There are hundreds of herbal and botanical supplements on the market today. Many pregnant women who wouldn't consider taking over-the-counter medications feel that herbal and botanical products are “natural” or “organic” and therefore safe. Never assume that just because a supplement is labeled “natural” or “organic” and is sold over the counter that it is safe to take during pregnancy. Little is known about the effects of herbal, botanical, and dietary supplements on a growing fetus and whether they are safe to use during pregnancy.

The dangers of herbal supplements are many. Supplements do not have to undergo the rigorous and extensive testing required by the FDA for prescription and over-the-counter medications. There are no required standards for the amounts of active ingredients contained in herbal supplements — these can vary wildly among different brands. Some supplements can also interact with medications and reduce their effectiveness.

Warnings

Common remedies used for nausea and vomiting such as red raspberry, wild yam, and homeopathic treatments have not been scientifically studied. Some are known to be harmful. These include comfrey, which may cause liver damage; blue cohosh, which may cause heart defects; and pennyroyal, which could cause spontaneous abortions.

Keep in mind that herbal teas may also contain substances that may not be safe. If you do use herbal teas, don't drink more than a few cups per day, and be sure your doctor knows you are drinking the tea. Teas considered safe include blackberry, citrus peel, ginger, lemon balm, orange peel, and rose hip if they have been processed according to government safety standards. Don't assume these teas are caffeine-free, and always check the label to be sure they include no added substances.

While some herbal ingredients have undergone extensive testing, the safety and effectiveness of many herbal supplements have not been demonstrated at all. To ensure safety, it is best to stay away from any herbal product during pregnancy unless you have permission from your doctor. Don't let herbs become a substitute for medical attention, especially during pregnancy when specific symptoms can be signs of other problems.

If you have bothersome symptoms and do not want to risk taking overthe-counter medications, do not take matters into your own hands by taking what you think is “natural.” Instead, speak to your doctor. Also, be careful of taking the advice of others or the advice of people selling these supplements. These people don't always have your best interest at heart and don't always have all the facts.

Always check with your doctor before beginning to take an herbal supplement or continuing an herbal supplement that you were taking before becoming pregnant. To ensure the best outcome for you and your baby, always discuss any over-the-counter medication, prescription medication, dietary supplement, and/or herbal supplement with your doctor.

Meal Replacement Supplements

You can find all kinds of meal-replacement bars, drinks, and powders on the market today. Are they safe to use? This can be a tricky question. These products are probably safe unless they contain herbal products or other substances deemed unsafe during pregnancy. It is also possible for these products to contain high amounts of vitamins that could be toxic for pregnant women, such as vitamin A. Some may also be high in protein. Even though your protein needs are slightly increased, too much protein can put undue stress on your body. These products are not formulated for pregnant women, and you are best sticking with wholesome foods. If there is a product that you like and want to continue eating, consult with your doctor or a dietitian before making it part of your regular diet.
