Health Canada is reminding Canadians about the importance of managing the consumption of caffeine, especially by children, pregnant and breastfeeding women and women who are planning to become pregnant. 

While small amounts of caffeine are not a concern for most Canadians, excessive consumption of caffeine can cause insomnia, headaches, irritability and nervousness. For some groups, like pregnant women, health effects can be even more severe and can include lower birth weights.
