Limiting Caffeine and Energy Drinks During Pregnancy

Caffeinated beverages are the most commonly used stimulants in the world, with millions of people drinking coffee, soda, and/or tea every day. For more than two decades, highly caffeinated energy drinks have been an extremely popular pick-me-up, particularly among younger adults and teenagers. However, pregnant women should exercise caution when it comes to energy drinks and their overall caffeine intake, according to a UT Southwestern Medical Center expert.

“Energy drinks contain varying amounts of caffeine, so check nutrition labels to understand how much caffeine and other ingredients they contain,” said David B. Nelson, M.D., Associate Professor of Obstetrics and Gynecology and Division Chief of Maternal-Fetal Medicine.

Caffeine consumption of fewer than 200 mg per day is recommended by national standards for anyone pregnant or trying to become pregnant. According to the American College of Obstetricians and Gynecologists, that amount does not appear to be related with miscarriage or premature birth, although the link between caffeine consumption and fetal-growth restriction is unknown.

Caffeine concentration ranges from 50 mg to 500 mg in cans or bottles ranging in size from 8 ounces to 24 ounces. A full-strength 8-ounce cup of coffee has slightly under 100 mg of caffeine, and the quantity in sodas varies greatly. A 12-ounce Coke, for example, contains approximately 34 mg of caffeine, whereas a Diet Coke contains 46 mg and a standard Mountain Dew contains 54 mg.

Small energy shots, usually marketed in 2 fluid ounces, have a high caffeine content – around 200 mg. Energy drink regulation varies by country, but the United States has some of the laxest rules, including content labeling and health warnings. Energy drinks, which are typically sold as nutritional supplements or traditional beverages, are not regulated by the Food and Drug Administration.

According to the most recent issue of Williams Obstetrics, high intake (approximately 500 mg daily) increases the chance of miscarriage by a small amount. Studies considering moderate intake (less than 200 milligrams per day) found no increased risk. A recent research of patients from ten states discovered that regular consumption of caffeinated beverages prior to pregnancy or during the first trimester was not highly connected to birth abnormalities.

Caffeine withdrawal symptoms include headache, weariness and drowsiness, decreased alertness, depressed mood, irritability, and difficulty concentrating, according to Dr. Nelson.

“Gradual reduction in caffeine intake over several weeks before planning pregnancy, or when you find out you are pregnant, can help prevent caffeine withdrawal,” said Dr. Nelson, a Dedman Family Scholar in Clinical Care.

Dr. Nelson recommends the following methods for boosting energy during pregnancy if you choose to avoid caffeine:
