I ain't no doctor (not a medical one, anyway), but I've always thought the best was to get vitamin D was to allow the body to convert cholesterol into it by getting 15-30 minutes of mid-day sun exposure outside 4-5 times a week. Of course, that isn't always possible for many of us, especially those of us who live in areas that don't get a lot of sun. But if possible, it still seems like a good plan. One study found just 30 minutes of mid-day sun exposure was equal to consuming 10k-20k ui of vitamin D, which comes out to the same amount those docs are taking for the initial dose, so more than enough without supplementation: https://www.healthline.com/nutrition/vitamin-d-from-sun
Of course, you have to be careful not to overdue it--you don't want to burn your skin, but mid-day sun seems to be the most efficient way, and the risk of skin cancer from moderate mid-day sun exposure seems pretty low and worth the trade off--those times you cook and burn are what really up your risk.
