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-round.

Is it just me, or is saying "cholecalciferol is pronounced cho·le·cal·ci·fer·ol" rather less than helpful? Dictionary.com says it's pronounced koh-luh-kal-SIF-uh-rawl.

Thanks for clipping!
A theme, I'm interested on, since my kids got those small pills in their first years, while I got UV-sun shining when I was a child and later I learned in school biology, that Vitamin D cannot be taken with substances and only eskimoes can build it without UV rays.
