1.

D-Estimator has been designed to estimate vitamin Dblood levels. Enter all yellow fields. Zero is OK, if theanswer to the question really is zero. Estimated 25(OH)Dblood level is displayed immediately. Check Vitamin DStatus using pink table titled 25(OH)D Blood Levels.

2. D-Estimator also displays an estimate of how muchvitamin D3 you make from sunshine. Make sure you enterall your personal particulars correctly, then enter weeklyminutes of sun exposure of various kinds. Then see the bluetotal at the bottom of the Daily Vitamin D (IU) column.

3. You can also use D-Estimator to estimate how muchvitamin D3 you need to supplement. Enter all fields, as

though you were estimating your blood level, except for thequestion: Of the last 6 months, which have been warmenough ? Enter that answer as YYYYYY. Answer allquestions about sun exposure (weekly minutes) asaccurately as you can, but consider that you are telling D-Estimator how much sun you expect to be getting in thenear future, rather than how much you took in the past.

When you get to the supplement question (cell i24), anysupplement dose you enter will affect the Estimated bloodlevel. Enter different values of supplement dose until youfind one that causes the Estimated blood level to be 50ng/ml. If you take that dose of vitamin D3 as a dailysupplement, together with the amount of sun exposure youentered, you should maintain a near-optimum blood levelof vitamin D. If your sun exposure habits change (as theywill with the seasons) simply enter the changed informationand find your new estimated dose as before
