Decreased urinary output of conjugated tyramine is associated with lifetime vulnerability to depressive illness

Psychiatry Res. 1980 Sep;3(1):13-21. doi: 10.1016/0165-1781(80)90043-8.

Abstract

In a group of normal pregnant women whose psychiatric histories were unknown, those with the lowest output of urinary tyramine (free plus conjugated) after an oral tyramine load had a significantly higher lifetime incidence of depressive illness compared with those with the highest output. as none of the women were suffering from depression at the time of tyramine loading, it seems likely that this decreased excretion of tyramine is associated in some way with vulnerability to depressive illness, whether puerperal or nonpuerperal.
