Where they even conceptually misfire in this article: it is pointless to take extra VitD "for the occasion", be it shot or travel or whatever. Key science that made me start with large daily doses of it in 2002 is that what matters is long term high level of VitD in blood, took me 9 months to achieve it, then it stays as a new norm. Keep it over 50ng/ml, easy blood test.
