That link didn't work for me, but thanks for including it.
Might be too much time has elapsed or simply my connection here.
Consumer reports are also available for an annual fee, you can subscribe to their magazine or get to their info online.
Or you can go to your public library to check it out. They do quality control on a variety of household products.
As far as vitamins are concerned their rubric is making sure the vitamins dissolve in a 30 minute period of time, are free from impurities,contain what they're supposed to contain, and are at the potency on the label.
One way to assure that your supplement is the correct potency is to see if its tested by an independent lab. Best known are USP (United States Pharmacopeia) or GMP(Good Manufacturing Practices) labels.
As far as I know, Consumer Labs doesn't get into whether or not a supplement is worth taking.... for that you'll have to go the the Examine.com site.
Thx everyone for reading and contributing.
