From humanization to preventive care

The growth of pet supplements is closely tied to the continued humanization of pet care. But the trend has matured. It is no longer simply about treating pets “like people.” It is now about applying the same preventive health mindset that consumers use for themselves to the animals in their care.

As more people adopt multivitamins, probiotics, collagen, and other wellness products for personal use, they are transferring those habits into the pet space. This is shifting the category from a reactive model — buying a product only when a pet shows a visible problem — to a more preventive and maintenance-driven model.

The health targets are expanding

As the market grows, the range of wellness needs addressed by pet supplements is also becoming broader and more sophisticated.

Among dog owners, some of the most established areas include hip, joint, and mobility support as well as probiotics. For cat owners, probiotics and formulas designed for indoor pets are particularly prominent.

At the same time, newer areas such as immune health, calming support, seasonal allergies, gut health, weight management, and cognitive support are gaining momentum.

Emerging growth zones

Weight management and cognitive health are among the most promising next-wave opportunities, especially for brands willing to support their products with stronger clinical evidence and differentiated positioning.

E-commerce is dominant, but omnichannel matters

Digital retail now plays a defining role in how pet supplements are discovered and purchased. Around 70% of pet supplement sales now occur online, reflecting a shift that accelerated during the pandemic and has not reversed.

However, this does not mean the category is purely digital. Consumers are using a mix of channels, including Amazon, Chewy, brand websites, and retailer-owned e-commerce platforms, while many still shop in physical stores as part of a broader omnichannel journey.

Ingredients and formats to watch

One of the clearest signs of category maturity is the rise of ingredient-led innovation. A number of ingredients originally associated with human wellness are gaining traction in pet products, including:

• Biotics
• Collagen
• Adaptogens
• Functional mushrooms
• L-theanine

Functional mushrooms appear particularly promising, while collagen and calming-related ingredients such as L-theanine are also generating interest. At the same time, products targeted to senior and aging pets are gaining relevance, reflecting a broader life-stage segmentation trend.

In terms of delivery systems, soft chews remain the dominant format, but newer food-adjacent options such as toppers, sauces, liquids, and highly palatable powders are attracting attention because they offer convenience and stronger integration into daily feeding routines.

Regulatory clarity and consumer education remain critical

As the category grows, so does the need for clearer positioning and better consumer understanding. One example is the blurred boundary between supplements and so-called “functional treats.”

While the term may resonate strongly with consumers, it can create regulatory complications depending on how the product is classified and marketed. This makes claims substantiation, regulatory discipline, and ingredient transparency more important than ever.

What comes next?

Industry experts remain highly optimistic about the outlook for the pet supplement market. Growth is expected to continue not only at the brand level, but across the wider value chain, including manufacturers, contractors, and ingredient suppliers.

Penetration is likely to rise, but so is spending per pet and the overall number of wellness products incorporated into everyday care.

Final thoughts

The pet supplement market is no longer a side category. It is becoming a core pillar of pet wellness, driven by changing consumer behavior, more advanced ingredient strategies, and growing demand for proactive care.

For brands, the opportunity is substantial — but so is the need for precision in positioning, formulation, education, and regulatory compliance. Those that can align all four will be best positioned to capture the next phase of growth.
