How Much Caffeine Is Safe During Pregnancy?

As a coffee lover, I say enjoy your java during pregnancy–in moderation of course.

You’ll hear contradicting advice on this subject from various health experts and even non-health experts. Health Canada and Dietitians of Canada suggest that up to 300 mg of caffeine is safe during pregnancy, and then others like the American Pregnancy Association recommend to avoid it all together if possible. I recommend that pregnant women limit their caffeine intake to about 200 mg per day, which is the equivalent of about one and a half 8 oz cups of coffee/day. Keep in mind though that certain teas, soft drinks and foods also contain caffeine.

Here is a list that you can refer to if you’re wondering about caffeine levels in foods and beverages that you consume:

While enjoying your coffee and chocolate, keep in mind that caffeine  is a stimulant and does cross the placenta/uterine barrier. Over-consumption can cause early miscarriage and can also cause your baby to have a low-birth weight. Side effects of over-consumption include irritability, headaches, dehydration and nervousness.  If you are a coffee lover like me, but plan to cut back during pregnancy, don’t quit cold turkey— you may experience withdrawal symptoms such as headaches. Instead, gently and slowly decrease your caffeine consumption over several days or weeks. Remember, including one, to one and a half cups of coffee a day is likely completely safe for you and your baby if you are already a coffee drinker. Obviously, I would not recommend starting to drink coffee during pregnancy if you did not previously.
