12 Surprising Pros and Cons of Vitamin D Supplements

8. Vitamin D and Skin Health: Beyond the Sun

Vitamin D is synthesized in the skin in response to sunlight, but it also plays a role in skin health beyond its synthesis. It is involved in skin cell growth, repair, and metabolism, and has been used in the treatment of conditions like psoriasis. While sun exposure is a natural source of vitamin D, excessive exposure can lead to skin damage and increase the risk of skin cancer. Supplements offer a way to obtain vitamin D without these risks, but they should be used judiciously, considering individual skin health needs and potential interactions with other treatments.
