Vitamins and supplements in pregnancy

Certain nutrients play particularly important roles in your baby’s development during pregnancy.

Vitamins and nutrients you need during pregnancy:
 

• Folic acid
• Vitamin D
• Iron and Vitamin C 
• Vitamin B12  
• Omega fats 

Supplements to avoid during pregnancy:
 

• Vitamin A

Folic acid helps reduce the risk of birth defects such as spina bifida. So it’s recommended that you take it for 4 weeks before you conceive, up until the end of your first trimester (12 weeks). As well as taking a 400ug folic acid supplement, it’s important that you eat a healthy, balanced diet. Foods like broccoli, cabbage, beans, brown rice, peas and oranges are rich in folates. So try adding them to your diet.

Iron is one of the key nutrients you need throughout pregnancy. It’s important for carrying extra oxygen around in your red blood cells, and your baby needs it for their developing brain. If you don’t have enough iron, you’ll run the risk of becoming anaemic, which will leave you feeling tired, washed out and generally unwell. So make sure you eat plenty of iron-rich foods such as red meat, fish, eggs, dried fruit, wholegrain breakfast cereals and bread, and green leafy vegetables. Your healthcare professional may also suggest taking an iron supplement. It’s best if you eat iron-rich foods or take your iron supplement with vitamin C. So have a glass of fruit juice with your cereal or some fresh fruit as a starter to your main course. Other foods that contain vitamin C are tomatoes, broccoli, peppers and potatoes.

Getting enough omega 3 fatty acids during pregnancy is important, as they help your baby’s nervous system to develop healthily – and help to keep your own heart healthy too! Omega 3 fats are also important for the development of your baby’s brain and nervous system. Oily fish like sardines, mackerel and salmon are all rich sources of omega 3 fatty acids. But you shouldn’t have more than two portions a week, as the fish can also contain mercury, which can be harmful to your baby in high levels. Seeds such as pumpkin and flax are another source of omega 3 – aim for about two tablespoons a day.

Prenatal vitamin supplements are designed to help you get the right balance of nutrients recommended for a healthy pregnancy, including folic acid and iron. If you choose to take a supplement, make sure it’s one tailored to conception and pregnancy, as regular multivitamins may contain potentially high levels of the vitamins you should be avoiding. And remember, they’re not a replacement for eating a healthy, balanced diet, which will give your baby the best start in life.

Vitamin B12 helps to keep the nervous system healthy and is mainly found in meat, eggs and dairy products. Vegetarians may need to take a vitamin B12 supplement. If you’re unsure, ask your healthcare professional who should be able to help you.

Very high amounts of Vitamin A are not recommended in pregnancy as this could harm your baby.  Some foods such as liver and liver products (e.g. pate) contain very high amounts of vitamin A, so you will need to avoid these.  If you are taking a multivitamin, choose one that is designed for pregnancy as certain “standard” supplements or cod liver oil are high in vitamin A and not suitable for pregnancy.

The good news is that eating a varied diet will ensure you get all the vitamin A you need.
