Calming supplements can play a supportive role in managing noise sensitivity, but they're most effective when paired with environmental changes and gradual exposure training. They don't sedate your dog or block the fear response entirely - instead, they may help lower baseline anxiety, and also make room for training to become more effective.
How they work
Supplements typically contain ingredients that interact with the brain's natural calming systems:
- L-tryptophan - a building block for serotonin, the neurotransmitter involved in mood regulation
- Passion Flower - supports GABA activity, which helps reduce nervous system excitability
- B vitamins - contribute to normal nervous system function, which often get depleted during stress
- L-tyrosine - a precursor to dopamine to support mental resilience
These work gradually over days to weeks.
Setting realistic expectations
Supplements won't eliminate noise phobias on their own. A dog who panics at fireworks will still react, but may recover faster or show less intense distress. They're most useful for dogs with mild to moderate sensitivity, or as part of a wider plan that includes sound desensitisation, safe spaces, and predictable routines.
Start supplements several weeks before expected trigger events (fireworks season, storm season) rather than using them reactively on the day.
