At London Doctors Clinic, our doctors will sometimes recommend patients take supplements to treat certain medical conditions, which can be bought over-the-counter from any pharmacy. So, we asked our Superintendent Pharmacist, Dipali Khurana, which are the most important supplements that pregnant women should be aware of.


Supplements in Pregnancy

During pregnancy, there are two supplements which you should take on top of eating healthy and balanced diet; Folic Acid and Vitamin D. Multivitamin supplements are not considered to be needed during every pregnancy and are more likely to be an unnecessary expense rather than a health benefit.


1) Folic Acid

Folic Acid is a form of Vitamin B and is particularly important if you are trying to get pregnant. 400mcg of Folic Acid should be taken daily until you are 12 weeks into your pregnancy, as this is when the baby’s spine is developing.

This will lower the risk of the baby suffering from any neural tube defects, which can affect the brain and spine.

You can get folic acid from vitamins and fortified foods, such as breads, pastas and cereals. Folate is found naturally in foods such as leafy green vegetables, oranges, and beans.

Liver is also very rich in folic acid, although it is not safe to eat while you are pregnant or trying to become pregnant. This is because liver is also very rich in Vitamin A, too much of which can cause birth defects in your baby.


Risk of Neural Tube Defects in Pregnancy

Some women have an increased risk of having a pregnancy affected by a neural tube defect and are advised to take a higher dose of 5 milligrams (5mg) of folic acid each day until they are 12 weeks pregnant.

You have an increased risk if:

  • You or your partner have a neural tube defect 
  • You previously had a pregnancy affected by a neural tube defect
  • You or your partner have a family history of neural tube defects
  • You have diabetes


2) Vitamin D

Pregnant and breastfeeding women, need 10 micrograms of Vitamin D daily, and should consider taking a Vitamin D supplement containing this amount.

Vitamin D regulates the amount of calcium and phosphate in the body, which are needed to keep bones, teeth and muscles healthy. Our bodies make vitamin D when our skin is exposed to summer sunlight, however if you are in the sun, take care to protect your skin with sunscreen. Vitamin D is also in some foods, including oily fish, eggs and red meat.

Vitamin D is added to all infant formula milk, as well as some breakfast cereals, fat spreads and non-dairy milk alternatives. The amounts added to these products can vary and might only be small.


3) Iron in Pregnancy

Iron deficiency anaemia is a condition where a lack of iron in the body leads to a reduction in the number of red blood cells.

The most common symptoms include:

Pregnancy is one of the most common causes of iron deficiency anaemia as your body needs extra iron for your baby during pregnancy. Unless you're pregnant, it's rare for iron deficiency anaemia to be caused just by a lack of iron in your diet.


Treating Iron Deficiency Anaemia

Treatment involves taking iron supplements. As well as supplements, good sources of iron include:

  • Dark-green leafy vegetables, such as watercress and curly kale
  • Iron-fortified cereals or bread (wholegrain or wholemeal bread)
  • Brown rice 
  • Pulses and beans (peas and lentils for example)
  • Nuts and seeds
  • Red meat, oily fish and tofu
  • Eggs
  • Dried fruit, such as dried apricots, prunes and raisins


4) Vitamin C in Pregnancy

Vitamin C protects cells and helps to keep them healthy, as well as helping with tissue repair, wound healing, bone growth and repair, and healthy skin. Vitamin C supplements should not be taken during pregnancy however, but instead Vitamin C should be obtained through diet. It is found in a wide variety of fruit and vegetables such as;

  • Oranges and orange juice
  • Red and green peppers
  • Strawberries
  • Blackcurrants
  • Broccoli
  • Brussels sprouts
  • Potatoes


5) Calcium in Pregnancy

Calcium is vital for making your baby's bones and teeth. Calcium can only be absorbed at 500mg at a time, so additional supplements can only be taken at small doses at a time. Sources of calcium include:

  • Milk, cheese and yoghurt
  • Green leafy vegetables such as rocket, watercress or curly kale
  • Tofu
  • Soya drinks with added calcium
  • Bread and anything made with fortified flour
  • Fish where you eat the bones – such as sardines and pilchards
