Why there is no amount here: The trials, Bosch et al. 2009 and Kato et al. 2012, added tryptophan to the food rather than giving a daily amount per kg of body weight. On top of that, every complete food already has to contain tryptophan as a nutrient. A range here would measure whether a product is dosed like other products, not whether the amount does anything.

Why there is no amount here: No study in dogs or cats links an amount to a measured effect. What appears on labels is traditional use.
