Confused about Pregnancy Supplements/morning sickness,etc.

I am a bit confused about what is best to use. I have been taking SuperFood Plus for along time now and recently read that a lot of morning sickness is caused by lack of minerals. If I've been eating a mostly vegan diet with a lot of raw fruits & vegies and taking SuperFood Plus in hopes of preventing morning sickness, then why do I still now have the horrible stuff? Would it be better to take something like MH's Mrs Barefoot that also has the calcium formula in it? Or just keep taking SuperFood and add a liquid calcium formula like Uny makes? Plus right now getting down anything is extremely difficult, but I have to do something or like in the past, the morning sickness turns severe and then I have no other options but medications. I'm also taking milk thistle like I said in another post. I think that is helping some, but I'm having to take a lot to get any relief. Please if someone has experience with this or any ideas let me know. If you've used Mrs. Barefoot or Uny's calcium formula I'd like to know also. Thanks! Tweet
