Lactium for pet food: What Is It and why is it used?

Stress and tension are common in animals. Changes in routine, transport, fireworks or visits to the veterinarian can all affect animal behavior. That is why more pet food manufacturers are looking for ingredients that can support animals during stressful situations. Lactium is one of the ingredients gaining attention in the pet nutrition market.

At ID-Ingredients, we help you find high-quality feed ingredients that match your product development goals. In this blog, you will discover what Lactium is, why it is relevant and how it can be used in pet food and supplements.

What is Lactium?

Lactium is a bioactive milk protein derived from casein, a natural protein found in milk. Through a controlled hydrolysis process, specific peptides are released from the protein structure. These peptides are studied for their potential role in relaxation and stress support.

In practice, Lactium is often used in products designed to support calm behavior in animals. The ingredient is available in powder form and can be applied in several product formats such as:

  • soft chews
  • powders
  • tablets
  • liquids
  • functional treats
 

Lactium is mainly used in products for dogs and cats, especially in supplements aimed at stress-sensitive situations.

Why use Lactium in pet food?

Pet owners increasingly look for products that support their animal’s daily wellbeing. As a result, the demand for functional ingredients continues to grow.

Lactium is often selected because it is milk-derived and easy to integrate into different formulations. In addition, it fits well in products developed for:

  • relaxation support
  • travel situations
  • stressful environments
  • changes in routine
  • training or socialization moments
 

For manufacturers, this creates opportunities to develop targeted products. Examples include calming soft chews for dogs during fireworks season or powders for cats during transport or relocation.

According to the European Food Safety Authority (EFSA), bioactive milk peptides are being researched for their applications in food and supplements.

How is Lactium used in practice?

Lactium is mainly incorporated into complementary feed and nutraceutical products. The ingredient can also be combined with other functional ingredients depending on the intended application.

Because Lactium is typically used in low inclusion levels, it can easily be integrated into daily supplements or short-term support products.

Lactium in soft chews for dogs

Soft chews are popular because they are easy to administer and highly accepted by dogs. Lactium is often combined with other ingredients commonly used in calming formulations.

Examples include:

  • magnesium
  • L-tryptophan
  • chamomile
  • valerian
  • B-vitamins
 

These combinations are often used in products intended for stressful moments such as travel, loud noises or separation situations.

Lactium in supplements for cats

Cats are generally sensitive to environmental changes. That is why powders and liquids are often preferred for feline applications.

Lactium fits well into these formulations because it can be blended easily into daily feeding routines. This allows brands to develop practical and user-friendly products for cat owners.

What are the benefits of Lactium for manufacturers?

Besides its application in calming support products, Lactium also offers practical advantages during product development.

Easy formulation possibilities

Lactium can be used in multiple dosage forms and works well in both dry and semi-moist applications. This gives manufacturers flexibility during formulation.

Suitable for premium pet products

The pet supplement market continues to move toward premium and functional concepts. Ingredients with a clear origin and targeted application are increasingly important for brand positioning.

Because Lactium is milk-derived and associated with relaxation support, it fits well within premium product ranges for dogs and cats.

Combination opportunities with other ingredients

Lactium is regularly combined with ingredients linked to:

  • calming support
  • digestion support
  • sleep routines
  • behavioral support
 

This allows brands to create complete formulas adapted to different market needs.

What should you consider when using Lactium?

As with every functional ingredient, formulation and positioning are important. Manufacturers should always evaluate:

  • target species
  • dosage form
  • palatability
  • ingredient interactions
  • regulatory positioning
 

It is also important to select high-quality raw materials from reliable suppliers. At ID-Ingredients, we support customers with ingredient sourcing and product development solutions tailored to the animal nutrition industry.
