When to Test?

Ideally you want to know what your vitamin D level is after sun exposure, and after little or no sun exposure. 

Many experts recommend testing twice a year - at the end of winter (March) for the lowest levels, and again at the end of August to see levels at their highest.   If you supplement with vitamin D, any time of year is a good time to test, but if you have recently changed your dose of vitamin D, wait at least 4 weeks before testing.
