Yeah I think it may be a bit overzealous to say that even people who are not supplementing at all, and even in a population where low Vitamin D is common, should wait until they measure k and Vitamin D (which could be not for a long time). “first, do no harm” seems to be the thread of this caution though, so not exactly unexpected from a doctor.
