The whole problem with this article is that the author starts off with no understanding of Vitamin D3's cofactors.
The reason D3 can be used as a rat poison is because it depletes the rats' vitamin K2 levels, which then triggers hypercalcemia. If you added vitamin K2 to the rat poison, it would no longer be a poison—in fact, it would make the rats healthier. Yes, it also depletes magnesium. And if someone experiences negative effects from taking a high dose of D3 immediately, it is always due to triggering symptoms of magnesium deficiency. At very high doses that some humans take—like 100,000 to 300,000 IUs per day—it usually takes about 4 to 6 months to trigger a toxic vitamin K2 deficiency, leading to hypercalcemia. After even longer periods of high-dose D3, you eventually get induction of boron and zinc deficiencies, as well as vitamin A. These are all cofactors that D3 uses up in its processes. In fact, there is no such thing as vitamin D3 toxicity—that is just an old doctor’s tale. What you are really seeing are just various cofactor deficiencies induced by high-dose D3 consuming them. D3 itself is completely non-toxic. The author would be better off if he would spend some time reading the book "The Miraculous Cure for and Prevention of All Diseases—What Doctors Never Learned."

D is the most important wonder vitamin, and we have substantial backing for this.
