Mind you, what was previously (and mostly still is!) considered “high doses” of vitamim D are actually closer to the RDI than the doses anyone is taking. The RDI for vitamin D was miscalculated as 1/10th its proper value decades ago, and this error was only recently corrected: https://www.sciencedaily.com/releases/2015/03/150317122458.h...
So when a science journalist—or even most scientists still—say “high doses” of vitamin D, they really mean proper doses of vitamin D. Including in this article! They’re quoting the same improper 600IU RDI standard that the article above refutes, and quoting 4000IU as an abnormal amount rather than being perfectly-well-within the correct RDI value.
