Early in 2008, I did a few blogs about food shortages and also plans to outlaw the sale of vitamin supplements and make small (home) scale food production very inconvenient.
As supplements are classified as FOOD, you can currently buy as much of them as you want. Once they become classified as TOXINS or "controlled" substances , then their sale becomes subject to gov't permit. To see how well that works, look no further than people who have gotten arrested for buying "too much" allergy & cold medicine (Gary Schinagel, for example - www.globegazette.com/articles/2008/09/23/news/local/doc48d877436e870927909116.txt ) - That hissing sound you hear is Libs wetting their beds defending the "i n t e n t i o n" of the law. Results don't matter, just "i n t e n t i o n".
Back to B6. The FDA was petitioned to ban the sale of B6 based on it being similar to a drug -- developed from, you guessed it, B6. Here is one of the many articles about it you didn't hear from the lame-stream-media: www.naturalnews.com/023514.html
But, hey, what do I know? I just make it all up and draw paranoid conclusions. Not to worry... except, there is that little matter of finding the actual petition. Check the PDF.
