Vitamin D Calculator
Vitamin D deficiency is very common in New England. Low vitamin D is linked to depression, colon cancer, diabetes, heart disease, and osteoporosis. Laboratories commonly report levels of <20 ng/ml as deficiency and between 20-30 ng/ml as insufficiency. If your levels are at least 40-50 ng/ml, you are in good shape. Our body can make more than adequate levels of vitamin D when exposed to enough sunlight. The time of day, season, and other factors influence vitamin D production. Dark skinned people need more sunlight than light skinned people to make the same amount of vitamin D. You can get too much vitamin D from supplements. That is why it is best to have your levels monitored by a professional.
This helpful online tool will help you to determine how many minutes of exposure to sunlight that you need in order to make 1000 iu of vitamin D.
VITAMIN D CALCULATOR
You must enter the following info to get accurate results:
1. Time and location
2. City, latitude and longtitude
* This is available on Google Earth or from a GPS device. Latitudes need to be entered as North and longtitudes need to be entered as East, therefore if your latitude is 39 South, that would be entered as -39. If your longtitude is 79 West, enter -76. Otherwise the number is positive. Hartford, CT would be entered 41.45 and -72.41.
3. Skin Type
4. Time of day
* Must be converted to Greenwich Mean, or you can just choose "mid-day".
5. Sky condition
6. Ozone layer thickness
*Choose medium, unless you have more detailed information available.
7. Surface altitude and surface type
*Elevation must be entered in kilometers. Hartford elevation is 69 ft, entered 0.021 km
For example, on a dry, cloudless day at noon in late January in Hartford, CT, it would take 36 minutes to produce 1000 iu (or 25 mcg) of Vitamin D. Pretty cool.
