I 100% agree with what ChrisB said.
If vitamins don't work, why do medical doctors prescribe them when someone is vitamin deficient? Hmmm.
It's true, cheap vitamins are often not absorbed. If people checked their feces, more often than not they'd find a big old Centrum tablet in them.
Also, people's absorption is pretty crappy, part of the problem we're having with our water is that people aren't absorbing their medication and entire pills are finding their way into our water supply!!! These traces amount of rx drugs are extremely hazardous to our health, which is why distilled water is so great!!!
Also, it sounds to me like the pharmaceutical companies are trying to do damage to the nutrition industry. I know here in Canada that they are trying to get an nutritions regulated, which means unless you don't spend considerable amount of money to get your product tested, you can't sell it. Good bye mom and pop businesses.
