No, and it wold probably make things worse if this is true. Tryptophan is turned into NAD but if you do not have enough of the cofactors to make NAD down the Kynurenine pathway then you will just deplete yourself of cofactors even further. I do not think depletion of NAD is the the issue honestly, but if it is the real issue is a B2 or B6 deficiency after infection. https://www.researchgate.net/profile/Fiammetta-Verni/publication/341592342/figure/fig2/AS:894263525122049@1590220447284/Tryptophan-metabolism-via-the-kynurenine-pathway-IDO-indoleamine-2-3-dioxygenase-TDO.png https://www.researchgate.net/profile/Fiammetta-Verni/publica...
