Consumer Verification Guides
Readers often ask whether NMN really works or whether stem cell treatment in Japan is legitimate. JRQ does not evaluate efficacy and does not recommend products or medical providers. These guides set out checks readers can carry out themselves. The JRQ standards cited in each guide are listed under Standards (in Japanese).
This section covers information verification methods only; it does not evaluate the efficacy or safety of any ingredient or treatment.
