Question: 1 / 400

A person's bones will become brittle if they are deficient in:

Calcium

Calcium is essential for maintaining strong and healthy bones. A deficiency in calcium can lead to a condition called osteoporosis, where bones become weak and brittle. Calcium is a key component of bone tissue, so without an adequate amount of calcium in the diet, the body will not be able to properly maintain the structural integrity of the bones. Therefore, it is crucial to ensure an adequate intake of calcium to support bone health.

Magnesium, potassium, and sodium are important minerals for various functions in the body, but they are not directly responsible for bone health in the same way that calcium is. While these minerals play roles in muscle function, nerve signaling, and fluid balance, they do not have the same impact on bone density as calcium does.
