took orally administered n R or n MN both precursors to nad and it showed that the liver could take those up in significant quantities combine them with tryptophan and make lots of intrahepatic nad but none of it made it into the cell so the NAD doesn't make it into the cell and the N R and the n MN we're not being taken up by cells other than hepatocytes
