Ignacio Rojas Ru\'iz (Comp.), ISBN: 978-84-16929-58-0 (2017), 27, 2017 The synthesis of vitamin D is strongly linked to the availability of solar energy. For a long time, it was clear that using the erythemal irradiances is a good choice to calculate the exposure time. Several authors argue that this method of minimum exposure time overestimates the calculation of the solar irradiance of vitamin D.
