Best way to fix this, about five to ten minutes in the sun each day.
That’s it. It’s not a big threat of skin cancer, and it replenishes Vitamin D in a matter of days.

I agree but will add that the time of day may be important, between 10 AM to 2 PM is optimal...or so I've heard.
It’s more difficult for seniors to convert sunlight to Filament D so supplementation advised.
Well, that might work during the summer.
But sadly, during the winter months, even at somewhat good latitudes like CA, the sun is simply too far south of the zenith to work.
Make in 15-20 minutes in the sun, most of the year this would have to be in the middle of the day, and you can’t have a shirt on. I know so one who gets “his” vitamin D that way, by doing interval running without his shirt on his lunch hour, but some of us would have a hard time with that (especially girls) so we supplement.
You can test how high your D gets in the bloodstream and do some sun, some supplementation. You need it at least 60 especially in winter to fight flus etc. High enough D plus enough sleep, you won’t get sick.
For the rest of us not so much.
There are cities that have no sunshine for many days, sometimes for a whole week or more, especially in winter. Bodies of water are often the culprit.
