Back a couple decades ago I was working for a contractor and was bidding a job at a sewage treatment plant.
The white hat (maintenance boss there) took me for a quick toor. he showed me the skimmers and what was skimmed off the raw poopies that came into the place.
Of interest was the thousands and thousands of vitamins caught in the screens. He told me that lots of the fancier vitamins do not disolve in the digestive system and end up in the treatment plant.
Seemed like a huge waste of money to me so I haven't taken any vitamins since.

Granted not all vitamins pass straight through, some actually work. But how do you tell which ones?
