QUESTION: Which vitamin we get from sun?
ANSWER:
- We get Vitamin D from exposure to sunlight.
- When our skin is exposed to the ultraviolet B (UVB) rays in sunlight, a type of cholesterol in our skin cells is converted into vitamin D3.
- This form of vitamin D then undergoes further conversion in the liver and kidneys to become active vitamin D, also known as calcitriol.
- It is recommended to spend a brief period of time in the sun each day without sunscreen, typically around 10 to 15 minutes for fair-skinned individuals.
- The amount of time needed can vary depending on factors such as
- Skin type
- Geographic location
- Time of year
- Personal circumstances
