Consumer Verification Guides
Readers often ask which brand is best or which products make the top ten. JHFC does not publish brand rankings or recommend specific products. These guides set out checks readers can carry out themselves: the daily amount on the label, whether a test report matches the batch, the manufacturing site and raw material sources, and how labels differ between import channels. The standards cited in each guide are listed under Standards.
This section covers information verification methods only; it does not evaluate the efficacy or safety of any ingredient.
