Safe level of caffeine consumption in pregnancy:
According to a study by Jarosz M, et al, entitled Maternal caffeine intake and its effect on pregnancy outcomes, caffeine intake of up to 300 mg per day may not affect pregnancy duration and condition of the newborn baby in a study, but intake should be kept at 200 mgs per day or lower in order to be safe. Research included in this publication by the author found that a study conducted on 509 pregnant women found no relationship between maternal caffeine intake during pregnancy and the risk of premature birth, birth weight or the Apgar score (a method of assessing health) of newborns. A majority of women (98.4%) consumed no more than 300 mg of caffeine per day. Most sources estimate that one 8 ounce cup of coffee contains between 60 and 200 mg of caffeine. In conclusion, during pregnancy caffeine consumption of no more than 300 mg per day does not affect pregnancy duration and the condition of the newborn. (21)
