You’ve probably heard you need more calcium to have strong bones and a healthy body. However, are you aware of the risks of taking too much calcium? You can overdose on this mineral, and there are side effects.


Your body needs calcium, but it’s important to take the right amount of this important mineral:


  1. Daily calcium requirements. To understand why too much calcium is dangerous, be aware of how much calcium you need to take every day. The recommendations vary based on your age, gender, and health history.


  • In general, children need 1,000 to 1,300 mg a day. Adults need 1,000 mg a day. However, women over the age of 70 need 1,200 mg a day.


  1. One of the most common side effects of taking too much calcium is constipation.


  • This usually occurs if you take too many supplements that have high levels of calcium. It’s rare for you to get constipation from calcium in foods, but it can happen if you overeat.


  1. Kidney stones. You can have a higher risk of kidney stones from taking too much calcium.
