Which vitamin is absorbed through sun exposure?

The vitamin that is absorbed through sun exposure is Vitamin D. This essential nutrient is unique because, unlike most vitamins that must be obtained from dietary sources, the body can synthesize Vitamin D when the skin is exposed to ultraviolet (UV) rays from sunlight.

When UV rays penetrate the skin, they trigger a chemical reaction that converts a cholesterol derivative in the skin into Vitamin D3. This form of Vitamin D is then further metabolized into its active form, which plays a crucial role in calcium absorption, bone health, immune system function, and overall well-being. Therefore, adequate sunlight exposure is important for maintaining optimal Vitamin D levels in the body.

Other vitamins like A, C, and E have different sources and are not synthesized through sun exposure, which makes Vitamin D distinct in this regard.
