Do you buy supplements? I do, and I used to buy a lot more until I recently read a little bit about the industry. The more I read the more it felt like one of those holiday scams; you know, “Oh no Sir, this is real ruby, special price for you”, he said holding up the orange piece of glass, or “We powdered the saffron to preserve it and so you have more,” he said holding a vial, the contents of which smelt like sawdust shavings. 

Only, those scams seem to have a modicum more honesty...
