What vitamin supplementation is commonly emphasized in the management of cystic fibrosis?

In the management of cystic fibrosis, supplementation with fat-soluble vitamins A, D, E, and K is commonly emphasized due to the malabsorption issues that arise from the condition. Cystic fibrosis can lead to pancreatic insufficiency, which means the body struggles to digest and absorb dietary fats effectively. Since vitamins A, D, E, and K are fat-soluble, their absorption is significantly impaired in patients with cystic fibrosis.

Vitamin A is essential for vision and immune function, vitamin D for bone health and calcium metabolism, vitamin E serves as an antioxidant, and vitamin K is critical for blood coagulation. Due to these vitamins being crucial for various bodily functions and their poor absorption in cystic fibrosis, ensuring adequate levels through supplementation is paramount.

While other vitamins such as vitamin C and B12 serve important roles in the body, they do not require the same specific management approach in cystic fibrosis treatment as the fat-soluble vitamins. Vitamin D is also important but is included in the group of fat-soluble vitamins, emphasizing the comprehensive need for A, D, E, and K collectively.
