10 ng averge for 87 men and 52 women who were 30 years old
They claimed that 68% of the people tested were getting enough vitamin D from the sun
80 minutes a week of sun on forearms and legs from 9AM to noon
80 minutes per week for people with skin color of 3 (range of 1 = white to 7 = black) at latitude = 30 degrees North
would be about 1100 IU daily
The body consumes 2300 IU of vitamin D daily
- 1100 IU would not be enough vitamin D to replentish the 2300 IU consumed daily

- Also: urban haze reduces the amount of vitamin D actually getting to the ground.
