You'll get most of the vitamins and minerals you need by eating a healthy, varied diet. But when you're pregnant (and while you are trying to get pregnant) you also need to take a folic acid supplement. It's also recommended you take a daily vitamin D supplement – especially in the winter months (October to March) when you don't get enough from the sunlight.
Along with the vitamins you should take, there are also some to watch out for and avoid. You should avoid supplements and multivitamins containing vitamin A (retinol) – as too much of it can harm your baby's development. You should also avoid liver and liver products (including fish liver oil), as they are high in vitamin A.
