Doctor says that +75 is good, but +100 would be better since I have Osteopenia in neck and tail bone and you need Vitamin D to absorb Calcium. I take pills with Vitamin D/Calcium and eat a lot of dairy, but I'm going to have to up the Vitamin D supplements.
Slight addendum for everyone (I tried to find a more forceful source to back up what my doctor said, but the best I could find was SUNLIGHT, VITAMIN D AND HEALTH by Laurance Johnston, Ph.D):
"Exposure to vitamin-D-producing UVB light can vary greatly depending upon many factors, including time of day and year; and the latitude, altitude, and prevailing weather conditions of where we live.
"Latitude is especially important. For example, if you live north of about 37° (roughly, a line from Richmond to San Francisco), you will be exposed to little UVB from at least November through February because the sun’s zenith angle is so low that the atmosphere absorbs most UVB before it reaches you."
What do you guys use?
