vitamins during pregnancy

Before week 12, i took only folic acid. Then, my ob started to prescribe me with prenatal multi vitamins which also contains folic acid & omega-3. U need to check your multi vitamins ingredients, if it already contains those necessary ones, there's no need to take folic acid/ omega-3 separately as it is simply redundant. Usually prenatal multi vitamins will contains the necessary. I feel that if you're able to get very well balanced and sufficient diets suits for pregnancy, multi vitamins may not required. But most of the time, we may not be able to get them all through diet, hence the prenatal multi vitamins come in as a supplement.
