You’re probably thinking of IUs rather than ug but even then 50k is way too much:
“Doses below 10,000 IU/day are not usually associated with toxicity, whereas doses equal to or above 50,000 IU/day for several weeks or months are frequently associated with toxic side effects including documented hyperglycemia.”
You should probably be taking like 50,000. It is very hard to absorb through the gut.
Please don’t.
Vitamin D — unlike vitamin C — is not water-soluble and you can take too much.

The Finnish authorities often changed their suggested daily amounts, but 10 and 20ug are more common and 50 is already on the higher side.
I tried taking 100ug a few years ago but I then got joint pain and think it was actually too much with my diet.
So I’ve found 50 to be good for me. I don’t get sun. Like it’s genuinely been weeks or months when I was in direct sunlight. I can’t even recall.

50,000ug is 2,000,000 IUs, in other words way too much!
