Cr. Martin et Ab. Bonner, A pilot investigation of the effect of tryptophan manipulation on the affective state of male chronic alcoholics, ALC ALCOHOL, 35(1), 2000, pp. 49-51

tophan manipulation would influence self-report affective status in alcohol
ic males. No significant effect of dietary manipulation was observed on the
tryptophan/large neutral amino acids ratio or psychological indices of aff
ect. The notion that dietary manipulation may be utilized in improving mood
state in alcoholic males was not supported.
