> Taking 60,000 international units (IU) a day of vitamin D for several months has been shown to cause toxicity. This level is many times higher than the U.S. Recommended Dietary Allowance (RDA) for most adults of 600 IU of vitamin D a day.

Well of course, drinking 100x times the recommended amount of water would be even worse.

A 50,000 IU pill is smaller than a pinto bean. I'm not saying to not take vitamin D, but it can be overdosed with serious negative side effects and the best way to not do that is to consult your physician.

Where did you find 50k pills? I'd like to get some...

Most I find anywhere are 5k, and I'm the only one I know that buys them. In a supremajority of cases 50k daily would mean... let's see... about 10 fistfulls of pills. It takes dedication to swallow that much every day.

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.
