Vitamin D and Sunlight: Are We Getting Enough?
How the body makes vitamin D from sunlight, which foods contain it, and what to know before taking supplements.
Why This Guide Matters
Step-by-step Implementation:
How sunlight makes vitamin D
When UVB rays from the sun hit your skin, the body produces vitamin D. It helps absorb calcium, which keeps bones and teeth strong.
It is not the same for everyone
Skin colour, season, time of day, how much skin is exposed, and sunscreen all matter. Darker skin makes vitamin D more slowly. So no single 'minutes per day' rule fits everybody.
Food and supplements
Oily fish, egg yolks and fortified foods contain vitamin D. If you suspect a shortfall, get a blood test and talk to a doctor before taking supplements, because too much can be harmful.
