How quickly will Calm-K9 Max Strength work?

+

Calm-K9 Max Strength is usually rapid acting and some changes can be seen straight away. However, just like humans, all dogs are different and others might take longer to see imporvements so we recommend allowing up to 50 days.

Is this dog supplement suitable for all breeds, ages and sizes of dog?

+

Yes! Calm-K9 can be fed to any dog over 8 weeks old. The only thing that affects the daily dosage of Calm-K9 Max Strength is your dog’s size. See our feeding info chart for more details.

Please Note:
Calm-K9 Max Strength should not be used in conjunction with SSRIs (Selective Serotonin Reuptake Inhibitors) unless explicitly approved by your veterinarian. Always consult with your vet before introducing new supplements to your dog's regimen, especially if your dog is on prescription medications.

What is in Calm-K9 Max Strength?

+

Calm-K9 Max Strength is designed to naturally support calm behaviour and emotional balance in dogs, by nurturing the powerful connection between the gut and the brain.

Each spoonful contains:

L-Tryptophan (250mg) – an essential amino acid that supports serotonin production, helping promote calm behaviour

Passiflora (Passionflower) Powder (100mg) – a traditional botanical used to support relaxation and emotional balance

L-Glutamine (100mg) – supports the gut lining, which plays a key role in mood regulation through the gut-brain axis

Lemon Balm Extract (25mg) – known for its calming and mood-balancing effects

Enterococcus Faecium (3x10¹¹ CFU/kg) – a beneficial probiotic to support gut health and reduce stress responses

Beta Glucans & MOS (50mg each) – support immune health and gut stability, especially under stress

All of this is delivered in a gentle, tasty powder with natural flavouring, making daily calm support stress-free and straightforward.

Is there any scientific evidence that the ingredients in Calm-K9 Max Strength can aid calmness?

+

Calm-K9 Max Strength contains scientifically backed ingredients proven to promote calmness and reduce anxiety in dogs. Here’s how it works:

Serotonin and Tryptophan

Serotonin is a neurotransmitter responsible for regulating mood, optimism, appetite, aggression, impulse control, and anxiety.
The body produces serotonin using tryptophan, an essential amino acid that must be obtained through diet.
Once absorbed, tryptophan is converted into serotonin, which has anti-anxiety and calming effects through its neurological pathway.

Key Ingredients

Lemon Balm
Passiflora (Passionflower)
Probiotics

My dog is going under general anaesthetic. Can I still feed Calm-K9 Max Strength?

+

As Calm-K9 is centrally-acting, to be safe, we recommend stopping Calm-K9 Max Strength & Calm-K9 Senior Boost Max Strength 3 days before the operation and picking up again 3 days after. All other supplements can be given the day before and restarted after 48 hours.

What is the optimum time to feed Calm-K9 Max Strength?

+

It doesn't matter at all what time you give Calm-K9. Some of our Health Heroes like to give it in the morning and some in the evening.
