I am not a Dr (of medicine), and many of my Dr (of medicine) friends tell their patients to take Vitamin D. At one point I asked my GP, hey, why don't you tell me to take Vitamin D, you tell your patients and talk about how great it is. He looks at me and says "well, I know you run outside like every day".
Years later, I looked at my levels during some blood work and saw my D was elevated. My Dr again said "yea, you run in the sun."
Yes, it is a singular data point, but if you are inside all the time, get your D levels checked and see where you stand instead of just taking pills for it. You might be in the normal range, you might not. It is probably genetics, and how much sun you get too.
