Key Market Statistics

The global pet supplements market was valued at USD 2.8 billion in 2025. It is estimated at USD 2.9 billion in 2026 and projected to reach USD 4.6 billion by 2033, a CAGR of 6.9% from 2026 to 2033.

• North America led in 2025 with a 48.1% revenue share.
• Asia Pacific is the fastest-growing region, with a projected CAGR of 8.1%.

Market Segmentation and Key Performance Indicators

The report segments the market by type, pet type, form, application, distribution channel and region.

By type: Over-the-counter (OTC) products led in 2025 with an 86.5% share. Owners increasingly manage joint stiffness, digestion, skin and coat, anxiety and immunity themselves, using ingredients such as glucosamine, chondroitin, omega-3s and probiotics that they see as safe and convenient for long-term use. Prescription supplements are projected to grow at a 6.9% CAGR from 2026 to 2033, helped by greater veterinary engagement.

By pet type: Dogs held the largest share at 63.1% in 2025. Dog ownership is widespread, with 69.0 million U.S. households owning a dog. Cat supplements are projected to grow faster, at a 7.2% CAGR, as urban, low-maintenance pet ownership rises and owners pay closer attention to indoor and aging cats.

By form: Chewables led with a 69.8% share. Many dogs and cats resist tablets and capsules, so treat-style formats have a clear advantage. Powders are projected to grow at a 7.1% CAGR because they mix easily into food and are absorbed quickly.

By application: Hip and joint health was the largest segment at 21.6% in 2025 and is expected to stay on top. Digestive health is projected to grow at a 6.3% CAGR as owners turn to probiotics, prebiotics and digestive enzymes for gut balance and immunity.

By distribution channel: Offline channels led with a 76.5% share in 2025. Vet clinics, specialty stores and retail aisles offer guidance at the point of purchase. Online sales are projected to grow fastest, at a 9.0% CAGR, helped by subscriptions, home delivery, automated reordering and peer reviews.

Core Trends Reshaping the Industry

1. Preventive, functional pet care. Owners use supplements proactively for joint health, digestion, immunity, skin and coat, cognition and emotional wellbeing. This mirrors how people use supplements for their own health. Aging pet populations in developed markets add demand for mobility support, and interest in gut health is lifting probiotics and digestive aids.
2. Informed, label-reading owners. Access to vet guidance, online education and reviews has made buyers more cautious. They check ingredient lists, dosages and safety claims, and they prefer products free of artificial additives, fillers and allergens. Transparency and veterinary or scientific backing build trust.
3. Multifunctional formulations. Brands are combining benefits in one product, such as calming plus digestive, immune or joint support. In September 2025, Zenapet relaunched Cat Colostrum Plus as a daily powder mix-in for immune, digestive and skin and coat support.
4. Novel ingredients and delivery systems. In August 2025, Earth Buddy launched a liposomal glutathione for dogs. It is designed to improve absorption and support liver health, and it contains no hemp or CBD.
5. A push into the veterinary channel. In January 2026, Zesty Paws launched Zesty Paws Professional, its first vet-exclusive line, covering a canine probiotic and a healthy-aging supplement. In February 2025, Elanco introduced Pet Protect, a veterinarian-formulated line for skin, stress, joint and immune needs.
6. Packaging as a differentiator. Resealable pouches, portion-controlled chews, clear dosing marks and premium, human-grade designs improve shelf appeal and perceived quality.
7. Asia Pacific momentum. Urbanization, rising incomes and growing pet adoption, including in India, are shifting owners toward preventive care. Digital channels and influencer-led education add to this.
