Vitamin D

A fat-soluble vitamin called vitamin D is essential for numerous bodily functions, including the health of your skin. The bulk of the epidermis, or top layer of skin, is made up of skin cells called keratinocytes. The only cells in your body that can convert vitamin D from its precursor 7-Dehydrocholesterol (7-DHC) into a form that your body can utilize are called keratinocytes. Vitamin D is essential for the health of the skin immune system, which serves as the first line of protection against hazardous microorganisms, as well as the function of the skin barrier and skin cell proliferation.

Low blood levels of vitamin D have been linked to a number of skin disorders, including eczema and psoriasis, both of which can result in dry skin, according to some studies. Additionally, vitamin D supplements have been demonstrated to greatly lessen the signs and symptoms of skin conditions like eczema that lead to dry, itchy skin. Additionally, studies have shown a connection between vitamin D and skin hydration. In a study including 83 women, it was discovered that low vitamin D levels were associated with lower average skin moisture than individuals with normal vitamin D levels. Additionally, when vitamin D levels rose in the blood, skin moisture content rose as well.

Another short 12-week trial on 50 women found that daily use of a vitamin D dietary supplement with 600 IU significantly increased skin moisture. It's uncertain if therapy with vitamin D alone would have had the same beneficial effect, though, because the supplement contains a variety of minerals. Vitamin D deficiency affects a big portion of the population, and as the vitamin is necessary for hydrating the skin, taking supplements may help prevent dry skin. To guarantee the best quality, search for products that have undergone third-party testing, and be sure to discuss the usage of vitamin D supplements with your doctor.
