2. 50% of UK adults are vitamin D deficient. (3)

3. Vitamin D production is optimal at midday, so the shorter your shadow, the more you make (relative to your height of course). (4)

4. In summer, two or three 20-30 minute exposures of mid-day sunlight/week is enough in the UK. (3)

5. You make less vitamin D from the sun the greater;
your skin is pigmented (if could take 15mins for fair skin, compared to 2 hours for dark)
your age
your BMI
your distance from the equator (3,5)
