Well I guess my thought process (however incorrect it might be) is that from a food safety perspective--not necessarily a supplement efficacy perspective--there's a greater bar to pass for the FDA to allow something to sit on the shelf at CVS than to get it from some random vendor on Amazon that might not even reside in the US.
I see. The fact is, the FDA doesn't regulate what's in supplements so it could be grass in those pills whether they come from Utah or Uttar Pradesh.
As for food safety, the standards are the same whether manufactured in the US or outside. The FDA ensures they comply with HARPC and are made in cGMP facilities.
