I know what you mean about product safety ..every thing is becoming suspect... there is a independent lab that checks vitamins for active ingredients & if they have contaminants in them...

there is a fee for 1 yr. it's $27...they check vitamin E for mercury, PCB's & other contaminants...if you take a lot of vitamins or know a friend to split the yearly cost it might be worth it ..their is a 30 day fee for $10 but I'm not sure if it's for looking up just one product or more than one....
