Doctors usually advise pregnant women to reduce their caffeine consumption. Many authorities around the world have looked into the effects of caffeine. Health Canada scientists conducted an extensive review of the scientific literature on caffeine (Nawrot et al., 2003). Based on this review, they concluded that the general population of healthy adults is not at risk for potential adverse effects from caffeine if they limit their consumption to 400 mg per day. Most recently, this has been confirmed by the European Food Safety Authority (EFSA, 2015). However, EFSA recommends that pregnant and breastfeeding women limit their daily caffeine intake to 200 mg per day.
The rules for the labelling of caffeine containing beverages are the same across the EU (Food Information to Consumers Regulation (EU) No 1169/2011) Beverages containing more than 150 mg/l must indicate the caffeine content and carry the advisory statement “High caffeine content. Not recommended for children or pregnant or breast-feeding women” followed by the caffeine content in brackets expressed in mg per 100 ml on the label.
Typically energy drinks have a caffeine content of approx. 32 mg per 100 ml and declare their caffeine content on the label, so consumers across the EU can make informed choices.
