COMPOSURE™ PRO features a powerful blend of active ingredients that work together to support behavioral, cognitive and brain function and promote calm behaviour during stressful periods such as when the pet’s routine or living environment is altered:

COMPOSURE™ PRO is easily absorbed, so it does not require a loading dose to see positive results.

Composure Pro to help with Pet Behaviour

COMPOSURE™ PRO contains:

  • Colostrum Calming Complex® (C3) – A patented mixture of bioactive proteins that contains proline-rich proteins, special monosaccharides, and specific fatty acids that support brain function, relaxed behaviour, and cognitive function. C3’s effectiveness in dogs and cats may be due in part to its ability to promote the effect of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits brain activity.
  • Suntheanine® L-Theanine – A synthetic duplicate of a naturally occurring amino acid that supports normal chemical balance in the brain, thereby promoting a calming effect. Supports the release of dopamine and serotonin, which are neuromodulators, and GABA (an inhibitory neurotransmitter).
  • L-Tryptophan – An essential amino acid and the sole precursor of serotonin. Supports the release of nervous system messengers, especially those related to relaxation, restfulness, and sleep.
  • Thiamine (Vitamin B1) – Beneficially affects the central nervous system by promoting relaxed behavior in pets. Promotes normal circulation, helps to optimize normal brain function, and supports normal energy levels.
