Dr Mercola Zen Pet 36.8g

Availability: Out of stock

Dr Mercola's Zen Pet contains 8 carefully selected ingredients known for their calming properties and has been created to help comfort your cat or dog during stressful times such as fireworks, travel, trips to the vet, grooming appointments, the introduction a new pet into the household, stress-related chewing, scratching and pacing.

Zen Pet is intended for occasional use before or during stressful events. For best results give to your pet a day in advance and continue to use it at the beginning of the event. 

Zen Pet is not intended to be a "personality changer in a jar” and it won't change unwanted behaviours. For example it won't calm your hyperactive puppy, nor will it stop your dog from chasing your cat or correcting other behavioral problems as only consistent training and behavior modification can do that.

Simply stir the chicken-flavoured Zen Pet powder into your pet's wet food or dust on dry food. Alternatively mix with broth or feed with a treat.




 What is in Zen Pet? Dr Mercola has carefully selected eight ingredients that from their extensive research and clinical experience are safe and effective.

  • Organic Holy Basil (or Tulsi) - From Mercola certified organic growers in India
  • L-Theanine - Stimulates mentally alert, yet calming, alpha brain waves
  • Organic Rhodiola rosea - A true adaptogen harvested in Siberia
  • Ashwagandha (or Indian Ginseng) - Another exceptional adaptogen to help your pet's body adapt to physical, chemical, and environmental stress
  • German Chamomile - A popular herb with calming qualities
  • 5-HTP - Converts to serotonin which supports feelings of well-being
  • GABA - Helps tell the brain to slow down during times of stress
  • Vitamin B6 - Supports a healthy nervous system and mood, and helps with serotonin production

Please note: L-Theanine increases the potency of chemotherapeutic drugs. If your pet is receiving chemotherapy treatment, check with your vet before using. In addition, check with your vet if your pet is taking prescription anti-depressants. Contains chicken flavour and beef fat, so avoid use if your pet is allergic to either.


  • Zen Pet is intended for occasional use before or during stressful events. Long-term continuous use may reduce potential benefits
  • Stir Zen Pet into your pet's wet food, dust on dry food, mix with broth and feed, or feed with a treat. Pets find the chicken flavour appealing
  • Feed to your pet a day in advance of expected stressful event, if possible. If not possible, you can still use Zen Pet at the beginning of stressful event
  • Zen Pet is not a substitute for appropriate training
