Respuesta :
Weak bones would come from a lack of vitamin D since it aids in calcium absorption.
Bones require enough quantities of calcium in order to function properly; otherwise, bones would become fragile and weak. Calcium is obtained through diet, but vitamin D is needed for the calcium in food to be absorbed in the intestines. Calcitriol is the name given to vitamin D in its active state. Calcitriol affects the active transfer of calcium from the food being digested into the intestinal cells of the intestines. Even someone who consumes sufficient of calcium is at risk for developing calcium deficiency since the absorption of calcium in the intestines is significantly decreased when calcitriol is absent. Since calcium is necessary to maintain strong bones, low vitamin D levels can also have an impact on calcium levels.
