If you have a healthy diet you can just take folic acid and iodine as supplements
Elevit is very expensive and has a lot of things in that you don't really need in tablet form, I mean you will get enough just from eating normal food. All you need is folic acid and iodine. But if you can afford to get Elevit then that is fine to take. It is just a multivitamin for pregnant women :) and congratulations on your pregnancy
