Can I get too much calcium from food?
It would be quite difficult to get too much calcium from food. When people consume more than the UL, it's generally from supplements. For example, an adult would have to consume approximately 10 cups of milk every day to go above the UL intake! Don't automatically assume you need a calcium supplement. Check how much calcium you are getting from food first. Experts agree it's best to aim to meet your calcium needs from food if possible. If you can't get enough from food, you may need a supplement.
What happens if I consume too much calcium?
If it happens for a short time, nothing would happen. However, consuming more than the UL of calcium for an extended period of time would put you at increased risk for adverse health effects, such as kidney stones.
