Protexin Serenicare is a calming support for dogs and cats, containing a novel blend of ingredients to help manage stress, anxiety and gut health.


  • Alpha-casozepine (Hydrolysed milk protein) 
    Originally derived from cow’s milk, Alpha-casozepine is a natural bioactive peptide with well-researched calming and relaxing properties.
  • L-tryptophan 
    Acting as the sole precursor to serotonin, the happy hormone, L-tryptophan is a key ingredient to help support normal mood and behaviour.
  • Calming postbiotic blend 
    A combination of heat-treated Lactobacillus rhamnosus CECT8361 and Bifidobacterium longum CECT7347, which act to help manage stress and anxiety-related behaviour.
  • FibersolTM
    A resistant maltodextrin which acts as a prebiotic to beneficial bacteria helping to promote a healthy microbiome which is key for normal gut-brain communication. 

Suitable for use in situations such as: 

  • Noise sensitivity (fireworks and thunderstorms)
  • Stressful situations (vet visits, moving home, kennels/cattery, travelling)
  • Separation anxiety 
  • Social fear (unfamiliar visitors)
  • General anxiety 

Administration instructions:
