Folic Acid and Prenatal Vitamins: A Guide for Pregnancy

Reviewed by Dr Asma, Medical Reviewer at Medimart

If you are planning a pregnancy or have just found out you are expecting, you will probably hear the word folic acid from every aunty, neighbour and doctor. There is good reason for the fuss. Prenatal vitamins are one of the simplest steps a woman can take to support her baby’s early development, yet many women in Pakistan start them late or stop them too soon. This guide explains what prenatal supplements do, which nutrients matter, and how to use them sensibly.

Why folic acid matters so much

Folic acid is the synthetic form of folate, a B vitamin the body needs to build new cells. Its most important job in pregnancy is helping the baby’s brain and spinal cord form properly in the first few weeks, often before a woman even knows she is pregnant. Low folate levels raise the risk of neural tube defects. That is why doctors usually advise women to begin folic acid before conception, ideally at least a month or more before trying, and to continue through the early months. Your doctor will tell you the right amount for your situation, as it differs for women with diabetes, epilepsy, obesity or a previous affected pregnancy.

Other nutrients in a prenatal vitamin

A good prenatal formula covers more than folic acid. Iron supports the extra blood your body makes and helps prevent anaemia, which is very common among Pakistani women. If you are tired, pale or breathless, read our guide on iron deficiency anaemia in women. Calcium and vitamin D support the baby’s bones and protect your own, and vitamin D deficiency is widespread here, as explained in our post on vitamin D deficiency. Iodine supports the baby’s brain and thyroid, vitamin B12 supports nerves and blood, and omega 3 (DHA) is linked with brain and eye development. Not every product contains all of these, so check the label.

How to choose a prenatal supplement

First, look at the ingredient list rather than the packaging. Make sure folic acid or folate is included, along with iron, calcium or vitamin D where your doctor recommends them. Second, avoid doubling up. Taking a prenatal multivitamin plus separate iron, calcium and vitamin D tablets can push some nutrients higher than intended. Third, avoid supplements with high levels of vitamin A in the retinol form, since too much can harm a developing baby, and stay away from herbal mixes that are not clearly labelled. Finally, buy from a trusted pharmacy so you know the product is genuine and stored properly. You can browse the pregnancy care range or compare general multivitamins and ask our team if you are unsure.

Tips to make supplements easier

Some women feel nauseous after taking iron or a large tablet. Taking it with food, at night, or switching to a gentler formula after speaking to your doctor can help. If morning sickness is severe, our guide on morning sickness and first trimester care has practical advice. Constipation is another common side effect of iron, so drink plenty of water, eat fibre rich foods such as fruit, salad, daal and whole wheat roti, and stay gently active.

Food still comes first

Supplements fill gaps, they do not replace a balanced diet. Aim for green leafy vegetables, lentils, chickpeas, eggs, milk, yoghurt, fruit and a little lean meat or fish. Wash vegetables and fruit well, cook meat and eggs fully, and drink only boiled or safe water. Limit tea and coffee, since tea can reduce iron absorption when taken with meals.

Common mistakes to avoid

Do not start random vitamins because a relative recommended them. Do not stop taking supplements the moment you feel better. Do not combine them with herbal remedies without asking your doctor. And do not skip antenatal checkups, because blood tests tell your doctor what you actually need.

When to speak to your doctor

See your doctor if you feel very dizzy, have heavy bleeding, severe vomiting, swelling of the face or hands, headaches with blurred vision, or reduced baby movements later in pregnancy. Mention every medicine and supplement you take at each visit.

Frequently asked questions

When should I start folic acid?

Ideally before you conceive and through early pregnancy, as advised by your doctor.

Can I take a normal multivitamin instead of a prenatal one?

Some multivitamins are not designed for pregnancy and may contain too little or too much of certain nutrients. Ask your doctor or pharmacist to confirm.

Is it safe to take iron and calcium together?

Calcium can reduce iron absorption, so they are often taken at different times of day. Follow your doctor’s instructions.

Do I need supplements if I eat well?

Folic acid is still recommended for nearly all women planning pregnancy, because food alone rarely provides enough in the early weeks.
