Answer a few questions about sun exposure, diet and lifestyle. The checker estimates your risk level and gives practical, safe tips to raise your vitamin D.
1. How much direct midday sun do you get on most days?
2. When you are outside, how much skin is usually exposed?
3. What is your skin tone?
4. Do you use sunscreen when going out in the day?
5. How often do you eat vitamin D foods (oily fish, eggs, liver, fortified milk)?
6. What is your age group?
7. What best describes your daily routine?
8. Do you often have any of these: bone or muscle pain, tiredness, frequent illness, low mood in winter?

Note: This checker estimates risk from lifestyle answers only — it is not a medical diagnosis. Only a blood test (25-OH vitamin D) can confirm a deficiency. If you have symptoms like bone pain or constant fatigue, see a doctor. Do not take high-dose vitamin D supplements without medical advice, since very high doses can be harmful.
