1. Zinc - Inadequate zinc is the most common and problematic deficiency during pregnancy. Zinc is critical for two reasons: proper growth and for developing a healthy immune system for the baby. Be sure to get at least 15 milligrams per day of zinc in your diet, which can be found in high protein foods such as meat and beans.
2. Folic Acid - Getting enough folic acid is critical both before and during pregnancy to help assure proper growth and to prevent birth defects. It is present in deep green, leafy vegetables. Women should get at least 400 to 800 micrograms per day.
3. Magnesium - Magnesium deficiency is routine in the diet and can increase the possibility of high blood pressure and seizures during pregnancy, a condition known as eclampsia. To prevent this deficiency, take 200 milligrams of magnesium daily. Whole grains, green leafy and other vegetables and nuts are good sources of magnesium. Taking the proper amount of magnesium a day also helps to decrease the leg cramps and constipation often experienced during pregnancy.
4. B Vitamins - These are critical for energy, mental clarity and to prevent depression. B vitamins have also been found to improve pregnancy-related complications such as gestational diabetes. Taking 200 milligrams a day of vitamin B6 can improve the health of those women suffering from this form of diabetes. But please note that only women who develop gestational diabetes during pregnancy should take this high level of B vitamins, and should drop the level of consumption to 100 milligrams per day during the last month. For all other soon-to-be moms, take approximately 25 to 50 milligrams a day of B vitamins and plenty of vitamin B12 for normal nerve function.
5. Fish Oils - The human brain is made predominantly of DHA, an essential fatty acid found in fish oils. Regardless, DHA deficiency is very common and it is critical that pregnant women get adequate fish oils so that their baby can develop healthy and optimal brain tissue. DHA may also decrease the risk of postpartum depression.
6. Calcium - Ideally, pregnant women should ingest 1,500 milligrams of calcium per day plus 400-600 units of Vitamin D. It is best to take Calcium at night (it helps with sleep).
7. Iron (Chelated Iron) - Approximately 18 to 36 milligrams of iron per day can be helpful. Interestingly, iron deficiency can sometimes cause infertility. And 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 have undiagnosed hypothyroidism, which accounts for over 6% of miscarriages, and is associated with learning disabilities when the child is born. Treating a low thyroid is both safe and easy during pregnancy. The earlier it is treated the better. As soon as you know you're pregnant (or trying to get pregnant), check a TSH blood test to check your thyroid. If you were on thyroid before getting pregnant, it is normal to need to increase the dose during pregnancy (the TSH should be kept between .5 and 2.0).
10. Things 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.
