Excellent analysis! I have been a vitamin D3 proponent for several years and have noted that I no longer get severe respiratory infections like I used to. I would argue that the “adequate” levels between 20 and 30 are actually inadequate. This chart shows that the optimum levels for disease prevention are between 40 and 60. (My D3 level typically ranges from mid 50s to 70.)
