 This seems logical, but isn't always true.  Many nutritional supplements do 
not have noticeable signs of performance (good or bad) so the user isn't 
aware if the product is any good.  I am the quality assurance manager of a 
pharmaceutical testing lab.  There are "official" tests for many herbal and 
all vitamins and minerals.  To make sure a product meets the requirements of 
the United States Pharmacopoeia, it should read USP after the name of the 
ingredient on the label.  Most vitamins must be within 90 to 200% of what the 
label says.  Most minerals the same.  Exceptions are iron and folic acid, 
which have tighter specifications.  If it says USP after the name (on the 
label or on the ingredient list) then it is likely the product is tested for 
purity and potency.
