Eating a wide variety of foods in pregnancy will help you to get the most of the vitamins and minerals you and your babies’ need. But there are some supplements such as folic acid and iodine you should take to give your babies the best chance of being healthy.

Folic Acid

Doctors and midwives recommend that you take folic acid for at least a month before becoming pregnant and until you’re 12 weeks pregnant. This reduces the risk of your babies’ having brain and spinal problems.

If you find out that you’re pregnant and you haven’t been taking folic acid, start taking it as soon as possible. Keep taking it until you’re 12 weeks pregnant.


Doctors and midwives also recommend that you take an iodine supplement containing 150 mcg (micrograms) while you’re pregnant and breastfeeding, as your needs increase during this time. Your babies’ also need iodine to grow and develop normally.

Essential fatty acids

Essential fatty acids help form your babies’ nervous system and other tissues.

To increase your essential fatty acid intake:

  • eat oily fish such as salmon, tuna, sardines, either fresh, canned or frozen, once or twice per week (30 g)
  • eat a small handful of raw nuts and seeds every day, such as walnuts, almonds, peanuts, sunflower seeds
  • use sunflower, canola, or olive oils
  • choose margarine over butter
  • regularly choose eggs as a convenient cheap meal or snack.
  • eat plenty of vegetables every day, particularly dark green types, such as spinach, broccoli, green peas and green beans.


During multiple pregnancy, your iron requirements are almost double. Lack of iron can result in anaemia making you to feel more tired than usual. Red meat such as lean beef and lamb are the best sources of iron. Other good sources include:

  • chicken and fish
  • legumes, such as chickpeas, lentils, kidney beans, baked beans
  • nuts and seeds
  • wholegrain breads
  • iron-enriched breakfast cereals – choose a cereal with at least 3 mg of iron per serving
  • dried fruit, such as apricots, raisins, figs
  • green leafy vegetables such as silverbeet, spinach, watercress
  • tofu and tempeh (fermented soybeans)
  • spreads such as Marmite, Vegemite, peanut butter.

Although liver is a rich source of iron, you should only eat small amounts (no more than 100 grams each week). This is because liver contains very large amounts of vitamin A, which can harm growing babies.

Vitamin C helps us to absorb up to four times as much iron from our food. You can get vitamin C from many fruits (berries, feijoas, kiwifruit, mandarin, orange, rock melon, tamarillo) and vegetables (broccoli, capsicum, cauliflower, tomato). Try to include fruit or vegetables with every meal, especially if you’re vegetarian.

Tea, coffee and milk drinks can decrease iron absorption so only drink these between your main meals.

If you’re not able to get enough iron from your diet you may need to take an iron supplement. Your LMC or doctor will advise what is most appropriate for you.

Some drinks, foods, and medications make it harder for your body to absorb iron. Take iron supplements one hour before or two hours after having:

  • tea or coffee
  • milk, yoghurt or cheese
  • calcium supplements
  • antacids, such as Mylanta and Quick-Ez


Calcium is important for the formation of your babies’ bones, particularly in the last months of pregnancy when babies are growing rapidly. You need 1000 mg of calcium per day. you can get this by eating a varied diet and including at least 3 servings of milk and milk products each day. A serving is 250 ml of milk, 1 pottle of yoghurt (150 g), or 2 slices of cheese (40 g).

Milk and milk products such as cheese, yoghurt and custard are the best sources of calcium. Other good sources of calcium include:

  • calcium-enriched almond, rice or soy milk
  • canned fish with soft edible bones, such as salmon and sardines
  • nuts and seeds
  • dark green leafy vegetables
  • tofu.

If you can’t get enough calcium from your diet, you may need to take a calcium supplement. Talk to your LMC or doctor for advice. The best calcium tablets are those that contain around 600 mg of calcium per tablet, such as Caltrate.

Vitamin D

Vitamin D helps your body to absorb calcium and maintain strong bones. Food sources of vitamin D include eggs, oily fish, and vitamin D enriched foods such as some types of milk, yoghurt, and margarine. It’s very difficult to get enough vitamin D from food alone and the best source of vitamin D is sunshine directly on your skin (not through glass or with sunscreen on). Twenty minutes a day is recommended, but in summer limit this to before 10 am and after 4 pm to avoid sunburn.


Zinc is essential for your babies’ growth. The best sources of zinc are lean red meat, chicken, wholegrain breads and cereals, legumes, nuts, seeds, and dairy products.

Multi-vitamin pregnancy supplement

If you’re eating well and choosing daily from the four food groups you shouldn’t need to take a multi-vitamin supplement. But you may need one if you’ve had severe morning sickness and have been vomiting often.

If you take a multi-vitamin supplement choose one that is designed especially for pregnant women. Regular multi-vitamin supplements may contain too much vitamin A and this can harm your babies.

Thiamine (Vitamin B1)

Thiamine helps your body turn food into energy. Food sources include wholegrains, meat and fish. If you were vomiting a lot in early pregnancy you may have been prescribed thiamine. Continue to take this until you’re eating normally again and the vomiting has stopped.

Vitamin B12

Vitamin B12 helps keep your body’s nerve and blood cells healthy. It helps make DNA, the genetic material in your cells. It also helps prevent a type of anaemia that can make you feel tired and weak.

B12 is found only in animal foods or specially fortified foods, such as Marmite, So Good soy milk, Special K breakfast cereal.

If you eat little or no animal foods, talk to your LMC or doctor as you’ll need to have a blood test to check your B12 levels. If your level is low, you’ll need a vitamin B12 supplement or vitamin B12 injection.
