L-Tryptophan for Horses
L-Tryptophan is an essential amino acid and a precursor to serotonin, a neurotransmitter involved in mood regulation. In horses, it’s commonly used to support calm behavior and stress management.
Why It’s Used
Calming Support
May help:
Nervous or reactive horses
Stress during transport
Adjustment to new environments
Mild pre-event tension (non-competition use unless rules allow)
It is not a sedative — effects are usually mild and supportive.
Mood & Behavior Balance
By supporting serotonin production, L-tryptophan may:
Reduce excitability
Improve focus
Support training responsiveness
Results vary between horses.
