mothers can use calcium supplements for pregnant women as directed by their doctor. This is also the best solution for pregnant mothers who are severely deficient in calcium.

3. Notes when taking calcium supplements for pregnant women

During the first 3 months of pregnancy, the female's immune system declines, so it is necessary to pay attention to the following when using drugs that provide calcium:

  • Good pregnant woman's health condition, no medical biography, can use calcium pills according to the dosage recommended by the doctor
  • For pregnant women with symptoms of gestational diabetes, it is not recommended to use calcium drugs containing sugar or sodium salts, since they can cause hypertension or pre-production conditions that are very dangerous.
  • Calcium pills are usually recommended in the morning or after breakfast 1 hour to bring the best effect. It is not recommended to drink in the evening, which can cause kidney stones or kidney residues.
  • For cases where both iron and calcium are added to the body, pregnant women need to take 2 drugs for a long time apart to avoid conflicts, causing undesirable side effects.
  • In the first 3 months of pregnancy, the amount of calcium to be given to the body 1 day is 800mg, however our body can only absorb a maximum of 500g for one use. Therefore, the pregnant mother should divide into the most reasonable meals to promote the effects of the drug.
