What is the main side effect of calcium supplementation?

Nausea
Headaches
Constipation
Dizziness

The correct answer is: Constipation

Calcium supplementation is known to commonly cause constipation as a side effect. Calcium can bind with unabsorbed dietary fats in the intestines, forming insoluble soaps that can lead to constipation. This side effect is well-documented in patients taking calcium supplements. Nausea, headaches, and dizziness are not typically associated with calcium supplementation as frequently as constipation.
