Vitamin AD Group
The vitamin AD group comprises vitamins A and D, two fat-soluble micronutrients essential for vision, immune regulation, epithelial integrity, calcium metabolism, and skeletal development. Vitamin A supports photoreceptor function, cellular differentiation, and mucosal immunity, while vitamin D promotes calcium and phosphate absorption, bone mineralization, and neuromuscular stability. Combined formulations are widely used in pediatrics to support growth, prevent rickets and xerophthalmia, and strengthen immune defense. Deficiency states may lead to night blindness, impaired immunity, bone deformities, or developmental delays, whereas excessive intake can result in toxicity due to fat-soluble accumulation. The vitamin AD group plays a critical role in maintaining physiological homeostasis across multiple organ systems.
