Top 5 Essential Supplements During Pregnancy for a Healthy Baby (Backed by Science)

Introduction

The period of PREGNANCY remains one of the most thrilling as well as challenging moments in the life of a woman. During your time carrying the baby, your body is working extra hard to maintain your health and also to develop your baby. What it implies is that your requirement for some vitamins and minerals rises, and most of the time, it surpasses what meals can offer in general.

A balanced diet in Pregnancy is usually the key to good health, but many specialists suggest the consumption of supplements during pregnancy as a way of covering the gaps. These supplements during pregnancy will assist in guaranteeing that both you and your baby are receiving all you require especially the nutrients: folic acid, iron, omega-3 fatty acid and vitamin D. They all do different and very important tasks such as developing the brain and bones of your baby and maintaining steady energy levels and immune system(1)(2).

In this article, the research will be reviewed regarding the optimal supplements during pregnancy, and the professional suggestions are going to be discussed. Whether you are just entering parent-hood (just pregnant) and wish to become pregnant or you are in your second or third trimester, as a pregnant woman, this guide can help you make good and safe decisions as far as your growing baby is concerned.

What Is The Need to Take Pregnancy Supplements?

Pregnancy is an event of sudden alteration of the baby in the womb as well as for mother body too. The body must have substantive nutrients to aid this miracle process even when compared to normal life. A healthy eating plan is of course the basis of health but sometimes supplements during pregnancy  are necessary to check what is lacking and help the mother and the baby to obtain a good diet. This is why they are important:

a) More Food is Needed by the Mother and the Baby

During pregnancy, the nutritional needs grow by a huge amount. The nutrients in the milk that your baby consumes are the only ones that can support their brain development, aid in the development of bones, and support the growth of organs. At the same time, your body itself needs more energy to assist you in all the shifts, maintain your immune system, and prevent tiredness. The status of these increased requirements can be supported through supplementation with concentrated supplies of nutrients that would not be provided entirely through the diet. So supplements during pregnancy are very important to fulfill the requirements.

b) Some Nutrients Requirement Difficult to Complete by Using Food Alone

No matter how well you eat, you may not get all the daily levels of some important nutrients through food alone. For example, folic acid is the vitamin that is vital to the prevention of birth defects, but is very difficult to absorb in sufficient quantities without a supplement. The amount of iron required during pregnancy is almost twice the normal amount, and a lot of women are unable to get it through food. So that’s why it is important to take supplements during pregnancy.

DHA is the omega-3 fatty acid that helps to develop the brain and eyes and fatty fish is the prominent source of DHA, which pregnant women are scared of taking because of mercury. When this happens, supplements come in as a fail-proof mechanism to make sure you are not lagging behind(2).

c) Prevention of Pregnancy Complications

It has been scientifically proven that certain supplements during pregnancy are effective in the prevention of common complications of pregnancy(1). By consuming folic acid before and during early pregnancy, the possibility of having the defect can be substantially limited. Anemia can be prevented by taking iron supplements during pregnancy, and this may result in fatigue and premature birth. Vitamin D and calcium aid bone health, which is likely to reduce the risk of pregnancy-related complications such as preeclampsia and low birth weight. With supplements during pregnancy, you minimize risks so that your body can provide you with an easy, healthy pregnancy.

Supplement with a Healthy Diet

Interestingly, it is worth finding out that supplements during pregnancy are not a replacement for the actual food. More of them are, actually, additions to it. Whole foods constitute multi-dimensional nutrients, dietary fiber, and antioxidants that otherwise would be lacking in the supplements themselves. However, during pregnancy, your nutritional needs might be higher than what we may not consume through diet alone, and this is magnified with the nausea, food aversions, or induced appetite. In this case, supplements during pregnancy are only considered a side benefit, and they assist you in supplementing meals and attaining the daily requirements.

1) Folic Acid – The Neural Tube Protective Vitamin(B9)

As a nutrient, folic acid is important to ensure that a pregnant woman has a healthy pregnancy due to the early stage of fetal development. It is a supplement that is good for pregnancy. It is also very essential in the development of the neural tube of the baby, which gives rise to the brain and the spinal cord. Since the neural tube develops so early on, in many cases, even before the woman realizes that she is pregnant, it is essential to have sufficient amounts of folic acid as early as the beginning of the development process.

That is why so many healthcare givers suggest not taking folic acid supplements during pregnancy only, but also in case you are planning on conceiving(1)(2).

First Trimester

The first trimester is a critical stage of pregnancy, particularly regarding the development of the baby in the aspects of its brain and spine. Folic acid helps in sealing of the neural tube that takes place within the initial 28 days of conception. A deficiency in folic acid in a woman at this vulnerable period will result in failure to close the neural tube, leaving severe birth defects, which may be mild to severe. Although folic acid plays a particular role during early pregnancy, throughout the pregnancy, it remains imperative since its intake contributes to healthy cell division and tissue formation.

Birth Defects Prevention

Prevention of the most notable among the effects of folic acid is the prevention of neural tube defects (NTDs), one of the most well-known of which is the occurrence of spina bifida, which is prevented through the consumption of folic acid. These are some of the reasons why prenatal supplements are relevant.  Spina bifida has something to do with the failure of the neural tube to close properly, hence damaging the spinal cord and nerves. It has the potential to cause physical and intellectual difficulties that may result in lifelong difficulties.

Anencephaly is another form of neurological tube defect that has effects on brain development. Research indicates that prior to and during early pregnancy, sufficient folic acid reduces the occurrence of NTDs by 70% or more. So it is important to take supplements during pregnancy to avoid such pregnancy problems and conditions.

Daily Recommended Dosage

World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC), recommend that women of childbearing age should take 400 to 600 micrograms (mcg) of folic acid on a daily basis. Valtrex dose can be administered at 4000 mcg/day, or adults can be monitored in the second gestation in already infected women who wish to have a second child. Some of the pregnancies are unplanned, and it is common to be advised to take some folic acid daily even before conception to make sure your body is supplied with this essential nutrient at any given moment(1).

2) Iron (Fighting Tiredness and Supporting Blood Volume)

Iron is the most essential mineral in pregnancy. It plays a role in the making of hemoglobin, which is a constituent of the red cells in your blood; it carries oxygen. Your blood pump volume increases to 50 percent so that it can support you even when you are pregnant woman. To fulfill the body, it is necessary to have iron supplements when a woman is expecting.

When you are pregnant, your body requires an extraordinarily large amount of iron. Iron deficiency can cause fatigue, faintness, and susceptibility to infections. This is the reason why iron is regarded as one of the most important supplements during pregnancy.

The Reason Why Iron Requirement Rises by Nearly Two Times In Pregnancy

Pregnancy requires nearly three times more iron. Generally, women will need approximately 18mg of iron in a day, but when pregnant, the dose is increased to 27mg daily. This is because your body is striving hard to increase the production of blood to provide oxygen to your baby. Simultaneously, the baby is also in the process of stocking up on iron in the initial months of life, particularly in the third trimester. In case your iron needs are insufficient to cater to this accelerated need, then iron deficiency could result, causing trouble to both the mother and the baby.

Top Most Iron Supplements and their Absorption

Pregnant women most of the time take iron supplements throughout their pregnancy so as to meet their iron requirements. The iron supplements are also available in numerous forms, such as ferrous sulfate, ferrous gluconate, and ferrous fumarate. They can be rather effective; however, they might have a side effect, e.g., constipation or even nausea.

Vitamin C (orange juice, etc, which is generally recommended to accompany iron supplements during pregnancy, can cause stomach upset without taking iron supplements with calcium-rich foods and dairy products, which are well-known to inhibit iron(3).

To achieve optimum results, you need to take your iron supplements (during pregnancy) without food when your stomach is empty. Taking it at between-meal intervals is also acceptable.

3) Omega-3 Fatty Acids

Omega-3 fatty acids, of which DHA (docosahexaenoic acid) is the most important, are vital fats meaning, that without them the pregnancy cannot progress normally. The body cannot make these healthy fats in adequate proportions, and therefore, you have to get them in your diet or through supplements during pregnancy. Pregnant women will also benefit a lot with omega-3s in that they will aid in brain and eye development of the baby thus contributing to the overall healthy pregnancy(1).

Role in Development of Nervous System and Eyes

One of the predominant components of the brain and retina is DHA which is an omega-3 fatty acid. In the third trimester of pregnancy, the brain and eyes of the baby develop rapidly and omega-3 fatty acid is essential in developing them. Sufficient Omega -3 fatty acid has also been associated with enhanced cognitive ability, enhanced sight, and more comfortable development of the nervous system in infants.

The baby gets omega-3 fatty acid through a direct supply made to the mother hence the concern that pregnant women should ensure that they have the best amounts of these nutrients through food supply or even supplements during pregnancy. Shortage of omega-3s at this age can affect the long-term brain and eye health of the baby.

Linked With Right Birth Weight and Reduce Preterm Labor

Studies have also revealed that omega-3 fatty acids have other advantages, other than development of the brain and the eyes. Increased intake of omega-3 supplements during pregnancy are associated in several research findings, such as a decrease in the risks of preterm birth, a key factor of infant health complications.

Omega-3s can also be used to extend gestation because they minimize inflammation and maintain hormonal stability, and both are effective solutions to the early labor problem. Moreover, higher birth weights have also been linked to omega-3 supplementation that is a crucial determinant in alleviating the possible occurrence of complications in babies.

To mothers, omega-3s supplements during pregnancy can also aid to stabilize mood and reduce chances ofdeveloping post partum depression due to its inflammatory reducing factors and the fact that it sustains the health of the brain.

Overall omega-3 fatty acids supplements during pregnancy are essential to the growing brain, eyes, and nervous system of your baby. They are also associated with a safer pregnancy, lower chances of an early birth and a healthy birth weight. Getting plenty of omega-3 fatty acids with salmon, walnuts, and flaxseeds in diet is safe, science-based step and every pregnant woman should consider this(1).

4) Vitamin D

Vitamin D is one of the best supplements during pregnancy, which strengthen bones, boost immune system, and maintain hormonal balance. It is known to be one of the best supplements during pregnancy because it assists the body in the absorptionof calcium and phosphorus which are vital components in the formation of bones and teeth of your baby. The work of Vitamin D is much more than skeletal support.

It regulates immune system and linked with lowering gestational diabetes and risk of preeclampsia. Unluckily, most pregnant women are vitamin D deficient, the women who have limited exposure to the sun or have darker skin color. This is why it is so important to learn about its role and how one can obtain enough of it. It is considered to be one of the most important and top supplements during pregnancy(1).

Relationship Between Low Vitamin D And Gestational Diabetes, Preeclampsia

Vitamin D deficiency has been associated with an increase in the chances of severe complications during pregnancy. Women with a lack of vitamin D are more likely to have gestational diabetes, whereby the amount of blood sugar in the body is too high when a woman is pregnant. The researchers think that vitamin D influences insulin sensitivity and the process of using glucose to maintain a normal level of blood sugar.

Preeclampsia is another low vitamin D related condition and is a potentially fatal pregnancy complication with features of high blood pressure and organ stress. Vitamin D can seriously reduce the inflammation and help in blood vessels functioning, which may help decline the risk of preeclampsia. Such connections cause vitamin D to be not a simple support to bones but a guardian of maternal health in pregnancy(1).

In Pregnency Vitamin D3 vs Vitamin D2

In supplements case, there are only two basic forms of vitamin D: D2 (ergocalciferol) and D3 (cholecalciferol). Although both of them are able to contribute to the rising of vitamin D in the body, studies demonstrate that vitamin D3 is more effective at raising and maintaining blood levels of vitamin D when compared to vitamin D2. D3 is the form your body creates by itself when exposed to sunlight. That is why the majority of professionals and prenatal supplement producers use vitamin D3 to assist pregnant women.

Experts Dosage Recommendations

The dosage may differ slightly according to various Health organizations but most recommend that supplements during pregnancy are very important and pregnant women take around 600 IU (International Units) of vitamin D daily. Nevertheless, other sources claim that doses of up to 2,000 IU or even 4,000 IU per day are more efficient, particularly in case of deficiency in women. The best thing to do is to get tested of vitamin D level when you are pregnant and to consult your healthcare provider according to your own needs(1).

5) Iodine

Iodine is a trace mineral and has a potent impact during pregnancy,. It is known as one of the best supplements during pregnancy. It plays an important role in formation of the thyroid hormones that are crucial in controlling the body temperature, metabolism, and energy(1). The iodine requirements of a woman during pregnancy rise dramatically since the woman needs to supply her thyroid gland with iodine and also sustain that of her growing baby and its brain and nervous system. A lack of iodine may really be harmful to both mother and child. This is the reason why iodine supplementation is frequently prescribed as an element of an overall prenatal diet.

Role In Neurological Development

The most popular property of iodine is healthy thyroid balance. The thyroid gland has the role of using iodine to manufacture hormones, which regulate the metabolism of the body. The hormones also play a key role in the development of fetus especially the brain and the nervous system of the baby during pregnancy.

During the first trimester the fetus relies completely on the mother thyroid hormones and as such sufficient iodine during the early stages is particularly important. It can only be fulfilled if iodine supplements during pregnancy are taken up regularly. Prenatal inadequacy may slow cognitive development, reduce IQ levels in children, and create a potential risk of developmental deficiencies. Having adequate iodine levels assist in inducing normalcy in terms of metabolism as well as neurological development.

Methods of Iodine Supplements

Potassium iodide though more common and preferable is available in most prenatal vitamins. This form is readily absorbed and efficient in sustaining thyroid working. However, not all prenatal vitamins have iodine, so must check the label before consuming them or you should consult your health care provider to make sure that you are getting at least the recommended dosage. Health authorities recommend about 220 micrograms of iodine a day among pregnant women.

Beginning and Leaving Supplements During Pregnancy

It is important to know when to start and when to quit taking supplements during pregnancy just as it is to know what to take. Supplements also offer specific nutrition that is required at various stages of motherhood, whether planning a pregnancy, during pregnancy carrying the baby, and after delivering.

Timetable For Supplementation: Preconception, Pregnancy, and Postpartum

The best time to start supplements during pregnancy is pre-conception, that is, one month before. This is particularly significant to nutrients such folic acid which works best in preventing neural tube defects when consumed prior to and or in early weeks of pregnancy(1).

Nutritional support needs do not stop with the birth. In the postpartum, especially among breastfeeding mothers, certain nutrients such as vitamin D, calcium, DHA, as well as iron, are still very important. The mother can also receive postnatal supplements during pregnancy to increase depletion stores and aid in recovery and milk production.

Partition of Supplements During Pregnancy According to Trimester

Pregnancy is categorized into three trimesters and every pregnancy phase comes with varying food priorities and supplementation.

Folic acid, vitamin B6, and iron are essential during the first trimester and help prevent birth defects as well as assist in reduction of vomiting.

During the second trimester, rapid growth of the baby begins, with some of its bones and organs developing more rapidly than others; therefore, calcium, magnesium, and vitamin D are of utmost importance.

In the third trimester the baby piles weight, and during this period, iron, DHA, and choline further becomes pivotal toward brain growth and avoidance of complications such as low birth weight or preterm birth.

Conclusion
