When you're pregnant, you need more of some nutrients, including protein, folate , iodine and iron. Vitamin B12 and vitamin D are also particularly important since they support the development of the baby's nervous system B12 and skeleton D.
Adequate vitamin C intake also helps improve the adsorption of iron from your diet. However, it's better to get the other nutrients you need from a healthy diet rather than from supplements. In most cases, eating a variety of nutritious foods should meet both your needs and those of your baby. Check the Australian Dietary Guidelines for more advice. A multivitamin is a combination of different vitamins and minerals, usually taken as a tablet.
Some multivitamins are designed especially for pregnant women. But they are not a substitute for a nutritious diet. It's important to eat healthily even if you're taking a multivitamin. Your body only needs a small amount of each nutrient, and higher amounts are not necessarily better. In fact, consuming more than you need can sometimes cause harm. For example, high doses of vitamin A , vitamin B6, vitamin C , vitamin D or vitamin E can be dangerous.
It's best not to take these vitamins as supplements in pregnancy. Just as you need to check with your doctor before you take any medicines while pregnant, it's best to talk to your doctor before taking any supplements. Other than folic acid, iodine and any supplement prescribed for you by your doctor, there is limited evidence to support the use of supplements during pregnancy. Emerging research has shown that omega-3 supplements during pregnancy might help reduce the risk of premature birth , and that probiotics might help control blood glucose levels in pregnancy.
But it's not clear whether the benefits of taking these supplements outweigh any possible harms. Until there is better evidence available, it's best to avoid them — particularly in the first trimester of pregnancy. Because nutritional supplements are classed as 'complementary medicines', they are not scrutinised or regulated as much as other medicines.

Here is what you need to know about the benefits for fertility and pregnancy health of folic acid, iodine, vitamin D, zinc, and selenium supplements. Read more on Your Fertility website. There are hundreds of vitamin and mineral supplements on the market.
Should you be taking them? Read more on Queensland Health website. Other supplements, such as fish liver oil, are also high in vitamin A. If you take supplements containing vitamin A, make sure your daily intake from food and supplements does not exceed 1.
Having large amounts of vitamin A can harm your unborn baby. Also avoid taking supplements that contain vitamin A. Speak to your GP or midwife if you would like more information. If you take a supplement that contains vitamin A, do not take too much because this could be harmful.
Liver is a very rich source of vitamin A. Women who have been through the menopause and older men, who are more at risk of osteoporosis, should avoid having more than 1.
