Vitamin D and Atopic Dermatitis
Atopic dermatitis (AD) is a chronic inflammatory skin disorder that is characterized by dry, itchy and scaly skin. It is estimated that 30–60% of the world's population has the disorder. Vitamin D is a fat-soluble vitamin that plays a role in calcium and phosphorus homeostasis, cell differentiation, and immunity. Recent research suggests that vitamin D may have a beneficial effect on AD, but the evidence is still inconclusive. In this article, we will discuss the potential role of vitamin D in the treatment of AD.
What Is Vitamin D?
Vitamin D is a fat-soluble vitamin that is essential for the proper absorption of calcium and phosphorus, which are important for healthy bones and teeth. It is also involved in cell differentiation and immunity. Vitamin D is produced in the skin in response to sunlight exposure, and it can also be obtained from certain foods, including fish, eggs, and fortified dairy products.
How Could Vitamin D Help with Atopic Dermatitis?
Recent studies suggest that vitamin D may have a beneficial effect on AD, but more research is needed to confirm these findings. One possible mechanism is that vitamin D may help modulate the immune system and reduce inflammation, which could help reduce the severity of AD symptoms. Additionally, vitamin D may help reduce the production of inflammatory chemicals called cytokines, which are believed to be involved in the development of AD.
What Are the Recommended Levels of Vitamin D Intake?
The recommended daily intake of vitamin D varies depending on age and other factors. For adults, the recommended daily intake of vitamin D is 600 IU (international units) for people aged 19 to 70 years, and 800 IU for those over 70. It is important to note that excessive intake of vitamin D can be toxic, so it is important to speak to a doctor or health care provider before taking a vitamin D supplement.
Conclusion
Atopic dermatitis is a chronic inflammatory skin disorder that affects a large portion of the world's population. Recent research suggests that vitamin D may have a beneficial effect on AD, but more research is needed to confirm these findings. It is important to consult with a medical professional before taking a vitamin D supplement, as excessive intake can be toxic.
