Which supplement can be used to manage the effects of corticosteroids on wound healing?

1. Magnesium

2. Vitamin D

3. Vitamin A

4. Calcium

The correct answer is: Vitamin A

Vitamin A plays a critical role in wound healing and is particularly beneficial for individuals who are on corticosteroid therapy. Corticosteroids can impair the body's inflammatory response, which is essential for healing processes. Vitamin A is known to enhance epithelialization (the formation of new skin) and play a pivotal role in cellular growth and differentiation, thus aiding in re-epithelialization over wounds. Additionally, Vitamin A has been shown to support the immune system and mitigate some of the adverse effects that corticosteroids may have on inflammation and tissue repair. Its ability to promote collagen synthesis and tissue regeneration is vital for effective wound healing, especially in patients whose healing processes are compromised due to corticosteroid use. While other supplements like magnesium, calcium, and vitamin D have roles in various physiological processes, their direct impact on enhancing wound healing in the context of corticosteroid therapy is less pronounced compared to the established benefits of vitamin A.
