L-Tryptophan Supplement -100mg capsules (40 capsules)

L-Tryptophan is an amino acid (protein) and can have a calming effect in cats. It is converted in the body to serotonin often called “the happy hormone”. Studies have shown that supplementation of L-Tryptophan can reduce anxious behaviour in cats.

What does Anxiety in cats look like and what causes it?
If your cat has anxiety, you may notice -

  • pacing or restlessness
  • hiding, decreased appetite
  • excessive grooming
  • vocalization
  • hyper-vigilance
  • trembling
  • salivation

You should always check with your vet first to rule out medical problems. However some feline anxiety is due to their environment, some of which can be alleviated, for example making sure their is enough food, beds and litter trays but others can not, for example living in a multi-cat household.

L-Tryptophan supplementation may help calm your cat
L-Tryptophan is naturally found in red meat, poultry, eggs, and dairy. L-tryptophan is important for many organs in the body. L-tryptophan is not made by the body and must be consumed from the diet. After absorbing L-tryptophan from food, the body converts some of it to 5-HTP and then to serotonin. Serotonin is a hormone that transmits signals between nerve cells. Changes in serotonin levels in the brain can affect mood.
