But, but, my pee is full of Vitamin C and other nutrients so I should drink it to improve my health. Right?

Last year, my doctor said I have very low vitamin D since I don't go outside under the sun so I have to take 4 NatureMade D3 1000 IU softgels.

What he meant is that you need vitamin C too.

Kind of glossed over some things. Yes, in many cases vitamin supplements are only needed if you have a poor diet or other condition interfering with your required levels. Yes, Vitamin C is not going to cure a cold.

But, there are still studies being done that show it 'might' have a long term effect on cancer if you get your minimum daily requirement. There are also studies being done on other vitamin usage for long term disease factors.

So, while you really don't want or need to overdose yourself with vitamin supplements, it doesn't hurt to make sure you are getting the proper amount daily either by eating healthy or taking a supplement to fill in what you do need.

Then again, it is the tagline that he ruins stuff, so I can see why he would leave it a bit vague for comedy.

He is attacking people's belief in the mythic powers of vitamins, not necessarily the need for them.

I think it would be hard to find a control group of modern people who *don't* get the "proper daily amount" of most vitamins; or at least the "proper daily amount" times 7 each week. Ie., maybe there are people who live off of hot pockets and potato chips for a few days at a time, but eventually they are going to go out and eat something that coincidentally contains plenty of the vitamins to cover for the days that they were eating the modern equivalent of hardtack.

Not that it couldn't be done, and not that the results wouldn't be interesting -- maybe getting trace amounts of vitamins daily really would have better long-term health effects than getting larger amounts of vitamins every few days or once a week. But it would be *really* hard to accurately pare down a study to that single variable.
