Juxtaposing with the quoted passage from the post: “Because vitamin D is potentially toxic, intake of [1000 IU/day] has been avoided even though the weight of evidence shows that the currently accepted [limit] of [2000 IU/day] is too low by at least 5-fold.” --https://www.sciencedirect.com/science/article/pii/S000291652...
