- Vitamin D is essential for the absorption of calcium and phosphorus from the small intestine. - These minerals are crucial for bone mineralization and overall bone health. - In children, a deficiency in vitamin D leads to inadequate absorption of calcium and phosphorus, resulting in rickets, a condition characterized by soft and weak bones, bone deformities, and impaired growth. - Iron is essential for red blood cell formation, and its absorption is primarily influenced by factors like Vitamin C. - Sodium and Potassium are important electrolytes, and their balance is regulated by the kidneys and other hormones, not directly by Vitamin D absorption. - Zinc is involved in various metabolic processes, and its absorption is not directly dependent on Vitamin D.
