Yes, this is true and worth mentioning in some cases, as some commenters have noted. Although as far as my knowledge goes, almost all cases of issues are where the patient is taking either an absurd amount (>10x what they should be), or has some other very unusual/absurd health issue. We can only provide disclaimers for so much, but for the sake of completeness, this is worth mentioning and indeed correct.

Too much Vitamin D without sufficient Vitamin K can lead to high levels of serum calcium that are not absorbed into the bones. One function of Vitamin K is to shuttle calcium into the bones. You can often purchase combined Vitamin D and Vitamin K supplements to avoid those issues.
This isn't true--especially for Vitamin D. We have several doctors at this point who deal with cases where too much Vitamin D causes Calcium uptake issues and affects cognition and heart function.
Vitamin D is NOT something like Vitamin C. Your body easily dumps excessive Vitamin C so you can take fairly massive doses with no real ill effects.
Your body has a much tougher time excreting Vitamin D--so large doses of Vitamin D can cause issues and accumulate.
