How long does a product last when its been open (as in freshness). I have a bottle of milk thistle here which I opend around 10 months ago while taking a product but discontinued its use. I also have some other supplements and vitamins that I did not finish using. Just wondering if they are still good to use. They were stored in a dark cool place, cabinet.
Forgot to add, the milk thistle expires on 10/2010 along with the others.
