i first starting taking vitamin D as a preventative for covid back in 2020 (i never got the kung flu vax) then did more research and found out it helps prevent a lot of disease/illness...
K2+D3 is what I take ... as for zinc, you’re not supposed to chew on the container of your favorite drink ...

Same here. Still taking a 5,000iu D3 pill a day, along with a vitamin K-2 pill. Plus, there’s some D3 in other supplements I take.
I don’t know if it helps. I suppose it would be hard to prove one way or another.
