Between August 2024 and April 2025, 22 of the highest selling consumer products labeled as containing NAD+ were purchased from Amazon, and analyzed for NAD+ content by Niagen Bioscience. Here are the results:

  • 23% of the products tested (5 of 22 products) met or exceeded the NAD+ label claim;
  • 23% (5 products) had NAD+ content well below the label claim (1-89% of label claim);
  • 55% (12 products) had less than 1% of label claim NAD+ present. Eleven of these products had no detectable levels of NAD+

These results highlight the overall poor quality of NAD+ products available on Amazon.
