6. Calcium
Ideally, pregnant women should ingest 1,500 milligrams of calcium per day. It is best to take this at night (it helps with sleep) in the liquid, powdered or chewable form. Many calcium tablets are simply chalk and do not dissolve in the stomach, and therefore are not absorbed properly. Each cup of milk or yogurt contains 400 milligrams of calcium.

7. Iron
Approximately 18 to 36 milligrams of iron per day can be helpful. Interestingly, iron deficiency can sometimes cause infertility. Also, pregnant women who don't get enough iron are at risk for anemia, fatigue, poor memory and decreased immune function.

8. Water
Be sure to drink plenty of water. When pregnant, blood volume can increase about 30 percent and it is easy to become dehydrated. If your mouth or lips are dry, drink more! Adequate salt is also helpful in preventing dehydration (less so if you have problems with fluid retention).

9. Check Your Thyroid
Millions of women suffer from an underactive metabolism, also known as hypothyroidism, which often goes undiagnosed. This results in fatigue, weight gain and simply feeling like you've run out of gas. Hypothyroidism accounts for more than 6 percent of miscarriages and can be cause for learning disabilities in the child. Treating a low thyroid is both safe and easy during pregnancy. The earlier it is treated the better. Either once you start trying to get pregnant, or as soon as you know you're pregnant, take a Thyroid Stimulating Hormone (TSH) blood test to check your thyroid. Most doctors do not yet know that the TSH has to be less than three — anything above and you need treatment — so look at the test result yourself (many doctors still use the dangerous and outdated criteria of a TSH over five being abnormal). If you like, you can get a lab requisition for a TSH to take to your lab by visiting www.Vitality101.com (click on "online program" then on "Laboratory Requisition Form"). If you were on thyroid medication before getting pregnant, it is normal to increase the dose during pregnancy (the TSH should be kept between .5 and 2.0). If your doctor is not familiar with the new guidelines, he or she can send an email to the Web site above and a copy of the guidelines will be sent to them.

10. Things for Pregnant Women to Avoid
A few cautions for pregnant women: avoid taking more than 8,000 units of vitamin A per day. And don't partake in anything that can raise your body temperature too high (hot tubs, saunas or steam rooms). These have been implicated as possibly increasing the risk for birth defects. Most pregnant women are also, of course, aware that smoking, drugs and alcohol should all be avoided during pregnancy. Exercise, on the other hand, has been shown to be very beneficial and results in babies and moms that are quite healthy.
