Synthetic pills or familiar mothers are called synthetic vitamins for pregnant women including medicines or functional foods whose ingredients include vitamins, minerals, essential fatty acids for humans. The combination pill for pregnant women is a synthetic pill with the content of essential nutrients supplemented based on recommendations, scientific research on the role, and dosage of each nutrient for each pregnant woman.

Therefore, taking multivitamins for pregnant women in the current way of saying that many pregnant women are not completely accurate because the supplements themselves for pregnant women often contain vitamins, minerals, essential fatty acids. Therefore, to avoid misunderstandings, in this article, we will use the term Synthetic tablets and Synthetic vitamins as moms often call with the same meaning.

Iron is important for the formation of cells, red blood cells, and the construction of enzymes that help maintain a healthy immune system, protect the body from infections.

CANXI is essential for fetal skeletal development

The composition of synthetic vitamins for pregnant women should be noted


Although the combined pill for pregnant women often has many different ingredients, it can be difficult for women to choose the appropriate supplement. However, among many of these components, there are important components that women need to pay special attention to when choosing, these are:

Acid folic

An ingredient involved in the process of hematopoiesis, preventing congenital neural tube defects in the fetus. Studies recommend that a daily dose of folic acid supplements from a synthetic tablet of between 400 mcg – 600mcg per day is sufficient to prevent these defects. More supplements are not needed unless specifically indicated in high-risk pregnant women. Taking a dose lower than 400 mcg of folic acid daily does not reduce the risk of neural tube defects, supplementing the dose from 800 mcg daily should consult a doctor.


These are the two essential long-chain unsaturated fatty acids for the body and also the two active ingredients that are often confusing and difficult to choose the right preparation for pregnant women, nursing mothers and young children. Depending on the purpose of use, users will choose the formula with the most appropriate DHA / EPA (standardized by the manufacturer). For pregnant, lactating and young children, the optimal DHA / EPA formula is a ratio of 4.5 DHA / 1 EPA, pregnant women can check on the label of the product to know this ratio. Supplementing with DHA / EPA according to this standard formula will help pregnant women prevent some common pregnancy conditions such as pre-eclampsia, eclampsia, gestational diabetes, postpartum depression, etc. DHA is a participant The structure of brain cells and young retina helps to develop children’s intelligence and vision. EPA helps optimize DHA transport across the placenta into the fetus and fight inflammation, increase neurotransmitter transmission.

For cardiovascular and arthritis patients, the selected Omega-3 will contain a higher EPA ratio than DHA due to its stronger anti-inflammatory and vasodilatory effects.

Iodine (Iodine)

Iodine is an important micronutrient for fetal development, especially the young nervous system. Research shows that iodine deficiency or excess can have serious consequences for children and pregnant women.

The amount of iodine needed to supplement from the combined oral tablet for pregnant women can be very different, depending on the needs of the pregnant woman. If mild and moderate iodine deficiency, supplementing with about 100 mcg of iodine per day from supplements is sufficient. To know exactly the amount of iodine moms eat, supplement daily, moms can do a urine test, check the amount of iodine in the urine before adding drugs accordingly, and avoid excess or Iodine deficiency during pregnancy.


Supplementing with synthetic tablets and a diet of around 30mg/day is considered sufficient. If the diet is full of meat, fish, and eggs, iron is often in short supply. A blood test will indicate the body’s iron deficiency to supplement accordingly. The combined oral tablet usually has large amounts of iron ranging from 5mg to 80mg each.

Vitamin A

Helps increase the survival rate of the fetus, essential for the visual development of the child. However, excess Vitamin A can cause birth defects, which have been proven. Therefore, supplementing with Vitamin A from synthetic tablets for pregnant women should be very careful, so choose supplements containing Betacaroten Vitamin A as Vitamin A precursor, safer, supplement about 50- 70% of the daily requirement for Vitamin A from synthetic tablets is moderate because Vitamin A can be obtained from many different food sources, vegetables and fruits.


Help the fetus form and develop skeletal musculature of the child, if this substance is lacking, the mother may have damaged tooth enamel, osteoporosis due to the fetus taking Calcium directly from the mother when it is lacking. The amount of calcium supplementation for pregnant women and nursing mothers about 1,200 mg/day is enough. A diet high in milk, dairy products, and seafood can provide significant amounts of calcium. The rest of the pregnancy can be supplemented with specialized supplements.

In addition to the important nutrients, prone to deficiency, excess during pregnancy above, in the pill for pregnant women also have a number of other nutrients such as vitamins B, Vitamin D3, Vitamin E, Vitamin PP, Magnesium, etc. The content of these active ingredients is often low and similar in synthetic pills and easily replenished from daily food sources.
