Always Consult Your Vet
L-Theanine (from Green Tea)
Calm focus without sedation
L-Theanine is a naturally occurring amino acid widely studied for its ability to promote relaxation while maintaining alertness. In dogs, it supports a calm mental state without causing drowsiness — making it ideal for daily use.
Why it matters:
- Helps reduce stress and anxious behaviours
- Supports focus and emotional balance
- Non-sedating and well tolerated
Scientific backing:
Strong evidence from veterinary and human research supports L-Theanine's role in regulating stress responses via neurotransmitter activity.
L-Tryptophan
Supports serotonin — the "feel-good" pathway
L-Tryptophan is an essential amino acid and a natural precursor to serotonin, a neurotransmitter closely linked to mood stability and emotional regulation.
Why it matters:
- Helps promote a calmer, more settled mood
- Supports relaxation during periods of stress
- Plays a role in healthy sleep-wake balance
Scientific backing:
Well-established research links L-Tryptophan to behavioural calm and stress moderation in dogs when used appropriately.
Lemon Balm (Melissa officinalis)
Gentle botanical calm, backed by tradition and science
Lemon Balm is a calming herb with a long history of use for nervous tension and restlessness. Modern studies support its role in soothing the nervous system and promoting relaxation without sedation.
Why it matters:
- Helps ease nervousness and agitation
- Supports emotional comfort in unfamiliar or stressful situations
- Gentle, plant-based support
Scientific backing:
Supported by growing evidence in both veterinary and human research for its calming and anxiolytic properties.
Thiamine (Vitamin B1)
Foundational support for the nervous system
Thiamine is an essential B-vitamin crucial for normal nerve function and stress response. Deficiency has been associated with increased sensitivity to stress and noise in dogs.
Why it matters:
- Supports healthy nervous-system signalling
- Helps dogs cope better with environmental stressors
- Extremely safe and well tolerated
Scientific backing:
Strong nutritional science supports Thiamine's role in neurological health and stress resilience.
How These Ingredients Work Together
Complementary Support
These four ingredients work through different pathways in the nervous system to provide comprehensive calming support without sedation.
Not a Replacement for Training
Calming supplements work best when combined with behaviour modification, routine, and environmental management. They are not a standalone solution.
Give Time to Work
Many supplements need consistent use before you see full effects. Be patient and track changes in your dog's behaviour.
Always Inform Your Vet
If your dog is on medication or has a medical condition, let your veterinarian know before introducing any new supplements.
