Abstract in brief
- Ultraviolet B radiation from sunlight is responsible for over 90% of vitamin D production in most people, and there are concerns that using high-SPF sunscreens might block this process, leading to vitamin D deficiency.
- The article reviews scientific studies that both support and question the idea that sunscreen use causes vitamin D insufficiency, considering experimental conditions and real-world usage.
- The conclusion is that while sunscreens can significantly decrease vitamin D synthesis in controlled settings, normal everyday use of sunscreen typically does not lead to vitamin D deficiency.]

But in reality, most people applied way less than the recommended amount & not really applied on every parts & every inch of the body (scalp, leg, etc.). There're many ways of getting vitamin D other than exposing your skin to UVB. https://t.co/LGaYLouFio
