And the "baseline level" of vitamin D (25-OH-D) at the start of beginning UVR/supplement therapy must be taken into consideration.

Finally, multiply the results (calculated by the calculator) by two (to compensate for the fact that sunlight can only strike one side of the body at a time) and you will be "much closer" to the truth.
