United States Veterinary Supplements: Market Size & Forecast 2026

The U.S. veterinary supplements market covers nutritional and functional products formulated for companion animals, including dogs, cats, and increasingly equine and exotic pets. Valued at approximately $2.8 billion in 2025, the category sits within a broader global pet supplements market that is on track to reach roughly $4.6 billion by 2033. North America leads global demand, contributing close to half of worldwide revenue, supported by high pet ownership, mature retail and veterinary channels, and a strong culture of pet humanization.

• •U.S. market size estimated at approximately $2.8 billion in 2025
• •North America holds the largest regional share of global pet supplement sales
• •Product formats include chews, powders, tablets, liquids, and topicals

Premiumization of pet care, rising disposable income allocated to pets, and growing interest in preventive health are the primary engines of expansion. An expanding U.S. pet population, particularly in dog and cat ownership, combined with aging animals that require joint and mobility support, is widening the consumer base. Distribution has also improved as e-commerce and direct-to-consumer brands complement traditional veterinary and pet specialty retail channels.

• •Pet humanization driving demand for functional, health-positioned supplements
• •Aging pet population increasing need for joint, mobility, and senior care products
• •Expansion of e-commerce and DTC channels improving product accessibility

By pet type, dogs represent the largest revenue segment, followed by cats, with smaller but fast-growing categories in equine and other companion animals. By health condition, joint and mobility, skin and coat, digestive, immune, and calming or behavioral support lead demand. Geographically, the United States anchors the North American market, with California, Texas, Florida, and other high-population states contributing disproportionately due to pet ownership density and per-household spending.

• •Dogs remain the dominant pet category, with cats as the second largest segment
• •Joint, digestive, skin and coat, and calming formulas are leading condition-based segments
• •High-population U.S. states drive the largest absolute sales volumes

What are the recent trends and outlook?

Functional ingredients borrowed from human nutrition, including probiotics, omega-3 fatty acids, glucosamine, and adaptogens, are increasingly common in pet formulations. Clean-label, grain-free, and sustainably sourced claims are resonating with younger owners, while veterinary endorsements and NASC quality seals continue to shape purchase decisions. Through 2030, the market is expected to keep expanding, though growth could moderate from current highs as the category matures and broader consumer spending patterns evolve.

• •Probiotics, omega-3s, and joint-health ingredients dominate functional innovation
• •Clean-label, natural, and sustainably sourced claims are gaining purchase influence
• •Long-term growth outlook remains positive, with potential moderation as the category matures
