L-Tryptophan

L-Tryptophan is an essential amino acid — one a dog can only get from their diet. The body uses it as a precursor to serotonin, which is why it features in True Calm's calm-behaviour blend.

What is L-Tryptophan?

L-Tryptophan is an essential amino acid that dogs obtain from their food. It's the raw material the body uses to produce serotonin, a neurotransmitter involved in mood and calm.

Is L-Tryptophan safe for dogs?

L-Tryptophan is commonly used in canine calming products and is well tolerated by healthy adult dogs at supplemental levels. Speak to your vet before use if your dog takes medication that affects serotonin (such as certain behavioural medications), as a precaution.

What does L-Tryptophan do for dogs?

It supports the body's own production of serotonin, helping to manage everyday stress while keeping your dog focused. In True Calm it's paired with L-Tyrosine so calm doesn't come at the cost of alertness.
