One wonders why this claim is being made. It is easy to demonize Big Pharma (I'll be first in line) but there seems to be no corresponding skepticism about the motives of supplement manufacturers - and supplements are a multi-billion dollar (euro, etc.) business.

From Snopes "It [the codex] has no power to force its will on any nation. Codex standards are voluntary, which means if the U.S. doesn't adopt them, they will not govern the regulation of vitamins, minerals, or dietary supplements in the USA."

I think that some supplement manufacturers are spreading these false rumors about the Codex because they want no regulation of their products whatsoever - not even for safety, purity, etc. It costs money to make sure your products are pure, manufactured safely, etc. There are more profits to be made by just packaging whatever into gel caplets and selling it for exorbitant amounts of money.

These are exactly the same rumors that were spread by the lobbyists (and they spent millions on the lobbying) for the supplement manufacturers that resulted in the FDA being stripped of any power to take action against disreputable supplement manufacturers - regardless of what they were packaging and selling - until after consumers have been killed or maimed by their products. And even then, it is very difficult to get dangerous products off of the market.

For those of us who want to buy safe, pure supplements made by manufacturers who take care that their products are uncontaminated and contain what they say they do - this misinformation is not the way to go.
