No, it’s not free, but $19 a year is not a lot to pay for reliable information about the effectiveness and dangers, of 14,000 natural supplements. The database, compiled by the Therapeutic Research Center in Stockton, California and sold by Consumer Reports, gets high praise in this piece in the Washington Post, which links to two similar databases built by the National Institutes of Health. One of those comes out of NIH’s Office of Dietary Supplements and one comes from its National Center for Complementary and Alternative Medicine. All good stuff.
