Zylkene®, the first milk-derived nutritional supplement with clinically proven calming benefits.

Researchers have long speculated that a substance in milk might be responsible for the deep relaxation observed in newborn babies immediately after suckling. This led to the isolation of the active ingredient in Zylkene®, known as alpha-casozepine, which is:

  • derived from milk using a process that replicates the natural digestive process that occurs in newborn babies;
  • isolated without the use of chemical products.

How Zylkene® can help improve quality of life for your pet – and your family

  • Zylkene® decreases the signs of stress – including those associated with chronic stress and fear of noises
  • Zylkene® increases your pet’s receptivity to behaviour modification training.

Is Zylkene® easy to administer?

Very Easy! Zylkene® capsules contain a palatable, water-soluble powder with a milky taste that most dogs and cats love.

  • Convenient once-a-day administration.
  • Capsules can be given whole, or their contents can be added to food, liquids or treats.
