50k is a one time thing, you shouldn't take this everyday! Read other comments there are articles about the toxicity of 60k per day leading to kidney failures.

I would never take more than 10k daily, and even that might be too much. I really need to have my blood tested.

Here in France when doctors prescribe vitamin D it's a one time thing, say for 3 months. It's in liquid form and comes in a small glass tube.

It's either 50 or 100k.

I was mostly joking. I rarely take as much - only when I have a bad flu or the beginning of one. And it's included in the yearly checkup: I'm either deficient or, since I started supplementing seriously, normal.

In the US, I was prescribed weekly 50kIU pills. They were the same size as my current 2k doses.

I think it looked something like this [0]. Curiously it was much cheaper than my supplements after insurance and was like $0 or $5.
