Take Your Bs
You may be accustomed to minding your Ps and Qs, but your Bs are more important during pregnancy. Especially the first trimester when vitamins B6 and B12 can help ease morning sickness. Several studies have linked a 30 mg daily dose of B6 to a reduction in nausea. Others recommend dosages ranging from 10 to 25 mg three times a day. The jury's still out on exactly how much and why B6 works, but as long as you don't ingest more than 100 mg a day (which could cause nerve damage) it can't hurt to give it a try.
Vitamin B12 won't harm you, either, but it could help you keep food down. You'll need anywhere from 4 to 25 micrograms twice a day if you want the vitamin to curb vomiting. If you can't swallow a pill, look for supplements in liquid form. Most compounding pharmacies can whip some up for you.
Of course, you could try to get more B vitamins in your diet by eating red meat, eggs, clams, liver and octopus. For now, though, we think we'll stick to the Bs in pill form.
