Yes, there can be downsides to taking calcium supplements. Some common side effects include constipation, severe diarrhea, and abdominal pain. Calcium carbonate, in particular, is associated with gastrointestinal side effects like constipation, flatulence, and bloating. It's essential to be aware of these potential side effects and consult with a healthcare professional before starting any calcium supplement regimen.

3. Why shouldn't you take calcium and vitamin D together?
