"Sunshine and Your HealthIf one regularly avoids sunlight exposure, research indicates a necessity to supplement with at least 5,000 units (IU) of vitamin D daily. To obtain this amount from milk one would need to consume 50 glasses. With a multivitamin more than 10 tablets would be necessary. Neither is advisable.
The skin produces approximately 20,000 IU vitamin D in response 20–30 minutes summer sun exposure—100 times more than the US government's recommendation of 200 IU per day!
There are 3 ways for adults to insure adequate levels of vitamin D:
regularly receive midday sun exposure in the late spring, summer, and early fall, exposing as much of the skin as possible.
regularly use a sun bed (avoiding sunburn) during the colder months.
take 5,000 IU per day for three months, then obtain a 25-hydroxyvitamin D test. Adjust your dosage so that blood levels are between 50–80 ng/mL (or 125–200 nM/L) year around.
