If you cook or grow your own food (microgreens, mushroom in a kitchen cabinet), there are alternatives.

For example: https://www.milkwood.net/2014/03/31/want-extra-vitamin-d-pla...

This works for both shiitake and button (portobello) mushrooms.

This trick came from Paul Stamets, one of the world’s foremost mycologist. He is based out in Casscadia. You may have to track down exactly what “2 days” means... I wouldn’t be surprised if he went looking for a way to maintain his Vitamin D health.

You only need 10g of this four times a week, according to this article. While it is summer time in Seattle, you can prepare a bunch and then dry them, so they last until next spring.

This is a great insight, thank you.
