L-Tryptophan for Dogs With Anxiety

Tryptophan deficiencies have been implicated as a cause for increased anxiety and aggression in dogs. Supplementing diet with L-Tryptophan is a natural way of reducing those feelings of anxiety, improving your dog's behavior.

  1. Function

    • Tryptophan is a neutral amino acid that exists naturally in your dog's body and is essential in small amounts for a healthy diet. It aids in healthy digestion and serves as the precursor to serotonin, a neurotransmitter associated with healthy, calm emotions and self-control.

    History

    • L-Tryptophan was banned as a dietary additive for humans in 1989 after a contaminated batch from Japan caused illness. However, it is still available with other supplements for pet use.

    Effects

    • Studies show that dogs with tryptophan deficiencies are more likely to show aggression, depression and moodiness. Thus, dogs that show signs of aggression or anxiety are often treated with L-Tryptophan, which reduces aggression and increases calm behavior.

    Benefits

    • Many medications for anxious dogs cause liver and kidney damage when long-term use is necessary. Since L-Tryptophan is a natural amino acid, it can improve your dog's behavior without concern of organ damage.

    Warning

    • L-Tryptophan should not be administered without veterinary approval because it can react with some medications and cause side effects such as vomiting and diarrhea.
